    Overall Influenza Summary - Week 6 (February 7 to February 13, 2010)

    During week 6, all influenza indicators continued to decline compared to the previous week and were still considerably under the expected level for this time of the year. Only 0.24% of the specimens tested were positive for influenza A. Three out of four (75%) of the positive influenza A subtyped specimens were pandemic H1N1 2009 this week.
    In week 6, nineteen regions in BC, AB, MB, ON, QC, NS & NU reported sporadic activity, while thirty-five regions reported no activity in BC, AB, SK, MB, ON, QC, NB, PE, NS, NL, YT & NT. The 5 influenza outbreaks reported this week were all in schools (NS).

    Overall Number of Influenza Outbreaks, Canada, by Report Week, 2009-2010



    Note that this was the first year that all the provinces and territories were reporting on influenza outbreaks in schools (greater than 10% absenteeism on any day most likely due to ILI) which has increased considerably the total number of outbreaks reported compared to previous years.

    ILI consultation rate
    During week 6, the national ILI consultation rate was 11 consultations per 1,000 patient visits (see ILI graph) which was similar to the previous weeks and still significantly below the expected range for this time of the year. All provinces and territories had similar ILI consultation rates compared to their respective ILI rates in the previous week. Those under 20 years of age still had the highest consultation rates, with 64 and 13 per 1,000 patient visits among children under 5 years of age and among those 5 to 19 years of age, respectively.

    Note: No data available for mean rate in previous years for weeks 19 to 39 (1996-1997 through 2002-2003 seasons).
    Delays in the reporting of data may cause data to change retrospectively.
    Paediatric and Adult Influenza Hospitalizations and Deaths
    In week 6, no laboratory-confirmed influenza-associated paediatric (under 17 years of age) hospitalizations were reported through the Immunization Monitoring Program Active (IMPACT) network. 1325* hospitalizations have been reported since week 17 (April 26): 97.0% of these hospitalizations were due to pandemic H1N1 2009. Since the beginning of the pandemic, eleven paediatric deaths due to pandemic H1N1 2009 were reported through the IMPACT network among children 16 years of age or under.
    *Delays in the reporting of data may cause data to change restrospectively.
    During week 6, no report was received from the Canadian Nosocomial Infection Surveillance Program (CNISP) on influenza-associated adult (16 years of age or older) hospitalizations and deaths. Since week 47 (November 22, 2009), 55 hospitalizations and 8 deaths have been reported through CNISP among adults 16 years of age or older. All of these hospitalizations and deaths were due to pandemic H1N1 2009. From June 1, 2009 to February 19, 2010, of the 552 laboratory-confirmed influenza cases among hospitalized adults reported through 27 of CNISP sentinel sites, 70% were pandemic H1N1 2009 cases. For these pandemic H1N1 2009 cases, most were among women (51%), 1.4% presented with influenza-associated bacteremia, 27% were admitted to the ICU, and 5% died (90% of whom had at least one underlying medical condition).
    Please note the total number of CNISP reporting sites fluctuates weekly.
    Laboratory Surveillance Summary
    The proportion of tests that were positive for influenza A was 0.24% during week 6 which remained at a very low level (see Tests table). All provinces had a similar or lower proportion of positive tests for influenza compared to the previous week. During week 6, a total of 6 specimens tested positive for influenza (all A) and 3/4 (75%) of the positive influenza A subtyped specimens were pandemic H1N1 2009. Note that QC reported 44 positive specimens for A/H3N2 and 8 specimens for influenza B and ON reported 6 specimens for influenza B since August 30, 2009. The proportion of specimens positive for respiratory syncytial virus increased to 27.0% during week 6. Positive specimens were reported from all provinces except NB (data not shown). Also, the proportion of positive parainfluenza and adenovirus tests were higher than the proportion of positive tests for influenza.

    Sale of antivirals (AV) in Canada

    Nationally, antiviral prescriptions appear to be at the levels seen prior to the second wave. During week 6, antiviral prescription monitoring demonstrated a levelling-off in antiviral prescriptions in most provinces and territories. An analysis of antiviral data at the Health Region level demonstrated low antiviral prescription rates among the vast majority of Health Regions for the week of February 7 to February 13, 2010. None of the Health Regions reported an antiviral rate greater than 2.5 antivirals/1000 other prescriptions.

