    Overall Summary
    • Influenza activity in Canada remained at inter-seasonal levels during this 2-week period.
    • The number of laboratory tests positive for all respiratory viruses was similar to previous weeks.
    • The ILI consultation rate was stable in recent weeks.
    NOTE: This is the first report for the 2013-2014 influenza season. Fortnightly reports will continue until October 11, 2013. Laboratory detections reported through the Respiratory Virus Detection Surveillance System and influenza activity level maps continue to be updated weekly on the FluWatch website.

    Influenza Activity (geographic spread) and Outbreaks

    The number of regions reporting influenza activity was at inter-seasonal levels in weeks 35 and 36. During this period, six regions reported sporadic activity (Figure 1). Localized activity has not been reported since week 26 of the 2012-13 season (Figure 2). No new influenza outbreaks were reported in weeks 35 or 36 (Figure 3).

    Canada, Week 36





    Note: Influenza activity levels, as represented on this map, are assigned and reported by Provincial and Territorial Ministries of Health, based on laboratory confirmations, sentinel ILI rates (see graphs and tables) and reported outbreaks. Please refer to detailed definitions on the last page. For areas where no data is reported, late reports from these provinces and territories will appear on the FluWatch website.

    Influenza and Other Respiratory Virus Detections

    The overall percentage of positive influenza tests was low and stable, at 0.6% in week 35 and 0.3% in week 36. Among the ten influenza viruses detected in weeks 35 and 36, eight were influenza A (Table 1). Detailed information on age and type/subtype was complete for eight cases. Five of the eight cases were adults 45-64 years of age with A(H1N1)pdm09 (Table 2).
    The percentage of positive tests for rhinovirus increased during this 2-week period from 17.7% in week 34 to 23.1% in week 36; although the number of positive tests was similar to previous weeks. The percentages of positive tests for other respiratory viruses were low in week 36: parainfluenza (3.1%), human metapneumovirus (hMPV) (0.1%), respiratory syncytial virus (RSV) (0.8%), coronavirus (0%) and adenovirus (1.7%) (Figure 5)<SUP>*</SUP>.

    Severe Respiratory Illness Surveillance

    Paediatric Influenza Hospitalizations and Deaths (IMPACT)
    No laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalizations have been reported in any of the 12 hospitals participating in the Immunization Monitoring Program Active (IMPACT) network in weeks 35 or 36.
    Note: The number of hospitalizations reported through IMPACT represents a subset of all influenza-associated paediatric hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

    Adult Influenza Hospitalizations and Deaths (PCIRN)
    Active surveillance of laboratory-confirmed influenza-associated adult (≥16 years of age) hospitalizations reported by the PHAC/CIHR Influenza Research Network (PCIRN) Serious Outcomes Surveillance (SOS) network concluded for the 2012-13 influenza season on April 30th, 2013. The PCIRN-SOS network continues to report limited data on laboratory-confirmed cases of influenza identified through passive surveillance at 15 out of 17 hospital sites, and active surveillance will start again on November 15th, 2013. No new hospitalizations, ICU admissions or deaths were reported in weeks 35 and 36.

    Note: The number of hospitalizations reported through PCIRN represents a subset of all influenza-associated adult hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

    Provincial/Territorial Influenza Hospitalizations and Deaths (Aggregate Surveillance System<SUP>*</SUP>)

    In the first two weeks of the 2013-14 season, two laboratory-confirmed influenza-associated hospitalizations were reported from five of the nine participating provinces and territories*. Both cases were adults 45-64 years of age with A(H1N1)pdm09, of which one was admitted to the ICU.
    * Note: The number of new influenza-associated hospitalizations and deaths reported by the Aggregate Surveillance System each week may be overestimated, as it may include retrospective updates to data from Ontario for previous weeks. These data may also include cases reported by the IMPACT and PCIRN networks. Influenza-associated hospitalizations are not reported to PHAC by the following Provinces and Territory: BC, NU, QC, NS, and NB. Only hospitalizations that require intensive medical care are reported by Saskatchewan. ICU admissions are not reported in Ontario.

    Tropical Regions

    Asia & Africa: Influenza activity remained low in most countries in tropical Asia. Hong Kong, China Special Administrative Region, reported a switch from A(H1N1)pdm09 circulation to predominantly A(H3N2). Countries in Southeast Asia reported decreasing circulation of influenza A. Most countries in central Africa reported low or decreasing influenza activity, although Côte d'Ivoire and Ghana reported continued influenza circulation.
    Carribean, Central America & tropical South America: Influenza activity in Caribbean and Central America continued to decrease, with influenza A(H3N2) and A(H1N1)pdm09 co-circulating in varying proportions in different countries. In tropical South America, influenza activity decreased in Bolivia, Brazil, Colombia and Venezuela. Peru reported a sharp increase in A(H1N1)pdm09 circulation in weeks 29-32, but detections have been decreasing in weeks 33 and 34. In Bolivia, the proportion of SARI hospitalizations showed an increasing trend, primarily associated with A(H1N1)pdm09.

    Southern Hemisphere

    Influenza activity continued to decline in countries in South America as well as in South Africa. Activity in Oceania has been increasing in recent weeks and may be reaching its plateau.

    South America - Southern Cone: Influenza and RSV circulation declined in several countries in temperate South America, although RSV continued to be the predominant respiratory virus in the region. Influenza detections peaked at the end of June, with a predominance of A(H1N1)pdm09 in all countries except Paraguay, where A(H3N2) was predominant. In Argentina, laboratory detections seem to have peaked in week 27, and the number of ILI reports declined and was within the expected range in week 34. In Chile, the ILI activity rate in week 34 was similar to previous weeks; RSV and influenza detections declined from weeks 29-33 but rose slightly in week 34. In Paraguay, ILI activity increased in week 34 although influenza A(H3N2) and RSV detections have been declining in weeks 28-34. In Brazil, influenza detections have been declining since a peak in week 24, with A(H1N1)pdm09 and influenza B co-circulating.

    South Africa: Circulation of A(H1N1)pdm09 was reported from April to July 2013, with a peak in laboratory detections in week 23. Influenza circulation in weeks 31-34 has shifted to a predominance of A(H3N2) and influenza B, observed among both ILI and SARI cases.

    Australia & New Zealand: Compared to recent years, the start of the 2013 influenza season has been delayed in Australia and New Zealand. In New Zealand, consultation rates for ILI remained below the baseline level, and below the level of the previous two seasons. Laboratory detections of influenza increased in week 35 but declined in week 36. Among the 1183 influenza viruses identified between weeks 1 and 36, 47.2% were influenza B. Among the 405 subtyped influenza A viruses, 75.6% were A(H3N2). In Australia, the increase in influenza activity has slowed and activity remains lower than the previous 2 seasons. The ILI consultation rate increased in recent weeks, but declined in week 35; 25% of sentinel ILI specimens were positive for influenza between August 26 and September 1. The number of laboratory-confirmed influenza notifications continued to increase since early June. Among the 14,068 influenza viruses identified between 1 January and 30 August 2013, 65% were influenza A. Although the majority of influenza A have not been subtyped, to date approximately 15% have been A(H1N1)pdm09 in 2013 compared to <1% during the 2012 season. Most influenza B viruses characterized were from the Yamagata lineage.

    Since 30 August 2013, WHO has reported ten additional cases of MERS-CoV infection: eight cases, including three deaths, in Saudi Arabia; one case in Qatar who subsequently died; and one case in Tunisia (reported on 22 May 2013 as a deceased probable case, now confirmed). Four of the cases in Saudi Arabia are family contacts of at least one confirmed case. Two are asymptomatic paediatric cases. The remaining two are adults with underlying medical conditions, and one has died. Two healthcare workers with severe pneumonia were reported from the same health care facility. One had no known exposure to animals, or to a confirmed MERS-CoV case, and has died. The second health care worker was reported to be in critical condition. As of 12 September, 2013, 114 laboratory-confirmed cases of human infection with MERS-CoV have been reported, including 54 deaths. Most patients are male (61%; 67 of 110 cases) and range in age from 14 months to 94 years (median 50 years, n=107).

      Overall Summary
      • Influenza activity in Canada remained at inter-seasonal levels during this 2-week period.
      • The number of laboratory tests positive for all respiratory viruses was similar to previous weeks.
      • The ILI consultation rate was stable in recent weeks, with a slight increase seen in week 38.
      NOTE: Fortnightly reports will continue until October 11, 2013. Laboratory detections reported through the Respiratory Virus Detection Surveillance System and influenza activity level maps continue to be updated weekly on the FluWatch website.

      Influenza Activity (geographic spread) and Outbreaks

      The number of regions reporting influenza activity was at inter-seasonal levels in weeks 37 and 38. During this period, four regions reported sporadic activity (Figure 1). Localized activity has not been reported since week 26 of the 2012-13 season (Figure 2). No new influenza outbreaks were reported in weeks 37 or 38 (Figure 3).

      Influenza and Other Respiratory Virus Detections

      The overall percentage of positive influenza tests was low and stable, at 0.3% in week 37 and 0.2% in week 38. Among the seven influenza viruses detected in weeks 37 and 38, five were influenza A (Table 1). Cumulative influenza virus detections by type/subtype to date are as follows: 76.5% influenza A [7.7% A(H3), 46.2% A(H1N1)pdm09 and 45.2% A(unsubtyped)] and 23.5% influenza B (Table 1).
      Detailed information on age and type/subtype has been received for 14 cases to date this season (Table 2). The proportion of cases by age group is as follows: 21.4% <5 years; 0% between 5-19 years; 7.1% between 20-44 years; 57.1% between 45-64 years; and 14.3% ≥65 years of age.
      The percentage of positive tests for rhinovirus increased during this 2-week period from 23.1% in week 36 to 30.3% in week 38; the number of positive tests also increased compared to previous weeks. The percentages of positive tests for other respiratory viruses were low in week 38: parainfluenza (2.9%), human metapneumovirus (hMPV) (0.1%), respiratory syncytial virus (RSV) (0.4%), coronavirus (0.1%) and adenovirus (1.3%) (Figure 5)<SUP>*</SUP>.

      Severe Respiratory Illness Surveillance

      Paediatric Influenza Hospitalizations and Deaths (IMPACT)
      No laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalizations have been reported in any of the 12 hospitals participating in the Immunization Monitoring Program Active (IMPACT) network in weeks 37 or 38.
      Note: The number of hospitalizations reported through IMPACT represents a subset of all influenza-associated paediatric hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.
      Adult Influenza Hospitalizations and Deaths (PCIRN)
      Active surveillance of laboratory-confirmed influenza-associated adult (≥16 years of age) hospitalizations reported by the PHAC/CIHR Influenza Research Network (PCIRN) Serious Outcomes Surveillance (SOS) network concluded for the 2012-13 influenza season on April 30th, 2013. The PCIRN-SOS network continues to report limited data on laboratory-confirmed cases of influenza identified through passive surveillance, and active surveillance will start again on November 15th, 2013. No new hospitalizations, ICU admissions or deaths were reported in week 37 and no data was reported in week 38.
      Note: The number of hospitalizations reported through PCIRN represents a subset of all influenza-associated adult hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

      In weeks 37 and 38, no new laboratory-confirmed influenza-associated hospitalizations were reported from participating provinces and territories<SUP>*</SUP>. To date this season, two influenza-associated hospitalizations have been reported. Both cases were reported in adults 45-64 years of age. One ICU admission was reported among the two cases and no deaths were reported. The influenza-associated hospitalizations reported were influenza A (H1N1).
      * Note: The number of new influenza-associated hospitalizations and deaths reported by the Aggregate Surveillance System each week may be overestimated, as it may include retrospective updates to data from Ontario for previous weeks. These data may also include cases reported by the IMPACT and PCIRN networks. Influenza-associated hospitalizations are not reported to PHAC by the following Provinces and Territory: BC, NU, QC, NS, and NB. Only hospitalizations that require intensive medical care are reported by Saskatchewan. ICU admissions are not reported in Ontario.

