    Overall Summary
    • Influenza indicators (activity levels, influenza detections, ILI and hospitalizations) in some regions across Canada continued to increase in week 41.
    • So far this year, the H3N2 has been the most common strain affecting Canadians.
    • So far this season, the majority of influenza laboratory detections and hospitalizations were in seniors ≥65 years of age.

    Influenza/ILI Activity (geographic spread)

    In week 41, the majority of regions in Canada reported no activity; however, three regions (BC(1), ON(2)) reported localized activity and 13 regions (BC(2), AB(4), MB(1), ON(2) and QC(4)) 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 continued to increase in week 41 to 50 influenza detections (1.7% of tests) (Figure 2). To date, 86% of influenza detections have been influenza A, and the majority of those subtyped have been A(H3) (Table 1). Among cases with reported age, the largest proportion was in those ≥65 years of age (56%) (Table 2).

    In week 41, detections of some respiratory viruses were at inter-seasonal levels (human metapneumovirus) or in keeping with their usual pattern of seasonal circulation (RSV, parainfluenza, and coronavirus). Detections of adenovirus were higher than in previous seasons. Detections of rhinovirus seem to have peaked in week 39 at a level higher than observed in previous seasons, but decreased over the past two weeks (Figure 3).
    For more details, see the weekly Respiratory Virus Detections in Canada Report.

    Influenza Strain Characterizations

    During the 2014-2015 influenza season, the National Microbiology Laboratory (NML) has antigenically characterized 2 influenza viruses [one A(H3N2) and one influenza B]. Both viruses were similar to the strains recommended by the WHO for the 2014-15 seasonal influenza vaccine. (Figure 4).
    Figure 4. Influenza strain characterizations, Canada, 2014-2015, N = 2

    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 2014-2015 northern hemisphere trivalent influenza vaccine include: an A/California/7/2009(H1N1)pdm09-like virus, an A/Texas/50/2012 (H3N2)-like virus, and a B/Massachusetts/2/2012-like virus (Yamagata lineage). For quadrivalent vaccines, the addition of a B/Brisbane/60/2008-like virus is recommended.

    Antiviral Resistance

    During the 2014-2015 influenza season, NML has tested 2 influenza viruses for resistance to oseltamivir and zanamivir and both were sensitive to both agents. The one influenza A virus tested for amantadine resistance was resistant (Table 3).

    Influenza-like Illness (ILI) Consultation Rate

    The national influenza-like-illness (ILI) consultation rate continued to increase, and was 31.6 per 1,000 consultations in week 41 (Figure 5). The rates since mid-June have been above the expected range for this time of year.
    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, 2014-2015

    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 41, two new laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalizations were reported by the Immunization Monitoring Program Active (IMPACT) network (Figure 8a). To date this season, seven hospitalizations have been reported by the IMPACT network, all cases of influenza A, and four of the seven were A(H3N2) (Table 4). To date, two cases were admitted to the ICU (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)
    Surveillance of laboratory-confirmed influenza-associated adult (≥16 years of age) hospitalizations by the PHAC/CIHR Influenza Research Network (PCIRN) Serious Outcomes Surveillance (SOS) network has not yet begun for the 2014-15 season (Figure 8b).
    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

    Since the start of the 2014-15 season, 25 laboratory-confirmed influenza-associated hospitalizations have been reported from participating provinces and territories*; 24 were cases of influenza A, of which the majority were A(H3N2); 56% were patients ≥65 years of age. No ICU admissions were reported. Two deaths with influenza A(H3N2) have been reported in adults ≥45 years of age. There is a reporting delay from some regions that have not yet begun surveillance and/or submission of weekly reports.
    * Note: Influenza-associated hospitalizations are not reported to PHAC by the following Provinces and Territory: BC, NU, QC, 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
    • Several influenza indicators (activity levels, influenza detections, ILI and hospitalizations) continued to increase in weeks 39 and 40. Influenza activity was reported in several regions in six provinces (BC, AB, SK, MB, ON & QC) over the two-week period.
    • Early season influenza detections show influenza A(H3N2) to be the predominant virus circulating, followed by co-circulation of influenza B.
    • In week 39, six influenza outbreaks and two ILI outbreaks were reported. No new outbreaks were reported in week 40.
    • Among laboratory detections and hospitalizations, the majority of cases were ≥65 years of age.