    Canadian situation

    Antigenic Characterization
    Since September 1, 2009, the National Microbiology Laboratory (NML) has antigenically characterized 790 pandemic H1N1 2009 viruses and 10 seasonal influenza viruses (2 influenza A/H1N1, 7 H3N2, and 1 B virus) that were received from Canadian laboratories. Of the 790 pandemic H1N1 2009 viruses characterized, 786 (99.5%) were antigenically related to A/California/7/2009, which is the pandemic reference virus selected by WHO for the pandemic H1N1 2009 vaccine. Four viruses (0.5%) tested showed reduced titer with antisera produced against A/California/7/09. Of the seven seasonal influenza A (H3N2) viruses characterized, one was related to A/Brisbane/10/07, which is the influenza A/H3N2 component recommended for the 2009-10 influenza vaccine and six viruses were antigenically related to A/Perth/16/09, which is the WHO recommended influenza A (H3N2) component for the 2010 Southern Hemisphere vaccine.
    Antiviral Resistance
    NML: Pandemic H1N1 2009 viruses tested so far have been sensitive to zanamivir (981 samples) but resistant to amantadine (1051 samples).
    NML/Provinces: Thirteen cases of oseltamivir resistant pandemic H1N1 2009 were reported to date in Canada: one in British Columbia, four in Alberta, one in Manitoba, four in Ontario, two in Quebec, and one in New Brunswick. The 13 resistant cases were associated with oseltamivir treatment/prophylaxis.
    International update

    Global information
    WHO: Worldwide more than 212 countries and overseas territories or communities reported laboratory confirmed cases of pandemic H1N1 2009, including at least 15,292 deaths as of February 7, 2010. In the temperate zone of the Northern hemisphere, overall pandemic influenza activity continued to decline in most countries. The most active areas of transmission continue to be in later peaking areas, particularly Northern Africa, South Asia, and East Asia. In Europe, although pandemic influenza virus continues to circulate widely, particularly across central, southern, and eastern Europe, the overall intensity of pandemic influenza activity has declined substantially from peaks of activity seen earlier during the winter transmission period. In temperate regions of the southern hemisphere, sporadic cases of pandemic H1N1 2009 continued to be reported without evidence of sustained community transmission. Pandemic H1N1 2009 virus continued to be the predominant virus circulating worldwide. In addition to the increasing proportion of seasonal influenza type B viruses recently detected in China, low levels of seasonal H3N2 and type B viruses are circulating in parts of Africa, East and Southeast Asia and are being detected only sporadically in other continents.

    <http://www.who.int/csr/disease/swineflu/laboratory12_02_2010/en/index.html>
    Antiviral resistance: To date, 245 pandemic H1N1 2009 isolates worldwide have been found to be resistant to oseltamivir, all with the same H275Y mutation and all remain sensitive to zanamivir.