      Tropical Regions

      Asia & Africa: Influenza activity remained low in most countries in tropical Asia. Hong Kong, China Special Administrative Region, continued to observe a predominance of A(H3N2) after a switch from A(H1N1)pdm09 a few weeks earlier. Countries in Southeast Asia reported decreasing circulation of influenza A. Most countries in central Africa reported low or decreasing influenza activity, although Côte d’Ivoire, Ghana and Kenya reported continued influenza circulation.
      Carribean, Central America & tropical South America: Influenza activity in Caribbean and Central America continued to decrease and appears to have come to an end. In the majority of countries still seeing activity, co-circulation of influenza A(H3N2) and A(H1N1)pdm09 was reported, with the exception of Honduras, where influenza B was circulating. In tropical South America, acute respiratory virus activity continued to decrease and co-circulation of influenza A(H1N1)pdm09 and influenza B was reported in Bolivia, Ecuador and Peru.

      Southern Hemisphere

      Influenza activity continued to decline in countries in South America as well as in South Africa. Activity in Oceania has been increasing in recent weeks and may be reaching its plateau.
      South America - Southern Cone: Acute respiratory virus activity was within the expected level for this time of year in all countries except Paraguay where ILI activity was elevated. RSV predominated in most countries with co-circulation of influenza B and A(H3N2) in Paraguay and Uruguay. In Argentina, laboratory detections peaked in week 27, and the number of ILI reports declined and was within the expected range in week 37. In Chile, the ILI activity rate in week 37 was similar to previous weeks; RSV and influenza detections declined from weeks 29-33, rose slightly in week 34, and declined again in week 35 and 36. In Paraguay, ILI activity decreased in week 37, but influenza virus detections increased from the previous week. In Uruguay, influenza activity increased in week 37. In South and Southeast Brazil, influenza activity continued to decrease, with co-circulation of influenza A(H1N1)pdm09 and influenza B reported.
      South Africa: Circulation of A(H1N1)pdm09 was reported from April to July 2013, with a peak in laboratory detections in week 23. Influenza circulation in weeks 31-34 has shifted to a predominance of A(H3N2) and influenza B, observed among both ILI and SARI cases.

      Australia & New Zealand: Compared to recent years, the start of the 2013 influenza season has been delayed in Australia and New Zealand. In New Zealand, consultation rates for ILI remained below the baseline level, and below the level of the previous two seasons. Laboratory detections of influenza increased in week 37 from week 36, but declined slightly in week 38. Among the 1594 influenza viruses identified between weeks 1 and 38, 43.8% were influenza B. Among the 600 subtyped influenza A viruses, 75.5% were A(H3N2). Australia has not released an updated report.

      Since 13 September 2013, WHO has reported 18 additional cases of MERS-CoV infection in Saudi Arabia. The cases range in age from three to 75 years. Of the 18 cases, data was provided for eight cases. All eight are contacts of confirmed cases. Five are males and four are health care workers. Two of the cases were symptomatic and had underlying medical conditions. The remainder were asymptomatic or had mild symptoms. Four deaths were reported, with three occurring in Saudi Arabia. The fourth death was a previously laboratory-confirmed patient in Qatar. As a result of a recent update to the WHO laboratory testing recommendations, two patients, reported in Italy in June 2013 as laboratory-confirmed with MERS-CoV, have been reclassified as probable cases. As of 26 September 2013, 130 laboratory-confirmed cases of human infection with MERS-CoV have been reported, including 58 deaths. Most patients are male (63%, 77/124) and range in age from 2 to 94 years (median 50 years, n=125).

        Influenza and Other Respiratory Virus Detections

        The overall percentage of positive influenza tests was low and stable, at 0.2% in week 39 and 0.3% in week 40. Among the nine influenza viruses detected in weeks 39 and 40, seven were influenza A (Table 1). Cumulative influenza virus detections by type/subtype to date are as follows: 76.9% influenza A [10% A(H3), 45% A(H1N1)pdm09 and 45% A(unsubtyped)] and 23.1% influenza B (Table 1).
        Detailed information on age and type/subtype has been received for 22 cases to date this season (Table 2). The proportion of cases by age group is as follows: 18.2% <5 years; 0% between 5-19 years; 18.2% between 20-44 years; 54.5% between 45-64 years; and 9.1% ≥65 years of age.
        The percentage of positive tests for rhinovirus increased slightly from 31.3% in week 38 to 31.8% in week 39, then decreased to 28.8% in week 40. The percentage of positive tests for parainfluenza increased from 2.9% in week 38 to 4.1% in week 40. The percentages of positive tests for other respiratory viruses were low in week 40: human metapneumovirus (hMPV) (0.4%), respiratory syncytial virus (RSV) (0.4%), coronavirus (0.4%) and adenovirus (1.2%) (Figure 5)<SUP>*</SUP>.

        Severe Respiratory Illness Surveillance

        Paediatric Influenza Hospitalizations and Deaths (IMPACT)

        No laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalizations have been reported in any of the 12 hospitals participating in the Immunization Monitoring Program Active (IMPACT) network in weeks 39 or 40.

        Note: The number of hospitalizations reported through IMPACT represents a subset of all influenza-associated paediatric hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

        Adult Influenza Hospitalizations and Deaths (PCIRN)
        Active surveillance of laboratory-confirmed influenza-associated adult (≥16 years of age) hospitalizations reported by the PHAC/CIHR Influenza Research Network (PCIRN) Serious Outcomes Surveillance (SOS) network concluded for the 2012-13 influenza season on April 30th, 2013. The PCIRN-SOS network continues to report limited data on laboratory-confirmed cases of influenza identified through passive surveillance, and active surveillance will start again on November 15th, 2013. Two new hospitalizations were reported in weeks 39 and 40, both adults with influenza A, one 45-64 years of age and one ≥65 years of age. No ICU admissions or deaths were reported.

        Note: The number of hospitalizations reported through PCIRN represents a subset of all influenza-associated adult hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

        Provincial/Territorial Influenza Hospitalizations and Deaths (Aggregate Surveillance System<SUP>*</SUP>)

        In weeks 39 and 40, one new laboratory-confirmed influenza-associated hospitalization was reported from participating provinces and territories<SUP>*</SUP>. The case was a child 0-4 years of age with influenza A(H3N2). To date this season, three influenza-associated hospitalizations have been reported. The two previous cases were adults 45-64 years of age with influenza A(H1N1)pdm09. One ICU admission was reported among the three cases and no deaths were reported.

        * Note: The number of new influenza-associated hospitalizations and deaths reported by the Aggregate Surveillance System each week may be overestimated, as it may include retrospective updates to data from Ontario for previous weeks. These data may also include cases reported by the IMPACT and PCIRN networks. Influenza-associated hospitalizations are not reported to PHAC by the following Provinces and Territory: BC, NU, QC, NS, and NB. Only hospitalizations that require intensive medical care are reported by Saskatchewan. ICU admissions are not reported in Ontario.

          Overall Summary
          • Influenza activity in Canada remained at inter-seasonal levels in week 41.
          • Few laboratory detections of influenza have been reported to date this season; rhinovirus and parainfluenza were the predominant respiratory viruses in circulation in week 41.
          • The ILI consultation rate has followed a gradual upward trend over the past four weeks.
          Influenza Activity (geographic spread) and Outbreaks

          In week 41, four regions (in BC, AB(2) and ON) reported sporadic activity (Figure 1). Localized activity has not been reported since week 26 of the 2012-13 season (Figure 2). No new influenza outbreaks were reported in week 41 (Figure 3).

          Note: Influenza activity levels, as represented on this map, are assigned and reported by Provincial and Territorial Ministries of Health, based on laboratory confirmations, sentinel ILI rates (see graphs and tables) and reported outbreaks. Please refer to detailed definitions on the last page. For areas where no data is reported, late reports from these provinces and territories will appear on the FluWatch website.

          Influenza and Other Respiratory Virus Detections

          The overall percentage of positive influenza tests was low and stable, at 0.4% in week 41. Among the seven influenza viruses detected in week 41, five were influenza A (Table 1). Cumulative influenza virus detections by type/subtype to date are as follows: 75.8% influenza A [16% A(H3), 40% A(H1N1)pdm09 and 44% A(unsubtyped)] and 24.2% influenza B (Table 1).
          Detailed information on age and type/subtype has been received for 27 cases to date this season (Table 2). The proportion of cases by age group is as follows: 18.5% <5 years; 0% between 5-19 years; 18.5% between 20-44 years; 48.1% between 45-64 years; and 14.8% ≥65 years of age.
          The percentage of positive tests for rhinovirus decreased slightly from 33.6% in week 40 to 31.9% in week 41. The percentage of positive tests for parainfluenza was stable at 4.1% in week 41. The percentages of positive tests for other respiratory viruses were low in week 41: human metapneumovirus (hMPV) (0.3%), respiratory syncytial virus (RSV) (0.8%), coronavirus (0.3%) and adenovirus (1.7%) (Figure 5)<SUP>*</SUP>.

          Severe Respiratory Illness Surveillance

          Paediatric Influenza Hospitalizations and Deaths (IMPACT)

          No laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalizations have been reported in any of the 12 hospitals participating in the Immunization Monitoring Program Active (IMPACT) network in week 41.

          Note: The number of hospitalizations reported through IMPACT represents a subset of all influenza-associated paediatric hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

          Adult Influenza Hospitalizations and Deaths (PCIRN)

          Active surveillance of laboratory-confirmed influenza-associated adult (≥16 years of age) hospitalizations reported by the PHAC/CIHR Influenza Research Network (PCIRN) Serious Outcomes Surveillance (SOS) network concluded for the 2012-13 influenza season on April 30th, 2013. The PCIRN-SOS network continues to report limited data on laboratory-confirmed cases of influenza identified through passive surveillance, and active surveillance will start again on November 15th, 2013. One new hospitalization and ICU admission was reported in week 41 in an adult 45-64 years of age with influenza A. No deaths were reported.

          From week 35 to week 41, three influenza-associated adult hospitalizations have been reported by the PCIRN-SOS network, all with influenza A(unsubtyped). Two were 45-64 years of age, and one ≥65 years of age. ICU admission was required for one hospitalization and no deaths have been reported.

          Note: The number of hospitalizations reported through PCIRN represents a subset of all influenza-associated adult hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.
          Provincial/Territorial Influenza Hospitalizations and Deaths (Aggregate Surveillance System<SUP>*</SUP>)

          In week 41, one new laboratory-confirmed influenza-associated hospitalization was reported from participating provinces and territories (five of eight reporting in week 41).<SUP>*</SUP> The case was reported in an adult 45-64 years of age with influenza B. No ICU admissions or deaths were reported.

          To date this season, four influenza-associated hospitalizations have been reported. Three cases were reported in adults 45-64 years of age, and one was reported in a child 0-4 years; 3 (75%) had influenza A [of which 1 was A(H3) and 2 was A(H1)], and 1 (25%) had influenza B. One ICU admission was reported in an adult among the four cases and no deaths were reported.

          * Note: The number of new influenza-associated hospitalizations and deaths reported by the Aggregate Surveillance System each week may be overestimated, as it may include retrospective updates to data from Ontario for previous weeks. These data may also include cases reported by the IMPACT and PCIRN networks. Influenza-associated hospitalizations are not reported to PHAC by the following Provinces and Territory: BC, NU, QC, NS, and NB. Only hospitalizations that require intensive medical care are reported by Saskatchewan. ICU admissions are not reported in Ontario.

            Overall Summary
            • Influenza activity in Canada remained at inter-seasonal levels in week 42.
            • Few laboratory detections of influenza have been reported to date this season; rhinovirus and parainfluenza were the predominant respiratory viruses in circulation in week 42.
            • The ILI consultation rate has followed a gradual upward trend over the past five weeks.
            Influenza Activity (geographic spread) and Outbreaks

            In week 42, five regions (in AB(3), ON and QC) reported sporadic activity (Figure 1). Localized activity has not been reported since week 26 of the 2012-13 season (Figure 2). No new influenza outbreaks were reported in week 42 (Figure 3).

            Note: Influenza activity levels, as represented on this map, are assigned and reported by Provincial and Territorial Ministries of Health, based on laboratory confirmations, sentinel ILI rates (see graphs and tables) and reported outbreaks. Please refer to detailed definitions on the last page. For areas where no data is reported, late reports from these provinces and territories will appear on the FluWatch website.