    Influenza/ILI Activity (geographic spread)

    In weeks 39 and 40, the number of regions in Canada reporting influenza/ILI activity increased compared to the previous two week period. In week 39, five regions (BC(2), AB(1), ON(2)) reported localized activity, and 11 regions (BC(1), AB(4), SK(1), MB(1), ON(2) and QC(2)) reported sporadic activity. In week 40, two regions in Ontario reported localized activity, and 11 regions (BC(3), AB(4), ON(2) and QC(2)) reported sporadic activity (Figure 1).
    Figure 1. Map of overall influenza/ILI activity level by province and territory, Canada, Week 40





    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 during weeks 39 and 40. The percent positive for influenza detections remains low, and reached 1.2% in week 40 (Figure 2). To date, 84% of influenza detections have been influenza A, and the majority of those subtyped have been A(H3) (Table 1). Among cases with reported age, the largest proportion was in those ≥65 years of age (55%) (Table 2).

    In weeks 39 and 40, detections of other respiratory viruses were at inter-seasonal levels (RSV, coronavirus, and human metapneumovirus). Detections of parainfluenza were in keeping with their usual pattern of seasonal circulation. Detections of adenovirus were higher than in previous seasons. Detections of rhinovirus increased in week 39 to a level higher than observed in previous seasons, but decreased in week 40 (Figure 3).

    Influenza Strain Characterizations

    The National Microbiology Laboratory (NML) has not yet reported any influenza strain characterizations for the 2014-15 season (Figure 4).
    Figure 4. Influenza strain characterizations, Canada, 2014-2015, N = 0
    <!---->
    The National Microbiology Laboratory (NML) has not yet conducted antigenic characterization of influenza viruses collected during the 2014-15 season.

    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 2014-2015 northern hemisphere trivalent influenza vaccine include: an A/California/7/2009(H1N1)pdm09-like virus, an A/Texas/50/2012 (H3N2)-like virus, and a B/Massachusetts/2/2012-like virus (Yamagata lineage). For quadrivalent vaccines, the addition of a B/Brisbane/60/2008-like virus is recommended.

    Influenza-like Illness (ILI) Consultation Rate

    The national influenza-like-illness (ILI) consultation rate continued to increase, and was 23.1 and 29.6 per 1,000 consultations in weeks 39 and 40, respectively (Figure 5). The rates since mid-June have been above the expected range for this time of year.
    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, 2014-2015

    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

    In week 39, five influenza outbreaks were reported in long-term care facilities. One was due to influenza B, and among the four due to influenza A, one was A(H3N2) and the others were A(unsubtyped) (Figure 6). Two outbreaks of influenza-like illness in schools, and one outbreak of A(H3N2) in another facility were also reported in the same week. No new outbreaks were reported in week 40.
    Figure 6. Overall number of new influenza outbreaks by report week, Canada, 2014-2015

    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 weeks 39 and 40, two new laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalizations were reported by the Immunization Monitoring Program Active (IMPACT) network (Figure 8a). To date this season, five hospitalizations have been reported by the IMPACT network, all cases of influenza A (three A(H3N2) and two A(unsubtyped)). Two cases were admitted to the ICU. The age distribution of cases ranged from 2 to 16 years.
    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)
    Surveillance of laboratory-confirmed influenza-associated adult (≥16 years of age) hospitalizations by the PHAC/CIHR Influenza Research Network (PCIRN) Serious Outcomes Surveillance (SOS) network has not yet begun for the 2014-15 season (Figure 8b).
    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.

    Overall Summary
    • Several influenza indicators (activity levels, influenza detections, ILI and hospitalizations) increased in weeks 37 and 38 compared to recent weeks.
    • Influenza A(H3N2) was the predominant circulating virus with some co-circulation of influenza B.
    • In week 38, one influenza outbreak and three ILI outbreaks were reported.
    • During these two weeks, both paediatric and adult hospitalizations with influenza were reported.

    Influenza/ILI Activity (geographic spread)

    In weeks 37 and 38, the number of regions in Canada reporting influenza/ILI activity increased. In week 37, six regions (BC(2), ON(1) and QC(3)) reported sporadic activity. In week 38, one region in Alberta reported localized activity, and 11 regions (BC(3), AB(1), SK (1), ON(4) and QC(2)) reported sporadic activity (Figure 1). In week 37, ten regions did not report data, and in week 38, one region did not report.
    Figure 1. Map of overall influenza/ILI activity level by province and territory, Canada, Week 38





    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

    Although the number of positive influenza tests increased over the two week period, the percent positive for influenza detections remains low (<1%) (Figure 2). To date, 75% of influenza detections have been influenza A, and the majority of those subtyped have been A(H3) (Table 1). Among cases with reported age, the largest proportion was in those ≥65 years of age (42%) (Table 2).

    In weeks 37 and 38, detections of other respiratory viruses were at inter-seasonal levels (RSV, coronavirus, and human metapneumovirus). Detections of parainfluenza and adenovirus were in keeping with their usual pattern of seasonal circulation. Detections of rhinovirus have increased 1-2 weeks earlier than seen in recent seasons, but are still in keeping with the usual pattern of seasonal circulation (Figure 3).
    For more details, see the weekly Respiratory Virus Detections in Canada Report.