    Geographic update
    United States: During week 5 (January 31-February 6, 2010), influenza activity remained at approximately the same levels as last week in the United States. 4.8% of the specimens tested this week were positive for influenza. While no states reported widespread influenza activity, 6 states reported regional influenza activity, Puerto Rico and 11 states reported local activity and the majority of the states reported sporadic influenza activity. The proportion of outpatient visits for influenza-like illness (ILI) was 2.1% which was below the national baseline of 2.3%. Three of 10 regions reported ILI above region-specific baseline levels. The proportion of deaths attributed to pneumonia and influenza decreased slightly over the previous week and remained below the epidemic threshold for this time of the year. Three influenza-associated pediatric deaths were reported during week 5: two deaths were associated with pandemic H1N1 2009 virus infection and one was associated with influenza A virus for which the subtype was undetermined. Of the subtyped influenza A viruses reported to CDC, 100% were pandemic H1N1 2009 viruses.
    <http://www.cdc.gov/flu/weekly/>
    Europe: In Europe for week 5/2010 (February 1-7, 2010), the pandemic H1N1 2009 was well past its peak. In eight countries (Austria, Bulgaria, Czech Republic, Germany, Greece, Italy, Malta, Slovakia), local or regional transmission of the pandemic virus continues at low to medium intensity. Elsewhere intensity was low, but sporadic transmission of the pandemic virus was reported in the majority of countries. For the majority of countries that reported age-specific incidence of ILI, the most affected age group was 0?14. The number of reported SARI (severe acute respiratory illness) cases continued to decline. Of the 62 SARI cases reported this week, 30 (48%) were known to have required ICU admission and 16 (24%) needed ventilator support. Of the 39 SARI cases for whom underlying conditions were reported, 9 (23%) had no known underlying condition. Asthma and other chronic lung diseases alone or associated with other conditions were reported in 12 (31%) cases. Of the 910 specimens collected by sentinel physicians, 76 (8.4%) were positive for influenza virus, mainly the pandemic virus; this is consistent with a declining trend. Since their peak in week 01/2010, the total number of respiratory syncytial virus (RSV) detections in 11 countries has been decreasing. However in Austria, Denmark, Estonia, Germany, Latvia and Sweden, the number of RSV positive samples has increased for at least two consecutive weeks. In contrast to the pandemic virus there is currently no evidence of virus circulation due to other influenza A viruses this week, but there is some circulation of influenza B viruses.
    <http://ecdc.europa.eu/en/publications/Publications/100212_EISN_Weekly_Influenza_Surveillance_Overview .pdf>
    Asia: In South and Southeast Asia, pandemic influenza virus continues to circulate widely across the region, however, overall activity continues to decrease or remain low in most places. In India, influenza activity continued to decline in all regions of the country, however, the most active areas of transmission are currently in the western states. In Thailand, overall activity remains low, although focal areas of increased ILI activity were reported in central and northern Thailand. In East Asia, pandemic influenza transmission remains geographically widespread across the region, however, overall activity continued to decline. In China, pandemic and seasonal influenza viruses continue to co-circulate, however, over the last several weeks, seasonal influenza type B viruses have been predominant. In Japan, influenza activity continues to decrease towards seasonal baselines, including in Okinawa which is experiencing greater levels of influenza activity than other parts of the country. In Republic of Korea (S. Korea), levels of ILI have decreased substantially to near baseline levels. In addition to the increasing proportion of seasonal influenza type B viruses recently detected in China, low levels of seasonal H3N2 and type B viruses are circulating in parts of East and Southeast Asia.

      Overall Influenza Summary - Week 7 (February 14 to February 20, 2010)

      During week 7, overall influenza activity remained at approximately the same level as last week and all influenza indicators were still considerably below expected levels for this time of the year. While only 0.24% (6/2505) of the specimens tested were positive for influenza A this week, respiratory syncytial virus increased to 28.0% of positive respiratory specimens tested during week 7.
      In week 6, twenty regions in AB, MB, ON, QC, NS & NU reported sporadic activity, while thirty-three regions reported no activity in BC, AB, SK, MB, ON, QC, NB, PE, NS, NL, YT & NT. One region in BC did not report activity this week. The 4 influenza outbreaks reported this week were all in schools (all in NS).

      Overall Number of Influenza Outbreaks, Canada, by Report Week, 2009-2010



      Note that this was the first year that all the provinces and territories were reporting on influenza outbreaks in schools (greater than 10% absenteeism on any day most likely due to ILI) which has increased considerably the total number of outbreaks reported compared to previous years.

      ILI consultation rate
      During week 7, the national ILI consultation rate was 15 consultations per 1,000 patient visits (see ILI graph) which was similar to previous weeks and is still below the expected range for this time of year. All provinces and territories had similar or lower ILI consultation rates compared to their respective ILI rates in the previous weeks except PE, NS and NL which had a slightly higher rate this week. Those under 20 years of age still had the highest consultation rates: 40 per 1,000 among children under 5 years of age and 27 per 1,000 among those 5 to 19 years of age.