            Influenza and Other Respiratory Virus Detections

            The overall percentage of positive influenza tests was low and stable, at 0.2% in week 42. Among the three influenza viruses detected in week 42, all were influenza A (Table 1). Cumulative influenza virus detections by type/subtype to date are as follows: 78% influenza A [14% A(H3), 39% A(H1N1)pdm09 and 46% A(unsubtyped)] and 22% influenza B (Table 1).
            Detailed information on age and type/subtype has been received for 29 cases to date this season (Table 2). The proportion of cases by age group is as follows: 20.7% <5 years; 0% between 5-19 years; 17.2% between 20-44 years; 44.8% between 45-64 years; and 17.2% ≥65 years of age.
            The percentage of positive tests for rhinovirus was similar to week 41, at 31.0% in week 42. The percentage of positive tests for parainfluenza increased slightly from 4.1% in week 41 to 5.5% in week 42. The percentages of positive tests for other respiratory viruses were low in week 42: human metapneumovirus (hMPV) (0.1%), respiratory syncytial virus (RSV) (0.6%), coronavirus (0.6%) and adenovirus (1.7%) (Figure 5)<SUP>*</SUP>.

            Severe Respiratory Illness Surveillance

            Paediatric Influenza Hospitalizations and Deaths (IMPACT)

            In week 42, one laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalization was reported by the Immunization Monitoring Program Active (IMPACT) network: a child 2-4 years of age with influenza A(unsubtyped).

            To date this season, a total of two influenza-associated paediatric hospitalizations have been reported by the IMPACT network. The previous case was a child 2-4 years of age, hospitalized in week 41 with influenza B for whom ICU admission was required. No deaths have been reported.

            Note: The number of hospitalizations reported through IMPACT represents a subset of all influenza-associated paediatric hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

            Adult Influenza Hospitalizations and Deaths (PCIRN)

            Active surveillance of laboratory-confirmed influenza-associated adult (≥16 years of age) hospitalizations reported by the PHAC/CIHR Influenza Research Network (PCIRN) Serious Outcomes Surveillance (SOS) network concluded for the 2012-13 influenza season on April 30th, 2013. The PCIRN-SOS network continues to report limited data on laboratory-confirmed cases of influenza identified through passive surveillance, and active surveillance will start again on November 15th, 2013. No hospitalizations, ICU admissions or deaths were reported in week 42.
            To date this season, three influenza-associated adult hospitalizations have been reported by the PCIRN-SOS network, all with influenza A(unsubtyped). Two were 45-64 years of age, and one ≥65 years of age. ICU admission was required for one hospitalization and no deaths have been reported.

            Note: The number of hospitalizations reported through PCIRN represents a subset of all influenza-associated adult hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

            Provincial/Territorial Influenza Hospitalizations and Deaths (Aggregate Surveillance System<SUP>*</SUP>)
            In week 42, one new laboratory-confirmed influenza-associated hospitalization was reported from participating provinces and territories.<SUP>*</SUP> The case was reported in a child 0-4 years of age with influenza A(unsubtyped). No ICU admissions or deaths were reported.

            To date this season, seven influenza-associated hospitalizations have been reported. One case was reported in an adult ≥65 years of age, three cases were reported in adults 45-64 years of age, and three cases in children 0-4 years of age. Five (71%) cases had influenza A [one A(H3), two A(H1), and two A(unsubtyped)], and two (29%) had influenza B. One ICU admission was reported in an adult 45-64 years of age and no deaths have been reported.

            * Note: The number of new influenza-associated hospitalizations and deaths reported by the Aggregate Surveillance System each week may be overestimated, as it may include retrospective updates to data from Ontario for previous weeks. These data may also include cases reported by the IMPACT and PCIRN networks. Influenza-associated hospitalizations are not reported to PHAC by the following Provinces and Territory: BC, NU, QC, NS, and NB. Only hospitalizations that require intensive medical care are reported by Saskatchewan. ICU admissions are not reported in Ontario.

              Overall Summary
              • Influenza activity in Canada increased slightly in week 43.
              • While rhinovirus and parainfluenza continued to be the predominant respiratory viruses in circulation in week 43, laboratory detections of influenza increased.
              • Both paediatric and adult hospitalizations with influenza were reported in week 43.
              • After increasing in late September, the ILI consultation rate has been stable in weeks 40-43.
              Note: The presentation of the FluWatch report has been updated for the 2013-14 influenza season in order to improve the readability and interpretation of the report. Graphs and tables related to influenza activity levels, laboratory data and ILI data have been modified. Additional graphs and tables were added to the sections related to surveillance of antiviral prescriptions and hospitalizations with influenza.

              Influenza/ILI Activity (geographic spread)

              In week 43, seven regions (in BC(1), AB(2), ON(2) and QC(2)) reported sporadic activity (Figure 1). The number of regions reporting sporadic activity has increased over the past two weeks.

              Influenza and Other Respiratory Virus Detections

              The number of positive influenza tests increased from a range of 3 to 7 over weeks 35 to 42, to 21 in week 43. The percentage of positive influenza tests increased slightly from 0.2% in week 42 to 1.0% in week 43 (Figure 2). Among the 21 influenza viruses detected in week 43, 62% were influenza A. Cumulative influenza virus detections by type/subtype to date have been predominantly influenza A (72%) with a nearly equal mix of A(H3) and A(H1N1)pdm09 among those subtyped (Table 1). Detailed information on age and type/subtype has been received for 49 cases to date this season. The majority of cases have been adults 45-64 years of age (49%), followed by children under 5 years of age (22%) (Table 2).

              The number of positive tests for both rhinovirus and parainfluenza declined in week 43, although they remained the predominant viruses detected. The number of positive tests for both adenovirus and RSV increased slightly. The numbers of positive tests for human metapneumovirus and coronavirus remained low in week 43 (Figure 3).

              Influenza Strain Characterizations

              During the 2013-2014 influenza season, the National Microbiology Laboratory (NML) has antigenically characterized six influenza viruses [two A(H3N2), two A(H1N1)pdm09 and two influenza B]. All viruses were similar to the strains recommended by the WHO for the 2013-14 seasonal influenza vaccine (Figure 4).
              Figure 4. Influenza strain characterizations, Canada, 2013-14, N =6

              The NML receives a proportion of the number of influenza positive specimens from provincial laboratories for strain characterization and antiviral resistance testing. Characterization data reflect the results of haemagglutination inhibition (HAI) testing compared to the reference influenza strains recommended by WHO.
              The recommended components for the 2013-2014 northern hemisphere trivalent influenza vaccine include: an A/California/7/2009 (H1N1)pdm09-like virus, an A(H3N2) virus antigenically like the cell-propagated prototype virus A/Victoria/361/2011b, and a B/Massachusetts/2/2012-like virus (Yamagata lineage).

              Antiviral Resistance

              During the 2013-2014 influenza season, NML has tested six influenza viruses for resistance to oseltamivir and zanamivir, and all were sensitive. Four influenza A viruses were tested for amantadine resistance, and all were resistant (Table 3).

              Influenza-like Illness (ILI) Consultation Rate

              The national influenza-like-illness (ILI) consultation rate decreased slightly from 23.4/1,000 in week 42 to 20.4/1,000 in week 43 (Figure 5).

The calculation of the average ILI consultation rate over 17 seasons was aligned with influenza activity in each season. In BC, AB, and SK, data is compiled by a provincial sentinel surveillance program for reporting to FluWatch. The number of sentinel physicians in each province or territory is as follows: BC(21), AB(80), SK(11), MB(18), ON(169), QC(14), NB(29), NS(26), PE(4), NL(16), NU(1), NT(14), YT(13). Not all sentinel physicians report every week.

              Sentinel Hospital Influenza Surveillance

              Paediatric Influenza Hospitalizations and Deaths (IMPACT)
              In week 43, two laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalizations were reported by the Immunization Monitoring Program Active (IMPACT) network: one child 0-5 months of age and one 2-4 years of age, both with influenza B (Figure 8a).
              To date this season, a total of five influenza-associated paediatric hospitalizations have been reported by the IMPACT network: two children 0-5 months of age and three 2-4 years of age. One ICU admission was required in a child 2-4 years of age with influenza B. No deaths have been reported (Figure 9a and Table 4).
              Note: The number of hospitalizations reported through IMPACT represents a subset of all influenza-associated paediatric hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.
              Adult Influenza Hospitalizations and Deaths (PCIRN)
              Active surveillance of laboratory-confirmed influenza-associated adult (≥16 years of age) hospitalizations reported by the PHAC/CIHR Influenza Research Network (PCIRN) Serious Outcomes Surveillance (SOS) network will begin on November 15th 2013. The PCIRN-SOS network continues to report limited data on laboratory-confirmed cases of influenza identified through passive surveillance. Two new hospitalizations were reported in week 43, one 45-64 years of age and one ≥65 years of age, both with influenza A. No ICU admissions or deaths were reported in week 43 (Figure 8b).
              To date this season, five influenza-associated hospitalizations have been reported by the PCIRN-SOS network, all adults over 45 years of age with influenza A. ICU admission was required for one hospitalization and no deaths have been reported (Figure 9b and Table 5).
              Note: The number of hospitalizations reported through PCIRN represents a subset of all influenza-associated adult hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

              Provincial/Territorial Influenza Hospitalizations and Deaths

              In week 43, six new laboratory-confirmed influenza-associated hospitalizations were reported from participating provinces and territories. <SUP>*</SUP>The cases were as follows: two children 0-4 years of age, both with influenza B; one child 5-14 years of age with influenza B; two adults 45-64 years of age with influenza A(H3N2) and influenza A(unsubtyped); and one adult ≥65 years of age with influenza A(H1N1)pdm09. No ICU admissions or deaths were reported.
              To date this season, 13 influenza-associated hospitalizations have been reported, predominantly among children 0-4 years of age and adults 45-64 years of age (Table 6). There is no predominance of one influenza type or subtype among these cases to date. Consistent with the data from IMPACT and PCIRN-SOS, there is a greater proportion of cases of influenza B among children under 5 years of age compared to adults over 45 years of age. One ICU admission was reported in an adult 45-64 years of age and no deaths have been reported. It is important to note that the cause of death does not have to be attributable to influenza, a positive laboratory test is sufficient for reporting. Detailed clinical information (e.g. underlying medical conditions) is not known for these cases.
              * Note: Data from the Aggregate Surveillance System may also include cases reported by the IMPACT and PCIRN networks. Influenza-associated hospitalizations are not reported to PHAC by the following Provinces and Territory: BC, NU, QC, NS, and NB.

                Overall Summary
                • Influenza activity in Canada increased slightly in week 44.
                • Laboratory detections of influenza increased and ten regions reported sporadic influenza activity.
                • Both paediatric and adult hospitalizations with influenza were reported in week 44.
                • The ILI consultation rate declined slightly in week 44.
                Influenza/ILI Activity (geographic spread)

                In week 44, ten regions (in BC(2), AB(2), SK(1), ON(3) and QC(2)) reported sporadic activity (Figure 1). The number of regions reporting sporadic activity has increased over the past three weeks.
                Figure 1. Map of overall influenza/ILI activity level by province and territory, Canada, Week 44





                Note: Influenza/ILI activity levels, as represented on this map, are assigned and reported by Provincial and Territorial Ministries of Health, based on laboratory confirmations, sentinel ILI rates and reported outbreaks. Please refer to detailed definitions at the end of the report. Maps from previous weeks, including any retrospective updates, are available on the FluWatch website.

                Influenza and Other Respiratory Virus Detections

                The number of positive influenza tests increased for the second week in a row, from 21 in week 43 to 27 in week 44, bringing the percentage of positive influenza tests to 1.2%, driven predominantly by detections of influenza A (Figure 2). Cumulative influenza virus detections by type/subtype to date have been predominantly influenza A (76%) with more A(H1N1)pdm09 identified compared to A(H3) among those subtyped (Table 1). Detailed information on age and type/subtype has been received for 69 cases to date this season. The majority of cases have been adults 45-64 years of age (44%), followed by children under 5 years of age (23%) (Table 2).

                The number of positive tests for parainfluenza and RSV increased in week 44, although rhinovirus and parainfluenza remained the two predominant viruses detected (Figure 3).
                For more details, see the weekly Respiratory Virus Detections in Canada Report.