    Influenza Strain Characterizations

    The National Microbiology Laboratory (NML) has not yet reported any influenza strain characterizations for the 2014-15 season (Figure 4).
    Figure 4. Influenza strain characterizations, Canada, 2014-2015, N = 0
    <!---->
    The National Microbiology Laboratory (NML) has not yet conducted antigenic characterization of influenza viruses collected during the 2014-15 season.

    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 2014-2015 northern hemisphere trivalent influenza vaccine include: an A/California/7/2009(H1N1)pdm09-like virus, an A/Texas/50/2012 (H3N2)-like virus, and a B/Massachusetts/2/2012-like virus (Yamagata lineage). For quadrivalent vaccines, the addition of a B/Brisbane/60/2008-like virus is recommended.

    Influenza-like Illness (ILI) Consultation Rate

    The national influenza-like-illness (ILI) consultation rate has been increasing steadily during the first four weeks of the 2014-15 season; and was 17.7 and 20.1 per 1,000 in weeks 37 and 38, respectively (Figure 5). The rates since mid-June have been above the expected range for this time of year.
    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, 2014-2015

    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 outbreak of influenza was reported in a long-term care facility in week 38 (Figure 6). Three outbreaks of influenza-like illness in schools were also reported in the same week.
    Figure 6. Overall number of new influenza outbreaks by report week, Canada, 2014-2015

    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 weeks 37 and 38, four laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalizations were reported by the Immunization Monitoring Program Active (IMPACT) network (Figure 8a). These are the first hospitalizations reported through IMPACT this season. Three of the four were cases of influenza A and two were admitted to the ICU. The age distribution of cases ranged from <6 months to 16 years.
    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)
    Surveillance of laboratory-confirmed influenza-associated adult (≥16 years of age) hospitalizations by the PHAC/CIHR Influenza Research Network (PCIRN) Serious Outcomes Surveillance (SOS) network has not yet begun for the 2014-15 season (Figure 8b).
    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.

    As of September 26, 2014, confirmed cases of EV-D68 have been reported in Western and Central Canada. The EV-D68 strains detected in Canada match those associated with clusters of cases reported in the United States in recent months. Fall is the peak season for enterovirus circulation in both Canada and the US.

    Influenza/ILI Activity (geographic spread)

    In weeks 35 and 36, most regions in Canada reported no influenza/ILI activity. During these two weeks, one region in Quebec reported sporadic activity; and in week 36, two other regions (BC(1) and ON(1)) reported sporadic activity (Figure 1). In week 35, six regions did not report data, and in week 36, one region did not report.
    Figure 1. Map of overall influenza/ILI activity level by province and territory, Canada, Week 36





    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 at inter-seasonal levels in week 35 (5 detections) and week 36 (4 detections), with <1% of tests positive since early July (Figure 2). Most jurisdictions have reported only sporadic numbers of influenza detections in recent weeks (Table 1, Table 2).

    In weeks 35 and 36, detections of most other respiratory viruses were at inter-seasonal levels (RSV, coronavirus, and human metapneumovirus). Detections of parainfluenza, adenovirus and rhinovirus were in keeping with their usual pattern of seasonal circulation (Figure 3).

    Influenza Strain Characterizations

    The National Microbiology Laboratory (NML) has not yet reported any influenza strain characterizations for the 2014-15 season (Figure 4).
    Figure 4. Influenza strain characterizations, Canada, 2014-2015, N = 0
    <!---->
    The National Microbiology Laboratory (NML) has not yet conducted antigenic characterization of influenza viruses collected during the 2014-15 season.

    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 2014-2015 northern hemisphere trivalent influenza vaccine include: an A/California/7/2009(H1N1)pdm09-like virus, an A/Texas/50/2012 (H3N2)-like virus, and a B/Massachusetts/2/2012-like virus (Yamagata lineage). For quadrivalent vaccines, the addition of a B/Brisbane/60/2008-like virus is recommended.

    Influenza-like Illness (ILI) Consultation Rate

    The national influenza-like-illness (ILI) consultation rate increased from 8.0 consultations per 1,000 patient visits in week 34 to 13.6 per 1,000 in week 35 and decreased slightly to 12.3 per 1,000 in week 36 (Figure 5). The rates since mid-June have been above the expected range for this time of year.
    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, 2014-2015

    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)
    No laboratory-confirmed influenza-associated paediatric (≤16 years of age) hospitalizations have been reported by the Immunization Monitoring Program Active (IMPACT) network for the 2014-15 season (Figure 8a).
    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)
    Surveillance of laboratory-confirmed influenza-associated adult (≥16 years of age) hospitalizations by the PHAC/CIHR Influenza Research Network (PCIRN) Serious Outcomes Surveillance (SOS) network has not yet begun for the 2014-15 season (Figure 8b).
    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.