                Influenza Strain Characterizations

                During the 2013-2014 influenza season, the National Microbiology Laboratory (NML) has antigenically characterized nine influenza viruses [two A(H3N2), two A(H1N1)pdm09 and five influenza B]. Eight of the nine viruses were similar to the strains recommended by the WHO for the 2013-14 seasonal influenza vaccine; one influenza B virus was similar to the strain recommended by the WHO for the 2012-13 vaccine (Figure 4).
                Figure 4. Influenza strain characterizations, Canada, 2013-14, N = 9

                The NML receives a proportion of the number of influenza positive specimens from provincial laboratories for strain characterization and antiviral resistance testing. Characterization data reflect the results of haemagglutination inhibition (HAI) testing compared to the reference influenza strains recommended by WHO.
                The recommended components for the 2013-2014 northern hemisphere trivalent influenza vaccine include: an A/California/7/2009 (H1N1)pdm09-like virus, an A(H3N2) virus antigenically like the cell-propagated prototype virus A/Victoria/361/2011b, and a B/Massachusetts/2/2012-like virus (Yamagata lineage).

                Note: No data available for mean rate for weeks 19 to 39 for the 1996-1997 through 2002-2003 seasons. Delays in the reporting of data may cause data to change retrospectively. The calculation of the average ILI consultation rate over 17 seasons was aligned with influenza activity in each season. In BC, AB, and SK, data is compiled by a provincial sentinel surveillance program for reporting to FluWatch. The number of sentinel physicians in each province or territory is as follows: BC(21), AB(80), SK(11), MB(18), ON(169), QC(14), NB(29), NS(26), PE(4), NL(16), NU(1), NT(14), YT(13). Not all sentinel physicians report every week.

                Sentinel Hospital Influenza Surveillance

                Paediatric Influenza Hospitalizations and Deaths (IMPACT)
                In week 44, one laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalization was reported by the Immunization Monitoring Program Active (IMPACT) network: a child 2-4 years of age with influenza A(H1N1)pdm09 (Figure 8a).
                To date this season, a total of five influenza-associated paediatric hospitalizations have been reported by the IMPACT network: one child 0-5 months of age and four 2-4 years of age. One ICU admission was required in a child 2-4 years of age with influenza B. No deaths have been reported (Figure 9a and Table 4).
                Note: The number of hospitalizations reported through IMPACT represents a subset of all influenza-associated paediatric hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.
                Adult Influenza Hospitalizations and Deaths (PCIRN)
                Active surveillance of laboratory-confirmed influenza-associated adult (≥16 years of age) hospitalizations reported by the PHAC/CIHR Influenza Research Network (PCIRN) Serious Outcomes Surveillance (SOS) network will begin on November 15th 2013. The PCIRN-SOS network continues to report limited data on laboratory-confirmed cases of influenza identified through passive surveillance. One new hospitalization was reported in week 44, an adult ≥65 years of age with influenza A. No ICU admissions or deaths were reported in week 44 (Figure 8b).
                To date this season, six influenza-associated hospitalizations have been reported by the PCIRN-SOS network, all adults over 45 years of age with influenza A. ICU admission was required for one hospitalization and no deaths have been reported (Figure 9b and Table 5).
                Note: The number of hospitalizations reported through PCIRN represents a subset of all influenza-associated adult hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

                Provincial/Territorial Influenza Hospitalizations and Deaths

                In week 44, four new laboratory-confirmed influenza-associated hospitalizations were reported from participating provinces and territories.* The cases were as follows: two adults 45-64 years of age, both with influenza A(H3N2), and two adults ≥65 years of age with influenza A(H3N2) and influenza A(unsubtyped). No ICU admissions or deaths were reported.
                To date this season, 17 influenza-associated hospitalizations have been reported, of which 12 (70.6%) had influenza A (Table 6). Consistent with the data from IMPACT and PCIRN-SOS, there is a greater proportion of cases of influenza B among children under 5 years of age, whereas influenza A is predominant among adults over 45 years of age. One ICU admission was reported in an adult 45-64 years of age and no deaths have been reported. It is important to note that the cause of death does not have to be attributable to influenza, a positive laboratory test is sufficient for reporting. Detailed clinical information (e.g. underlying medical conditions) is not known for these cases.
                * Note: Data from the Aggregate Surveillance System may also include cases reported by the IMPACT and PCIRN networks. Influenza-associated hospitalizations are not reported to PHAC by the following Provinces and Territory: BC, NU, QC, NS, and NB. Only hospitalizations that require intensive medical care are reported by Saskatchewan. ICU admissions are not reported in Ontario.

                  Overall Summary
                  • Influenza activity in Canada continued to increase in week 45.
                  • Laboratory detections of influenza continued to increase, primarily influenza A.
                  • One influenza outbreak in a long-term care facility was reported in week 45, resulting in one region reporting localized influenza/ILI activity. An increasing number of regions reported sporadic activity.
                  • Both paediatric and adult hospitalizations with influenza continued to be reported in week 45.
                  • The ILI consultation rate has been stable over the past three weeks.
                  Influenza/ILI Activity (geographic spread)

                  In week 45, one region in Quebec reported localized activity and 16 regions (in BC(2), AB(3), SK(2), MB(2), ON(4), QC(2) and NL(1)) reported sporadic activity (Figure 1).
                  Figure 1. Map of overall influenza/ILI activity level by province and territory, Canada, Week 45





                  Note: Influenza/ILI activity levels, as represented on this map, are assigned and reported by Provincial and Territorial Ministries of Health, based on laboratory confirmations, sentinel ILI rates and reported outbreaks. Please refer to detailed definitions at the end of the report. Maps from previous weeks, including any retrospective updates, are available on the FluWatch website.

                  Influenza and Other Respiratory Virus Detections

                  The number of positive influenza tests increased for the third week in a row, from 27 in week 44 to 41 in week 45, bringing the percentage of positive influenza tests to 1.6%, driven predominantly by detections of influenza A (Figure 2). Cumulative influenza virus detections by type/subtype to date have been predominantly influenza A (80%) with more A(H1N1)pdm09 identified compared to A(H3) among those subtyped (Table 1). Detailed information on age and type/subtype has been received for 100 cases to date this season. Adults 45-64 years of age represent 37% of cases to date (Table 2).

                  The numbers of positive tests for parainfluenza, adenovirus and RSV have been increasing slowly in recent weeks. Rhinovirus and parainfluenza remained the two predominant viruses detected in week 45 (Figure 3).

                  Influenza Strain Characterizations

                  During the 2013-2014 influenza season, the National Microbiology Laboratory (NML) has antigenically characterized 11 influenza viruses [four A(H3N2), two A(H1N1)pdm09 and five influenza B]. Ten of the eleven viruses were similar to the strains recommended by the WHO for the 2013-14 seasonal influenza vaccine; one influenza B virus was similar to the strain recommended by the WHO for the 2011-12 vaccine (Figure 4).
                  Figure 4. Influenza strain characterizations, Canada, 2013-14, N = 11

                  The NML receives a proportion of the number of influenza positive specimens from provincial laboratories for strain characterization and antiviral resistance testing. Characterization data reflect the results of haemagglutination inhibition (HAI) testing compared to the reference influenza strains recommended by WHO.
                  The recommended components for the 2013-2014 northern hemisphere trivalent influenza vaccine include: an A/California/7/2009 (H1N1)pdm09-like virus, an A(H3N2) virus antigenically like the cell-propagated prototype virus A/Victoria/361/2011b, and a B/Massachusetts/2/2012-like virus (Yamagata lineage).

                  Influenza-like Illness (ILI) Consultation Rate

                  The national influenza-like-illness (ILI) consultation rate increased slightly from 17.2/1,000 in week 44 to 18.6/1,000 in week 45, but was similar to the previous two weeks (Figure 5).

                  Note: No data available for mean rate for weeks 19 to 39 for the 1996-1997 through 2002-2003 seasons. Delays in the reporting of data may cause data to change retrospectively. The calculation of the average ILI consultation rate over 17 seasons was aligned with influenza activity in each season. In BC, AB, and SK, data is compiled by a provincial sentinel surveillance program for reporting to FluWatch. The number of sentinel physicians in each province or territory is as follows: BC(21), AB(80), SK(11), MB(18), ON(169), QC(14), NB(29), NS(26), PE(4), NL(16), NU(1), NT(14), YT(13). Not all sentinel physicians report every week.

                  Sentinel Hospital Influenza Surveillance

                  Paediatric Influenza Hospitalizations and Deaths (IMPACT)
                  In week 45, two new laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalizations were reported by the Immunization Monitoring Program Active (IMPACT) network: two children 5-9 years of age, one with influenza A(H1N1)pdm09 and one with influenza B (Figure 8a).
                  To date this season, a total of seven influenza-associated paediatric hospitalizations have been reported by the IMPACT network (Table 4). One ICU admission was required in a child 2-4 years of age with influenza B. No deaths have been reported (Figure 9a).

                  Note: The number of hospitalizations reported through IMPACT represents a subset of all influenza-associated paediatric hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.
                  Adult Influenza Hospitalizations and Deaths (PCIRN)
                  Active surveillance of laboratory-confirmed influenza-associated adult (≥16 years of age) hospitalizations reported by the PHAC/CIHR Influenza Research Network (PCIRN) Serious Outcomes Surveillance (SOS) network will begin on November 15th 2013. The PCIRN-SOS network continues to report limited data on laboratory-confirmed cases of influenza identified through passive surveillance. Two new hospitalizations were reported in week 45, one adult 20-44 years of age and one 45-64 years of age, both with influenza A. No ICU admissions or deaths were reported in week 45 (Figure 8b).
                  To date this season, eight influenza-associated hospitalizations have been reported by the PCIRN-SOS network, all with influenza A. The majority have been adults over 45 years of age (Table 5). ICU admission was required for one hospitalization and no deaths have been reported (Figure 9b).

                  Note: The number of hospitalizations reported through PCIRN represents a subset of all influenza-associated adult hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

                  Provincial/Territorial Influenza Hospitalizations and Deaths

                  In week 45, five new laboratory-confirmed influenza-associated hospitalizations were reported from participating provinces and territories.* One case was reported in each of the following age-groups: 15-19 years, 20-44 years, 45-64 years; and two cases were ≥65 years of age. Four cases had influenza A(unsubtyped) and one had A(H1N1)pdm09. No ICU admissions or deaths were reported in week 45.
                  To date this season, 25 influenza-associated hospitalizations have been reported, of which 19 (76%) had influenza A (Table 6). Consistent with the data from IMPACT and PCIRN-SOS, there is a greater proportion of cases of influenza B among children under 5 years of age, whereas influenza A is predominant among adults over 45 years of age. Two ICU admissions have been reported in adults 45-64 years of age and no deaths have been reported. It is important to note that the cause of death does not have to be attributable to influenza, a positive laboratory test is sufficient for reporting. Detailed clinical information (e.g. underlying medical conditions) is not known for these cases.

                  * Note: Data from the Aggregate Surveillance System may also include cases reported by the IMPACT and PCIRN networks. Influenza-associated hospitalizations are not reported to PHAC by the following Provinces and Territory: BC, NU, QC, NS, and NB. Only hospitalizations that require intensive medical care are reported by Saskatchewan. ICU admissions are not reported in Ontario.

                    Overall Summary
                    • Influenza activity in Canada continued to increase for the fourth week in a row, indicating that the 2013-14 season has started.
                    • Laboratory detections of influenza continued to increase, primarily influenza A.
                    • Two influenza outbreaks in long-term care facilities were reported in week 46, and four regions reported localized influenza/ILI activity.
                    • Both paediatric and adult hospitalizations with influenza continued to be reported in week 46.
                    • The ILI consultation rate has been stable over the past four weeks.
                    Influenza/ILI Activity (geographic spread)

                    In week 46, three regions in ON(2) and QC(1) reported localized activity and 13 regions (in BC(1), AB(2), SK(1), ON(4), QC(4) and NB(1)) reported sporadic activity (Figure 1).
                    Figure 1. Map of overall influenza/ILI activity level by province and territory, Canada, Week 46





                    Note: Influenza/ILI activity levels, as represented on this map, are assigned and reported by Provincial and Territorial Ministries of Health, based on laboratory confirmations, sentinel ILI rates and reported outbreaks. Please refer to detailed definitions at the end of the report. Maps from previous weeks, including any retrospective updates, are available on the FluWatch website.

                    Influenza and Other Respiratory Virus Detections

                    The number of positive influenza tests continued to increase, from 42 in week 45 to 63 in week 46, bringing the percentage of positive influenza tests to 2.6%, driven predominantly by detections of influenza A (Figure 2). Cumulative influenza virus detections by type/subtype to date have been predominantly influenza A (81%) with more A(H1N1)pdm09 identified compared to A(H3) among those subtyped (Table 1). Detailed information on age and type/subtype has been received for 156 cases to date this season. Adults 45-64 years of age represent 36% of cases to date (Table 2).

                    In week 46, the number of positive tests for parainfluenza and RSV continued their slow increase. Despite an increasing number of tests performed, positive tests for rhinovirus have declined over the past five weeks. Rhinovirus and parainfluenza remained the two predominant viruses detected in week 46 (Figure 3).

                    Influenza Strain Characterizations

                    During the 2013-2014 influenza season, the National Microbiology Laboratory (NML) has antigenically characterized 20 influenza viruses [four A(H3N2), five A(H1N1)pdm09 and 11 influenza B]. Sixteen of the 20 viruses were similar to the strains recommended by the WHO for the 2013-14 seasonal influenza vaccine; four influenza B viruses were similar to the strain recommended by the WHO for the 2011-12 vaccine (Figure 4).
                    Figure 4. Influenza strain characterizations, Canada, 2013-14, N = 20

                    The NML receives a proportion of the number of influenza positive specimens from provincial laboratories for strain characterization and antiviral resistance testing. Characterization data reflect the results of haemagglutination inhibition (HAI) testing compared to the reference influenza strains recommended by WHO.
                    The recommended components for the 2013-2014 northern hemisphere trivalent influenza vaccine include: an A/California/7/2009 (H1N1)pdm09-like virus, an A(H3N2) virus antigenically like the cell-propagated prototype virus A/Victoria/361/2011b (e.g. A/Texas/50/2012), and a B/Massachusetts/2/2012-like virus (Yamagata lineage).

                    Antiviral Resistance

                    During the 2013-2014 influenza season, NML has tested 19 influenza viruses for resistance to oseltamivir and zanamivir, and all were sensitive. Eight influenza A viruses were tested for amantadine resistance, and all were resistant (Table 3).

                    Influenza-like Illness (ILI) Consultation Rate

                    The national influenza-like-illness (ILI) consultation rate decreased slightly from 19.9/1,000 in week 45 to 16.9/1,000 in week 46, but was similar to the previous three weeks (Figure 5).

                    Note: No data available for mean rate for weeks 19 to 39 for the 1996-1997 through 2002-2003 seasons. Delays in the reporting of data may cause data to change retrospectively. The calculation of the average ILI consultation rate over 17 seasons was aligned with influenza activity in each season. In BC, AB, and SK, data is compiled by a provincial sentinel surveillance program for reporting to FluWatch. The number of sentinel physicians in each province or territory is as follows: BC(21), AB(80), SK(11), MB(18), ON(169), QC(14), NB(29), NS(26), PE(4), NL(16), NU(1), NT(14), YT(13). Not all sentinel physicians report every week.

                    1 All provinces and territories except NU report outbreaks in long-term care facilities. All provinces and territories with the exception of NU and QC report outbreaks in hospitals. Outbreaks of influenza or influenza-like-illness in other facilities are reported to FluWatch but reporting varies between jurisdictions. Outbreak definitions are included at the end of the report.

                    Sentinel Hospital Influenza Surveillance

                    Paediatric Influenza Hospitalizations and Deaths (IMPACT)
                    In week 46, two new laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalizations were reported by the Immunization Monitoring Program Active (IMPACT) network: one child 2-4 years of age and one 10-16 years of age, both with influenza A(H1N1)pdm09 (Figure 8a).
                    To date this season, a total of 10 influenza-associated paediatric hospitalizations have been reported by the IMPACT network (Table 4). One ICU admission was required in a child 2-4 years of age with influenza B. No deaths have been reported (Figure 9a).

                    Note: The number of hospitalizations reported through IMPACT represents a subset of all influenza-associated paediatric hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.
                    Adult Influenza Hospitalizations and Deaths (PCIRN)
                    Active surveillance of laboratory-confirmed influenza-associated adult (≥16 years of age) hospitalizations reported by the PHAC/CIHR Influenza Research Network (PCIRN) Serious Outcomes Surveillance (SOS) network began on November 15th 2013. Two new hospitalizations were reported in week 46, both adults 20-44 years of age with influenza A. No ICU admissions or deaths were reported in week 46 (Figure 8b).
                    To date this season, 11 influenza-associated hospitalizations have been reported by the PCIRN-SOS network, all with influenza A. The majority (64%) have been adults over 45 years of age (Table 5). ICU admission was required for one hospitalization and no deaths have been reported (Figure 9b).

                    Note: The number of hospitalizations reported through PCIRN represents a subset of all influenza-associated adult hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

                    Provincial/Territorial Influenza Hospitalizations and Deaths

                    In week 46, seven new laboratory-confirmed influenza-associated hospitalizations were reported from participating provinces and territories.* The cases were as follows: one child 2-4 years, two adults 20-44 years, two adults 45-64 years and two adults ≥65 years of age. All cases had influenza A, four A(H1N1)pdm09 and three A(unsubtyped). One ICU admission was reported in a child 2-4 years of age with A(H1N1)pdm09. No deaths were reported.
                    To date this season, 36 influenza-associated hospitalizations have been reported, of which 30 (83%) had influenza A (Table 6). A greater proportion of cases under 20 years of age had influenza B (50%) compared to those 20 years of age or older (3.8%). Four ICU admissions have been reported this season, three in adults 45-64 years of age and one in a child 2-4 years of age, all with A(H1N1)pdm09. No deaths have been reported. It is important to note that the hospitalization or death does not have to be attributable to influenza, a positive laboratory test is sufficient for reporting. Detailed clinical information (e.g. underlying medical conditions) is not known for these cases.
                    * Note: Data from the Aggregate Surveillance System may also include cases reported by the IMPACT and PCIRN networks. Influenza-associated hospitalizations are not reported to PHAC by the following Provinces and Territory: BC, NU, QC, NS, and NB. Only hospitalizations that require intensive medical care are reported by Saskatchewan. ICU admissions are not reported in Ontario.

                      Overall Summary
                      • Influenza activity in Canada continued to increase in week 47, with a continuing predominance of influenza A.
                      • Three regions reported localized influenza/ILI activity and 20 reported sporadic activity.
                      • The ILI consultation rate increased after having been stable over the previous four weeks.
                      • The number of both paediatric and adult hospitalizations with influenza increased in week 47.
                      • Rhinovirus detections continued to decline while parainfluenza, RSV and adenovirus detections increased.

                      Influenza/ILI Activity (geographic spread)

                      In week 47, three regions in Ontario reported localized activity and 20 regions (in BC(4), AB(5), SK(2), MB(1), ON(3), and QC(5)) reported sporadic activity (Figure 1).
                      Figure 1. Map of overall influenza/ILI activity level by province and territory, Canada, Week 47





                      Note: Influenza/ILI activity levels, as represented on this map, are assigned and reported by Provincial and Territorial Ministries of Health, based on laboratory confirmations, sentinel ILI rates and reported outbreaks. Please refer to detailed definitions at the end of the report. Maps from previous weeks, including any retrospective updates, are available on the FluWatch website.

                      Influenza and Other Respiratory Virus Detections

                      The number of positive influenza tests continued to increase, from 59 in week 46 to 63 in week 47, bringing the percentage of positive influenza tests to 2.2% (Figure 2). Cumulative influenza virus detections by type/subtype to date have been predominantly influenza A (81%) with more A(H1N1)pdm09 identified compared to A(H3) among those subtyped (Table 1). Detailed information on age and type/subtype has been received for 243 cases to date this season. The proportion of cases by age-group is consistent with the expected pattern for seasonal influenza: 48% of laboratory detections were ≥45 years of age, and 19% were under 5 years of age. (Table 2).

                      Text equivalent for figure 2Number of positive influenza tests and percentage of tests positive, by type, subtype and report week, Canada, 2013-14
                      In week 47, the number of positive tests for parainfluenza, RSV and adenovirus continued their slow increase. Positive tests for rhinovirus continued to decline. Rhinovirus and parainfluenza remained the two predominant viruses detected in week 47 (Figure 3).
                      For more details, see the weekly Respiratory Virus Detections in Canada Report.

                      Influenza Strain Characterizations

                      During the 2013-2014 influenza season, the National Microbiology Laboratory (NML) has antigenically characterized 32 influenza viruses [four A(H3N2), 17 A(H1N1)pdm09 and 11 influenza B]. Twenty-eight (87.5%) viruses were similar to the strains recommended by the WHO for the 2013-14 seasonal influenza vaccine; four influenza B viruses were similar to the strain recommended by the WHO for the 2011-12 vaccine (Figure 4).
                      Figure 4. Influenza strain characterizations, Canada, 2013-14, N = 32

                      The NML receives a proportion of the number of influenza positive specimens from provincial laboratories for strain characterization and antiviral resistance testing. Characterization data reflect the results of haemagglutination inhibition (HAI) testing compared to the reference influenza strains recommended by WHO.
                      The recommended components for the 2013-2014 northern hemisphere trivalent influenza vaccine include: an A/California/7/2009 (H1N1)pdm09-like virus, an A(H3N2) virus antigenically like the cell-propagated prototype virus A/Victoria/361/2011b (e.g. A/Texas/50/2012), and a B/Massachusetts/2/2012-like virus (Yamagata lineage).

                      Antiviral Resistance

                      During the 2013-2014 influenza season, NML has tested 29 influenza viruses for resistance to oseltamivir and zanamivir, and all were sensitive. Thirteen influenza A viruses were tested for amantadine resistance, and all were resistant (Table 3).

                      Influenza-like Illness (ILI) Consultation Rate

                      The national influenza-like-illness (ILI) consultation rate increased from 16.1/1,000 in week 46 to 24.3/1,000 in week 47, following an upwards trend in keeping with other surveillance indicators (Figure 5).
                      Figure 5. Influenza-like-illness (ILI) consultation rates by report week, compared to the 1996-97 through to 2012-13 seasons (with pandemic data suppressed), Canada, 2013-2014
                      Note: No data available for mean rate for weeks 19 to 39 for the 1996-1997 through 2002-2003 seasons. Delays in the reporting of data may cause data to change retrospectively. The calculation of the average ILI consultation rate over 17 seasons was aligned with influenza activity in each season. In BC, AB, and SK, data is compiled by a provincial sentinel surveillance program for reporting to FluWatch. The number of sentinel physicians in each province or territory is as follows: BC(21), AB(80), SK(11), MB(18), ON(169), QC(14), NB(29), NS(26), PE(4), NL(16), NU(1), NT(14), YT(13). Not all sentinel physicians report every week.

                      Influenza Outbreak Surveillance

                      One new influenza outbreak in a long-term care facility was reported in week 47 (Figure 6).

                      1 All provinces and territories except NU report outbreaks in long-term care facilities. All provinces and territories with the exception of NU and QC report outbreaks in hospitals. Outbreaks of influenza or influenza-like-illness in other facilities are reported to FluWatch but reporting varies between jurisdictions. Outbreak definitions are included at the end of the report.

                      Sentinel Hospital Influenza Surveillance

                      Paediatric Influenza Hospitalizations and Deaths (IMPACT)
                      In week 47, six new laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalizations were reported by the Immunization Monitoring Program Active (IMPACT) network: two children in each of the age-groups 2-4 years, 5-9 years, and 10-16 years of age. Four cases had influenza A and two had influenza B (Figure 8a).
                      To date this season, a total of 19 influenza-associated paediatric hospitalizations have been reported by the IMPACT network (Table 4). Two ICU admissions were reported, both in children 2-4 years of age, one with influenza A(H1N1)pdm09 and one with influenza B. No deaths have been reported (Figure 9a).

                      Note: The number of hospitalizations reported through IMPACT represents a subset of all influenza-associated paediatric hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.
                      Adult Influenza Hospitalizations and Deaths (PCIRN)
                      Active surveillance of laboratory-confirmed influenza-associated adult (≥16 years of age) hospitalizations reported by the PHAC/CIHR Influenza Research Network (PCIRN) Serious Outcomes Surveillance (SOS) network began on November 15th 2013. Five new hospitalizations were reported in week 47, two cases 45-64 years of age and three ≥65 years of age, all with influenza A. No ICU admissions or deaths were reported in week 47 (Figure 8b).
                      To date this season, 16 influenza-associated hospitalizations have been reported by the PCIRN-SOS network, all with influenza A. The majority (75%) have been adults over 45 years of age (Table 5). ICU admission was required for one hospitalization and no deaths have been reported (Figure 9b).

                      Note: The number of hospitalizations reported through PCIRN represents a subset of all influenza-associated adult hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

                      Provincial/Territorial Influenza Hospitalizations and Deaths

                      In week 47, 21 new laboratory-confirmed influenza-associated hospitalizations were reported from participating provinces and territories.<SUP style="LINE-HEIGHT: 0.65em">*</SUP>Among these cases, ten (48%) were adults ≥45 years of age, and five (24%) were children <2 years of age. Twenty cases had influenza A, of which 65% were A(H1N1)pdm09. No ICU admissions or deaths were reported.
                      To date this season, 57 influenza-associated hospitalizations have been reported, of which 50 (88%) had influenza A (Table 6). The majority of cases (56%) were ≥45 years of age, and 23% were under 5 years of age. A greater proportion of cases under 20 years of age had influenza B (29%) compared to those 20 years of age or older (5%). Four ICU admissions have been reported this season, three in adults 45-64 years of age and one in a child 2-4 years of age, all with A(H1N1)pdm09. No deaths have been reported. It is important to note that the hospitalization or death does not have to be attributable to influenza, a positive laboratory test is sufficient for reporting. Detailed clinical information (e.g. underlying medical conditions) is not known for these cases.
                      Note: Influenza-associated hospitalizations are not reported to PHAC by the following Provinces and Territory: BC, NU, QC, NS, and NB. Only hospitalizations that require intensive medical care are reported by Saskatchewan. ICU admissions are not distinguished among hospital admissions reported from Ontario. The number of new influenza-associated hospitalizations and deaths reported for the current week may include cases from Ontario that occurred in previous weeks, as a result of retrospective updates to the cumulative total. Data may also include cases reported by the IMPACT and PCIRN networks.

                        Overall Summary
                        • Influenza activity in Canada continued to increase in week 48.
                        • Influenza A remained the predominant influenza virus type, with 77% of subtyped influenza A specimens to date identified as A(H1N1)pdm09.
                        • Two regions reported localized influenza/ILI activity and 18 reported sporadic activity, and the ILI consultation rate continued to increase.
                        • The number of both paediatric and adult hospitalizations with influenza increased in week 48.
                        • RSV detections increased sharply in week 48, although rhinovirus remained the predominant virus detected.
                        Influenza/ILI Activity (geographic spread)

                        In week 48, two regions in Ontario reported localized activity and 18 regions (in BC(3), AB(4), SK(1), ON(4), and QC(6)) reported sporadic activity (Figure 1).

                        Note: Influenza/ILI activity levels, as represented on this map, are assigned and reported by Provincial and Territorial Ministries of Health, based on laboratory confirmations, sentinel ILI rates and reported outbreaks. Please refer to detailed definitions at the end of the report. Maps from previous weeks, including any retrospective updates, are available on the FluWatch website.

                        The number of positive influenza tests increased sharply, from 65 in week 47 to 114 in week 48, bringing the percentage of positive influenza tests to 3.7% (Figure 2). Cumulative influenza virus detections by type/subtype to date have been predominantly influenza A (84%) with more A(H1N1)pdm09 identified compared to A(H3) among those subtyped (Table 1). Detailed information on age and type/subtype has been received for 382 cases to date this season. The proportion of positive laboratory specimens by age-group is consistent with the expected pattern for seasonal influenza: 47% of laboratory detections were ≥45 years of age, and 20% were under 5 years of age. (Table 2).

                        In week 48, the number of positive tests for RSV increased sharply; detections of adenovirus and human metapneumovirus continued a slow increase; and detections of parainfluenza declined. Positive tests for rhinovirus continued to decline. Rhinovirus remained the predominant virus detected in week 48 (Figure 3).

                        Influenza Strain Characterizations

                        During the 2013-2014 influenza season, the National Microbiology Laboratory (NML) has antigenically characterized 57 influenza viruses [6 A(H3N2), 35 A(H1N1)pdm09 and 16 influenza B]. Fifty-two (91.2%) viruses were similar to the strains recommended by the WHO for the 2013-14 seasonal influenza vaccine; five influenza B viruses were similar to the strain recommended by the WHO for the 2011-12 vaccine (Figure 4).
                        Figure 4. Influenza strain characterizations, Canada, 2013-14, N = 57

                        The NML receives a proportion of the number of influenza positive specimens from provincial laboratories for strain characterization and antiviral resistance testing. Characterization data reflect the results of haemagglutination inhibition (HAI) testing compared to the reference influenza strains recommended by WHO.
                        The recommended components for the 2013-2014 northern hemisphere trivalent influenza vaccine include: an A/California/7/2009 (H1N1)pdm09-like virus, an A(H3N2) virus antigenically like the cell-propagated prototype virus A/Victoria/361/2011b (e.g. A/Texas/50/2012), and a B/Massachusetts/2/2012-like virus (Yamagata lineage).

                        Note: No data available for mean rate for weeks 19 to 39 for the 1996-1997 through 2002-2003 seasons. Delays in the reporting of data may cause data to change retrospectively. The calculation of the average ILI consultation rate over 17 seasons was aligned with influenza activity in each season. In BC, AB, and SK, data is compiled by a provincial sentinel surveillance program for reporting to FluWatch. The number of sentinel physicians in each province or territory is as follows: BC(21), AB(80), SK(11), MB(18), ON(169), QC(14), NB(29), NS(26), PE(4), NL(16), NU(1), NT(14), YT(13). Not all sentinel physicians report every week.

                        Influenza Outbreak Surveillance

                        No new influenza outbreaks were reported in week 48 (Figure 6).

                        1 All provinces and territories except NU report outbreaks in long-term care facilities. All provinces and territories with the exception of NU and QC report outbreaks in hospitals. Outbreaks of influenza or influenza-like-illness in other facilities are reported to FluWatch but reporting varies between jurisdictions. Outbreak definitions are included at the end of the report.

                        Sentinel Hospital Influenza Surveillance

                        Paediatric Influenza Hospitalizations and Deaths (IMPACT)
                        In week 48, nine new laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalizations were reported by the Immunization Monitoring Program Active (IMPACT) network: all cases of influenza A (four A(H1N1)pdm09 and five A(unsubtyped)). Four cases were children under 6 months of age, two cases were 6-23 months of age, and three cases were 2-9 years of age (Figure 8a).
                        To date this season, a total of 28 influenza-associated paediatric hospitalizations have been reported by the IMPACT network (Table 4). Two ICU admissions were reported, both in children 2-4 years of age, one with influenza A(H1N1)pdm09 and one with influenza B. No deaths have been reported (Figure 9a).

                        Note: The number of hospitalizations reported through IMPACT represents a subset of all influenza-associated paediatric hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.
                        Adult Influenza Hospitalizations and Deaths (PCIRN)
                        In week 48, eight new laboratory-confirmed influenza-associated adult (≥16 years of age) hospitalizations were reported through active surveillance by the PHAC/CIHR Influenza Research Network (PCIRN) Serious Outcomes Surveillance (SOS) network: two cases 20-44 years of age, two cases 45-64 years of age and four ≥65 years of age. Influenza A was identified in all cases: four A(H1N1)pdm09, one A(H3N2) and three A(unsubtyped). No ICU admissions or deaths were reported in week 48 (Figure 8b).
                        To date this season, 24 influenza-associated hospitalizations have been reported by the PCIRN-SOS network, all with influenza A. The majority (75%) have been adults over 45 years of age (Table 5). ICU admission was required for one hospitalization and no deaths have been reported (Figure 9b).

                        Note: The number of hospitalizations reported through PCIRN represents a subset of all influenza-associated adult hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

                        Provincial/Territorial Influenza Hospitalizations and Deaths

                        In week 48, 11 new laboratory-confirmed influenza-associated hospitalizations were reported from participating provinces and territories.<SUP>*</SUP> The cases were as follows: two children less than 6 months of age, one child 6-23 months, two children 5-14 years, three adults 20-44 years, two adults 45-64 years and one adult ≥65 years of age. All cases were influenza A, of which six were A(H1N1)pdm09 and five A(unsubtyped). No ICU admissions or deaths were reported.
                        To date this season, 68 influenza-associated hospitalizations have been reported, of which 61 (90%) had influenza A (Table 6). More than half of cases (52%) were ≥45 years of age, and 24% were under 5 years of age. A greater proportion of cases under 20 years of age had influenza B (22%) compared to those 20 years of age or older (4%). Five ICU admissions have been reported this season, four in adults 45-64 years of age and one in a child 2-4 years of age, all with A(H1N1)pdm09. One death has been reported in an adult 45-64 years of age with A(H1N1)pdm09. It is important to note that the hospitalization or death does not have to be attributable to influenza, a positive laboratory test is sufficient for reporting. Detailed clinical information (e.g. underlying medical conditions) is not known for these cases.
                        Note: Influenza-associated hospitalizations are not reported to PHAC by the following Provinces and Territory: BC, NU, QC, NS, and NB. Only hospitalizations that require intensive medical care are reported by Saskatchewan. ICU admissions are not distinguished among hospital admissions reported from Ontario. The number of new influenza-associated hospitalizations and deaths reported for the current week may include cases from Ontario that occurred in previous weeks, as a result of retrospective updates to the cumulative total. Data may also include cases reported by the IMPACT and PCIRN networks.

                          Overall Summary
                          • Influenza activity in Canada continued to increase in week 49 with three regions reporting localized influenza/ILI activity and 23 reporting sporadic activity.
                          • Influenza A remains the predominant influenza virus type this season (87%), and among subtyped influenza A specimens, 83% were A(H1N1)pdm09.
                          • The number of both paediatric and adult hospitalizations with influenza continued to increase; 97% of adult cases and 76% of paediatric cases from sentinel hospital surveillance were influenza A, predominantly A(H1N1)pdm09.
                          • RSV detections continued to increase, and RSV was the most frequently detected respiratory virus in week 49.
                          Influenza/ILI Activity (geographic spread)

                          In week 49, two regions in Ontario and one in Quebec reported localized activity and 23 regions (in BC(5), AB(4), SK(3), MB(1), ON(5), QC(4) and YT(1)) reported sporadic activity (Figure 1).

                          Note: Influenza/ILI activity levels, as represented on this map, are assigned and reported by Provincial and Territorial Ministries of Health, based on laboratory confirmations, sentinel ILI rates and reported outbreaks. Please refer to detailed definitions at the end of the report. Maps from previous weeks, including any retrospective updates, are available on the FluWatch website.

                          Influenza and Other Respiratory Virus Detections

                          The number of positive influenza tests increased sharply, from 115 in week 48 to 200 in week 49, bringing the percentage of positive influenza tests to 6.1% (Figure 2). Cumulative influenza virus detections to date have been predominantly influenza A (87%). Among subtyped influenza A viruses, 83% (317/381) were A(H1N1)pdm09 (Table 1). Detailed information on age and type/subtype has been received for 619 cases to date this season. Consistent with demographics observed in recent seasons, a larger proportion of cases of A(H3N2) and influenza B were ≥65 years of age (37.5% and 38.1%, respectively) compared to cases of A(H1N1)pdm09 (9.0%).

                          In week 49, the number of positive tests for RSV continued to increase. Positive tests for rhinovirus continued to decline. RSV was the most frequently detected virus in week 49, followed by rhinovirus and parainfluenza (Figure 3).
                          For more details, see the weekly Respiratory Virus Detections in Canada Report.

                          Influenza Strain Characterizations

                          During the 2013-2014 influenza season, the National Microbiology Laboratory (NML) has antigenically characterized 82 influenza viruses [12 A(H3N2), 46 A(H1N1)pdm09 and 24 influenza B]. Seventy-seven (93.9%) viruses were similar to the strains recommended by the WHO for the 2013-14 seasonal influenza vaccine; five influenza B viruses were similar to the strain recommended by the WHO for the 2011-12 vaccine (Figure 4).
                          Figure 4. Influenza strain characterizations, Canada, 2013-14, N = 82

                          The NML receives a proportion of the number of influenza positive specimens from provincial laboratories for strain characterization and antiviral resistance testing. Characterization data reflect the results of haemagglutination inhibition (HAI) testing compared to the reference influenza strains recommended by WHO.
                          The recommended components for the 2013-2014 northern hemisphere trivalent influenza vaccine include: an A/California/7/2009 (H1N1)pdm09-like virus, an A(H3N2) virus antigenically like the cell-propagated prototype virus A/Victoria/361/2011b (e.g. A/Texas/50/2012), and a B/Massachusetts/2/2012-like virus (Yamagata lineage).

Delays in the reporting of data may cause data to change retrospectively. The calculation of the average ILI consultation rate over 17 seasons was aligned with influenza activity in each season. In BC, AB, and SK, data is compiled by a provincial sentinel surveillance program for reporting to FluWatch. The number of sentinel physicians in each province or territory is as follows: BC(21), AB(80), SK(11), MB(18), ON(169), QC(14), NB(29), NS(26), PE(4), NL(16), NU(1), NT(14), YT(13). Not all sentinel physicians report every week.

                          Paediatric Influenza Hospitalizations and Deaths (IMPACT)
                          In week 49, ten new laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalizations were reported by the Immunization Monitoring Program Active (IMPACT) network. All were cases of influenza A: seven A(H1N1)pdm09 and three A(unsubtyped). One case was a child under 6 months of age, two were 6-23 months of age, two were 2-4 years of age, three were 5-9 years of age and two was 10-16 years of age (Figure 8a). One ICU admission was reported in week 49, a child 10-16 years of age with A(H1N1)pdm09.
                          To date this season, a total of 38 influenza-associated paediatric hospitalizations have been reported by the IMPACT network, the majority of which have been influenza A (Table 4). Twelve (31.6%) of cases have been children under 2 years of age. Three ICU admissions have been reported, two children 2-4 years of age, one with influenza A(H1N1)pdm09 and one with influenza B; and one child 10-16 years of age with A(H1N1)pdm09. No deaths have been reported (Figure 9a).

                          Note: The number of hospitalizations reported through IMPACT represents a subset of all influenza-associated paediatric hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.
                          Adult Influenza Hospitalizations and Deaths (PCIRN)
                          In week 49, seven new laboratory-confirmed influenza-associated adult (≥16 years of age) hospitalizations were reported through active* surveillance by the PHAC/CIHR Influenza Research Network (PCIRN) Serious Outcomes Surveillance (SOS) network: five cases 45-64 years of age and two ≥65 years of age. Influenza A was identified in six cases: three A(H1N1)pdm09 and three A(unsubtyped). One ICU admission was reported in an adult 45-64 years of age with A(H1N1)pdm09 (Figure 8b).
                          To date this season, 29 influenza-associated hospitalizations have been reported by the PCIRN-SOS network, 28 with influenza A. The majority (79.3%) have been adults over 45 years of age (Table 5). ICU admission was required for two hospitalizations, both adults 45-64 years of age. No deaths have been reported (Figure 9b).

                          Note: PCIRN-SOS conducted passive surveillance from April 30th to November 14th, 2013. Cases reported during this period were identified by laboratory detection of influenza among patients admitted to participating hospitals. Active surveillance began November 15th during which time PCIRN site coordinators investigate cases potentially related to influenza. Data from both active and passive surveillance reported during the 2013-14 season are included in this report. The number of hospitalizations reported through PCIRN represents a subset of all influenza-associated adult hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

                          Provincial/Territorial Influenza Hospitalizations and Deaths

                          In week 49, 37 new laboratory-confirmed influenza-associated hospitalizations were reported from participating provinces and territories.* The cases were as follows: two children less than 6 months of age, two children 6-23 months, three children 2-4 years, four children 5-14 years, six adults 20-44 years, thirteen adults 45-64 years and seven adults ≥65 years of age. All cases were influenza A, of which 22 were A(H1N1)pdm09, one A(H3N2) and 14 A(unsubtyped). Two ICU admissions were reported: one child 5-14 years with A(H1N1)pdm09 and one adult ≥65 years of age with A(unsubtyped). One death was reported in an adult ≥65 years of age with A(H1N1)pdm. The number of new influenza-associated hospitalizations and deaths reported for the current week may include cases from Ontario that occurred in previous weeks, as a result of retrospective updates to the cumulative total.
                          To date this season, 107 influenza-associated hospitalizations have been reported, of which 100 (93.5%) had influenza A and among those 57% were A(H1N1)pdm09 (Table 6). More than half of cases (51.4%) were ≥45 years of age, and 21.5% were under 5 years of age. A greater proportion of cases under 20 years of age had influenza B (14%) compared to those 20 years of age or older (3%). Eight ICU admissions have been reported this season, all cases of influenza A (seven A(H1N1)pdm09 and one A(unsubtyped). The cases were as follows: one child 2-4 years of age, one 5-14 years of age, one adult 20-44 years of age, four adults 45-64 years of age and one adult ≥65 years of age. Two deaths have been reported: one adult 45-64 years of age and one ≥65 years of age, both with A(H1N1)pdm09. It is important to note that the hospitalization or death does not have to be attributable to influenza, a positive laboratory test is sufficient for reporting. Detailed clinical information (e.g. underlying medical conditions) is not known for these cases.
                          * Note: Influenza-associated hospitalizations are not reported to PHAC by the following Provinces and Territory: BC, NU, QC, NS, and NB. Only hospitalizations that require intensive medical care are reported by Saskatchewan. ICU admissions are not distinguished among hospital admissions reported from Ontario. Data may also include cases reported by the IMPACT and PCIRN networks.

                            Overall Summary
                            • Influenza activity in Canada continued to increase in week 50. The number of regions that reported sporadic or localized influenza/ILI activity increased, with activity reported in 8 of the 10 provinces.
                            • Influenza A(H1N1)pdm09 remains the predominant influenza virus type this season.
                            • The number of paediatric hospitalizations with influenza continued to increase, while adult hospitalizations decreased slightly in week 50; 98% of adult cases and 81% of paediatric cases from sentinel hospital surveillance were influenza A, predominantly A(H1N1)pdm09.
                            Note: The FluWatch report will not be published on Friday, December 27th, 2013. A combined report for weeks 51 and 52 will be published on Friday, January 3rd, 2014.

                            Influenza/ILI Activity (geographic spread)

                            In week 50, four regions (in AB(1), ON(2) and QC(1)) reported localized activity and 25 regions (in BC(5), AB(4), SK(3), MB(1), ON(5), QC(4), NS(1), and NL(2)) reported sporadic activity (Figure 1).

                            Note: Influenza/ILI activity levels, as represented on this map, are assigned and reported by Provincial and Territorial Ministries of Health, based on laboratory confirmations, sentinel ILI rates and reported outbreaks. Please refer to detailed definitions at the end of the report. Maps from previous weeks, including any retrospective updates, are available on the FluWatch website.

                            Influenza and Other Respiratory Virus Detections

                            The number of positive influenza tests increased sharply, from 211 in week 49 to 367 in week 50, bringing the percentage of positive influenza tests to 9.6% (Figure 2). Cumulative influenza virus detections to date have been predominantly influenza A (89%). Among subtyped influenza A viruses, 88% (545/619) were A(H1N1)pdm09 (Table 1). Detailed information on age and type/subtype has been received for 909 cases to date this season. Consistent with demographics observed in recent seasons, a larger proportion of cases of A(H3N2) and influenza B were ≥65 years of age (32.7% and 37.5%, respectively) compared to cases of A(H1N1)pdm09 (15.3%).

                            In week 50, the number of positive tests for RSV continued to increase sharply. RSV was the second most frequently detected virus in week 50, after influenza; and followed by parainfluenza (Figure 3).
                            For more details, see the weekly Respiratory Virus Detections in Canada Report.

                            Influenza Strain Characterizations

                            During the 2013-2014 influenza season, the National Microbiology Laboratory (NML) has antigenically characterized 117 influenza viruses [14 A(H3N2), 79 A(H1N1)pdm09 and 24 influenza B]. The vast majority (95.7%) of viruses were similar to the strains recommended by the WHO for the 2013-14 seasonal influenza vaccine; five influenza B viruses were similar to the strain recommended by the WHO for the 2011-12 vaccine (Figure 4).
                            Figure 4. Influenza strain characterizations, Canada, 2013-14, N = 117

                            The NML receives a proportion of the number of influenza positive specimens from provincial laboratories for strain characterization and antiviral resistance testing. Characterization data reflect the results of haemagglutination inhibition (HAI) testing compared to the reference influenza strains recommended by WHO.
                            The recommended components for the 2013-2014 northern hemisphere trivalent influenza vaccine include: an A/California/7/2009 (H1N1)pdm09-like virus, an A(H3N2) virus antigenically like the cell-propagated prototype virus A/Victoria/361/2011b (e.g. A/Texas/50/2012), and a B/Massachusetts/2/2012-like virus (Yamagata lineage).

Delays in the reporting of data may cause data to change retrospectively. The calculation of the average ILI consultation rate over 17 seasons was aligned with influenza activity in each season. In BC, AB, and SK, data is compiled by a provincial sentinel surveillance program for reporting to FluWatch. The number of sentinel physicians in each province or territory is as follows: BC(21), AB(80), SK(11), MB(18), ON(169), QC(14), NB(29), NS(26), PE(4), NL(16), NU(1), NT(14), YT(13). Not all sentinel physicians report every week.

                            Paediatric Influenza Hospitalizations and Deaths (IMPACT)
                            In week 50, 14 new laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalizations were reported by the Immunization Monitoring Program Active (IMPACT) network. Thirteen were cases of influenza A: five A(H1N1)pdm09 and eight A(unsubtyped). Three cases were children under 6 months of age, two were 6-23 months of age, five were 2-4 years of age, one was 5-9 years of age and three were 10-16 years of age (Figure 8a). Two ICU admissions were reported in week 50, one child 5-9 years of age with influenza B, and one 10-16 years of age with A(H1N1)pdm09.
                            To date this season, a total of 53 influenza-associated paediatric hospitalizations have been reported by the IMPACT network, the majority of which have been influenza A (Table 4). Eighteen (34%) of cases have been children under 2 years of age. Five ICU admissions have been reported: two cases with influenza B and three with A(H1N1)pdm09, all children 2 years of age or older. No deaths have been reported (Figure 9a).

                            Note: The number of hospitalizations reported through IMPACT represents a subset of all influenza-associated paediatric hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

Influenza A was identified in eight cases: four A(H1N1)pdm09 and four A(unsubtyped). One ICU admission was reported in an adult ≥65 years of age with A(unsubtyped) (Figure 8b).
                            To date this season, 41 influenza-associated hospitalizations have been reported by the PCIRN-SOS network, 40 with influenza A. The majority (78%) have been adults over 45 years of age (Table 5). ICU admission was required for three hospitalizations, all adults 45-64 years of age with influenza A. No deaths have been reported (Figure 9b).

                            Note: PCIRN-SOS conducted passive surveillance from April 30th to November 14th, 2013. Cases reported during this period were identified by laboratory detection of influenza among patients admitted to participating hospitals. Active surveillance began November 15th during which time PCIRN site coordinators investigate cases potentially related to influenza. Data from both active and passive surveillance reported during the 2013-14 season are included in this report. The number of hospitalizations reported through PCIRN represents a subset of all influenza-associated adult hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

                            Provincial/Territorial Influenza Hospitalizations and Deaths

                            In week 50, 68 new laboratory-confirmed influenza-associated hospitalizations were reported from participating provinces and territories.*The cases were as follows: five children less than 6 months of age, three children 6-23 months, eight children 2-4 years, four children 5-14 years, 11 adults 20-44 years, 22 adults 45-64 years and 15 adults ≥65 years of age. All but two were cases of influenza A, of which 39 were A(H1N1)pdm09, one was A(H3N2) and 26 A(unsubtyped). No ICU admissions were reported. Three deaths were reported in adults 45-64 years of age with influenza A. The number of new influenza-associated hospitalizations and deaths reported for the current week may include cases from Ontario that occurred in previous weeks, as a result of retrospective updates to the cumulative total.
                            To date this season, 161 influenza-associated hospitalizations have been reported, of which 152 (94.4%) had influenza A and among those 57% were A(H1N1)pdm09 (Table 6). More than half of cases (52.8%) were ≥45 years of age, and 23.6% were under 5 years of age. A greater proportion of cases under 20 years of age had influenza B (12%) compared to those 20 years of age or older (3%). Eight ICU admissions have been reported this season, all cases of influenza A (seven A(H1N1)pdm09 and one A(unsubtyped)). The cases were as follows: one child 2-4 years of age, one 5-14 years of age, one adult 20-44 years of age, four adults 45-64 years of age and one adult ≥65 years of age. Five deaths have been reported: four adults 45-64 years of age and one ≥65 years of age, all with A(H1N1)pdm09. It is important to note that the hospitalization or death does not have to be attributable to influenza, a positive laboratory test is sufficient for reporting. Detailed clinical information (e.g. underlying medical conditions) is not known for these cases.
                            * Note: Influenza-associated hospitalizations are not reported to PHAC by the following Provinces and Territory: BC, NU, QC, NS, and NB. Only hospitalizations that require intensive medical care are reported by Saskatchewan. ICU admissions are not distinguished among hospital admissions reported from Ontario. Data may also include cases reported by the IMPACT and PCIRN networks.

                              Overall Summary
                              • Influenza activity in Canada continued to increase sharply in weeks 51 and 52 with increases in laboratory detections of influenza, ILI consultations, hospitalizations with influenza and prescriptions for influenza antivirals.
                              • Influenza A has been identified in >90% of cases this season, and A(H1N1)pdm09 remains the predominant subtype, representing approximately 90% of subtyped influenza viruses.
                              • A greater proportion of cases have been reported among adults 20-64 years of age compared to those ≥65 years of age, which is a change from the demographics of the 2012-13 season when A(H3N2) was predominant.
                              Influenza/ILI Activity (geographic spread)

                              In weeks 51 and 52, the same two regions in Alberta reported widespread activity. In week 51, three regions in Ontario reported localized activity and in week 52 six regions (in SK(1), ON(4), and NT(1)) reported localized activity (Figure 1). However, no data was received for 20 regions in each of weeks 51 and 52.

                              Influenza and Other Respiratory Virus Detections

                              The number of positive influenza tests continued to increase in weeks 51 and 52, from 382 in week 50 to 754 in week 51 and 1152 in week 52. The percentage of positive influenza tests increased to 17.3% in week 51 and 23.6% in week 52 (Figure 2). Cumulative influenza virus detections to date have been predominantly influenza A (94%). Among subtyped influenza A viruses, 94% (1731/1843) were A(H1N1)pdm09 (Table 1). Detailed information on age and type/subtype has been received for 2,819 cases to date this season. A significantly greater proportion of laboratory detections of influenza have been reported in adults 20-64 years of age compared to those ≥65 years of age this season compared to the 2012-13 season (Table 2). This is expected given the predominance of A(H1N1)pdm09 this season compared to 2012-13 when A(H3N2) was the dominant circulating subtype.

                              In weeks 51 and 52, the number of positive tests for RSV was stable. RSV was the second most frequently detected virus in week 52, after influenza. The number of positive tests for rhinovirus and parainfluenza decreased during this 2-week period, while detections of adenovirus, coronvirus and human metapneumovirus increased (Figure 3).
                              For more details, see the weekly Respiratory Virus Detections in Canada Report.

                              Influenza Strain Characterizations

                              During the 2013-2014 influenza season, the National Microbiology Laboratory (NML) has antigenically characterized 155 influenza viruses [17 A(H3N2), 112 A(H1N1)pdm09 and 26 influenza B]. The vast majority (96.8%) of viruses were similar to the strains recommended by the WHO for the 2013-14 seasonal influenza vaccine. Two A(H1N1)pdm09 viruses showed reduced titres to antiserum against the reference A/California/07/2009 strain. Five influenza B viruses were similar to the strain recommended by the WHO for the 2011-12 vaccine (Figure 4).
                              Figure 4. Influenza strain characterizations, Canada, 2013-14, N = 155

                              The NML receives a proportion of the number of influenza positive specimens from provincial laboratories for strain characterization and antiviral resistance testing. Characterization data reflect the results of haemagglutination inhibition (HAI) testing compared to the reference influenza strains recommended by WHO.
                              The recommended components for the 2013-2014 northern hemisphere trivalent influenza vaccine include: an A/California/7/2009 (H1N1)pdm09-like virus, an A(H3N2) virus antigenically like the cell-propagated prototype virus A/Victoria/361/2011b (e.g. A/Texas/50/2012), and a B/Massachusetts/2/2012-like virus (Yamagata lineage).

                              Influenza-like Illness (ILI) Consultation Rate

                              The national influenza-like-illness (ILI) consultation rate jumped to 60.0/1,000 in week 50, returning to 37.0/1,000 in week 51 and increasing to 42.6/1,000 in week 52 (Figure 5).

                              Note: No data available for mean rate for weeks 19 to 39 for the 1996-1997 through 2002-2003 seasons. Delays in the reporting of data may cause data to change retrospectively. The calculation of the average ILI consultation rate over 17 seasons was aligned with influenza activity in each season. In BC, AB, and SK, data is compiled by a provincial sentinel surveillance program for reporting to FluWatch. The number of sentinel physicians in each province or territory is as follows: BC(21), AB(80), SK(11), MB(18), ON(169), QC(14), NB(29), NS(26), PE(4), NL(16), NU(1), NT(14), YT(13). Not all sentinel physicians report every week.

                              In week 51, three new influenza outbreaks were reported: one in a long-term care facility and two in hospitals. Three additional ILI outbreaks in other facilities or communities were also reported. In week 52, ten new influenza outbreaks were reported: eight in long-term care facilities and two in hospitals (Figure 6).

                              The number of prescriptions for influenza antivirals followed a trend consistent compared with previous seasons and other indicators of influenza circulation. The largest number of antiviral prescriptions is among adults 19-64 years of age, which is in keeping with the wide age range of this group as well as the age-distribution observed among laboratory detections and hospitalizations during the season to date (Figure 7).

                              Note: Pharmacy sales data are provided to the Public Health Agency of Canada by Rx Canada Inc. and sourced from major retail drug chains representing over 3,000 stores nationwide (excluding Nunavut) in 85% of Health Regions. A delay in data reported from one retailer which provides approximately 50% of the national volume of prescriptions affects the data for the current and previous week. Data from Ontario, Saskatchewan and the Territories is most influenced by this delay.

                              Paediatric Influenza Hospitalizations and Deaths (IMPACT)

                              The number of new laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalizations reported by the Immunization Monitoring Program Active (IMPACT) network continued to increase from 14 in week 50 to 37 in week 51 and 50 in week 52. Among these 87 cases, 85 (97.7%) had influenza A, and of these 38 (44.7%) were A(H1N1)pdm09, one (1.2%) A(H3N2) and 46 (54.1%) A(unsubtyped) (Figure 8a). Thirteen cases (14.9%) were children under 6 months of age, 29 (33.3%) were 6-23 months of age, 26 (29.9%) were 2-4 years of age, 13 (14.9%) were 5-9 years of age and 6 (6.9%) were 10-16 years of age. Thirteen ICU admissions were reported in weeks 51 and 52, eight children 6-23 months of age, one 2-4 years of age, one 5-9 years of age, and three 10-16 years of age; all with influenza A.

                              To date this season, a total of 140 influenza-associated paediatric hospitalizations have been reported by the IMPACT network, the large majority of which have been influenza A (Table 4). Sixty (42.9%) of cases have been children under 2 years of age, and a total of 103 (73.6%) have been under 5 years of age. Eighteen ICU admissions have been reported: two cases with influenza B and 16 with influenza A (seven A(H1N1)pdm09, one A(H3N2), eight A(unsubtyped)). The age-distribution is as follows: eight children 6-23 months of age, three 2-4 years of age, two 5-9 years of age, and five 10-16 years of age. Among the 15 ICU cases with available data, 11 were reported to have comorbidities or concurrent infection. No deaths have been reported (Figure 9a).

                              Note: The number of hospitalizations reported through IMPACT represents a subset of all influenza-associated paediatric hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

                              Adult Influenza Hospitalizations and Deaths (PCIRN)

                              The number of new laboratory-confirmed influenza-associated adult (≥16 years of age) hospitalizations reported through active<SUP>*</SUP> surveillance by the PHAC/CIHR Influenza Research Network (PCIRN) Serious Outcomes Surveillance (SOS) network increased from 17 in week 50 to 40 in week 51, and decreased to 21 in week 52. Among the 61 cases in this 2-week period, 58 (95.1%) were influenza A, of which 7 (12.1%) were A(H1N1)pdm09, one (1.7%) was A(H3N2) and 50 (86.2%) were A(unsubtyped).

                              The age-distribution is as follows: three (4.9%) cases <20 years of age, 18 (29.5%) cases 20-44 years of age, 21 (34.4%) cases 45-64 years of age and 19 (31.1%) cases ≥65 years of age. Eleven ICU admissions were reported in weeks 51 and 52: one (9.1%) case 20-44 years of age, eight (72.7%) cases 45-64 years of age, and two (18.2%) cases ≥65 years of age (Figure 8b).

                              To date this season, 120 influenza-associated hospitalizations have been reported by the PCIRN-SOS network, 115 (95.8%) with influenza A, predominantly A(H1N1)pdm09. The majority (73%) have been adults over 45 years of age (Table 5). ICU admission was required for 17 hospitalizations: 16 cases with influenza A (6 A(H1N1)pdm09 and 10 A(unsubtyped)); 15 of the ICU admissions were >45 years of age. Of the 10 cases with information on influenza vaccination, 9 reported not having been vaccinated this season. No deaths have been reported (Figure 9b).

                              Note: PCIRN-SOS conducted passive surveillance from April 30th to November 14th, 2013. Cases reported during this period were identified by laboratory detection of influenza among patients admitted to participating hospitals. Active surveillance began November 15th during which time PCIRN site coordinators investigate cases potentially related to influenza. Data from both active and passive surveillance reported during the 2013-14 season are included in this report. The number of hospitalizations reported through PCIRN represents a subset of all influenza-associated adult hospitalizations in Canada. Delays in the reporting of data may cause data to change retrospectively.

                              Provincial/Territorial Influenza Hospitalizations and Deaths

                              In weeks 51 and 52, 186 new laboratory-confirmed influenza-associated hospitalizations were reported from participating provinces and territories.* The cases were as follows: nine children less than 6 months of age, 18 children 6-23 months, 14 children 2-4 years, nine children 5-14 years, three children 15-19 years of age, 38 adults 20-44 years, 54 adults 45-64 years and 38 adults ≥65 years of age. Age was not reported for three cases, two with A(H1N1)pdm09 and one with A(unsubtyped). The majority were cases of influenza A (181, 97.3%), of which 74 were A(H1N1)pdm09, two were A(H3N2) and 105 were A(unsubtyped). Twelve ICU admissions were reported in weeks 51 and 52, all with influenza A (five with A(H1N1)pdm09, seven with A(unsubtyped)), in one child 6-23 months of age, one 5-14 years of age, two adults 20-44 years of age, six adults 45-64 years of age, and one adult ≥65 years of age. Age information was not reported for one ICU admission. Five deaths were reported: one adult 20-44 years of age and two 45-64 years of age with influenza A(H1N1)pdm09, and two adults ≥65 years of age, with influenza A(unsubtyped) and one with influenza B. The number of new influenza-associated hospitalizations and deaths reported for the current week may include cases from Ontario that occurred in previous weeks, as a result of retrospective updates to the cumulative total.

                              To date this season, 486 influenza-associated hospitalizations have been reported, of which 475 (97.7%) had influenza A and among those 58.9% were A(H1N1)pdm09 (Table 6). Approximately half of cases (51.8%) were 20-64 years of age, and 22.6% were under 5 years of age. Fifty-nine ICU admissions have been reported this season, all cases of influenza A (44 A(H1N1)pdm09 and 15 A(unsubtyped)). The age-distribution of ICU admissions is as follows: five (8.5%) children 6-23 months, three (5.1%) 2-4 years of age, one (1.7%) 5-14 years of age, 15 (25.4%) adults 20-44 years of age, 30 (50.8%) adults 45-64 years of age, four (6.8%) adults ≥65 years of age, and one (1.7%) with missing age information.

                              Seventeen deaths have been reported: two children 6-23 months, two adults 20-44 years of age, nine 45-64 years of age, and four ≥65 years of age. Thirteen deaths were associated with influenza A(H1N1)pdm09, three with A(unsubtyped), and one with influenza B. It is important to note that the hospitalization or death does not have to be attributable to influenza, a positive laboratory test is sufficient for reporting. Detailed clinical information (e.g. underlying medical conditions) is not known for these cases.

                              * Note: Influenza-associated hospitalizations are not reported to PHAC by the following Provinces and Territory: BC, NU, QC, NS, and NB. Only hospitalizations that require intensive medical care are reported by Saskatchewan. ICU admissions are not distinguished among hospital admissions reported from Ontario. Data may also include cases reported by the IMPACT and PCIRN networks.