      Delays in the reporting of data may cause data to change retrospectively.
      Paediatric and Adult Influenza Hospitalizations and Deaths
      In week 7, one laboratory-confirmed influenza-associated paediatric (under 17 years of age) hospitalization was reported through the Immunization Monitoring Program Active (IMPACT) network. The case was reported as pandemic H1N1 2009. 1327* hospitalizations have been reported since week 17 (April 26): 96.9% of these hospitalizations were due to pandemic H1N1 2009. Since the beginning of the pandemic, ten paediatric deaths due to pandemic H1N1 2009 were reported through the IMPACT network among children 16 years of age or under. The total number of paediatric deaths has changed from 11 to 10 since an investigation confirmed that the case was not pandemic H1N1 2009 positive. 70% of those deaths reported at least one underlying medical condition.
      *Delays in the reporting of data may cause data to change restrospectively.
      During weeks 6 and 7, no new laboratory-confirmed influenza-associated adult (16 years of age and older) hospitalizations were reported through the Canadian Nosocomial Infection Surveillance Program (CNISP) from 15 of 50 reporting sites. Since week 47 (November 22, 2009), 55 hospitalizations and 8 deaths have been reported through CNISP among adults 16 years of age or older. All of these hospitalizations and deaths were due to pandemic H1N1 2009. From June 1, 2009 to February 19, 2010, of the 552 laboratory-confirmed influenza cases among hospitalized adults reported through 27 of CNISP sentinel sites, 70% were pandemic H1N1 2009 cases, 28% were unsubtyped influenza A and the remaining 2% were either influenza A/H1N1, influenza A/H3N2 or influenza B. For these pandemic H1N1 2009 cases, 1.4% presented with influenza-associated bacteremia, 27% were admitted to the ICU, and 5% died (90% of whom had at least one underlying medical condition).
      Please note the total number of CNISP reporting sites fluctuates weekly.
      Laboratory Surveillance Summary
      The proportion of tests that were positive for influenza A was 0.24% during week 7 which remained at a very low level (see Tests table). All provinces had a similar or lower proportion of positive tests for influenza compared to the previous week except Quebec which had a higher proportion this week. During week 7, a total of 6 specimens tested positive for influenza (all A) and 3/4 (75%) of the positive influenza A subtyped specimens were pandemic H1N1 2009. Note that QC reported 44 positive specimens for A/H3N2 and 8 specimens for influenza B and ON reported 6 specimens for influenza B since August 30, 2009. The proportion of specimens positive for respiratory syncytial virus (RSV) increased to 28.0% during week 7. Positive specimens for RSV were reported from all provinces except NB (data not shown). The proportion of positive parainfluenza and adenovirus tests remained under the 3% positivity rate.

      Sale of antivirals (AV) in Canada

      During week 7, antiviral prescription monitoring continued to demonstrate a levelling-off in antiviral prescriptions with little change compared to last week among all provinces and territories. An analysis of antiviral data at the Health Region level demonstrated low antiviral prescription rates among all Health Regions for the week of February 14 to February 20, 2010. None of the Health Regions reported an antiviral rate greater than 2.5 antivirals/1000 other prescriptions.

      Canadian situation

      Antigenic Characterization
      Since September 1, 2009, the National Microbiology Laboratory (NML) has antigenically characterized 835 pandemic H1N1 2009 viruses and 13 seasonal influenza viruses (3 influenza A/H1N1, 9 H3N2, and 1 B virus) that were received from Canadian laboratories. Of the 835 pandemic H1N1 2009 viruses characterized, 831 (99.5%) were antigenically related to A/California/7/2009, which is the pandemic reference virus selected by WHO for the pandemic H1N1 2009 vaccine. Four viruses (0.5%) tested showed reduced titer with antisera produced against A/California/7/09. Of the nine seasonal influenza A (H3N2) viruses characterized, one was related to A/Brisbane/10/07, which was the influenza A/H3N2 component recommended for the 2009-10 influenza vaccine and eight viruses were antigenically related to A/Perth/16/09, which is the WHO recommended influenza A (H3N2) component for the 2010 -2011 Northern Hemishpere vaccine. Three seasonal influenza A/H1N1 viruses characterized were related to A/Brisbane/59/07, which was the influenza A/H1N1 component recommended for the 2009-10 influenza vaccine.
      Antiviral Resistance
      NML: Thirteen cases of oseltamivir resistant pandemic H1N1 2009 were reported to date in Canada: one in British Columbia, four in Alberta, one in Manitoba, four in Ontario, two in Quebec, and one in New Brunswick. The 13 resistant cases were associated with oseltamivir treatment/prophylaxis.
      NML/Provinces: All pandemic H1N1 2009 viruses tested so far have been sensitive to zanamivir (1031 samples) but resistant to amantadine (1115 samples).
      International update

      Global information
      WHO: As of February 14, 2010, over 212 countries and overseas territories or communities worldwide reported cases of pandemic H1N1 2009 (at least 15,921 deaths). During weeks 1-4, pandemic H1N1 2009 viruses persisted in some countries around the world although the majority of Northern Hemisphere countries reported decreasing activity. Activity in the Southern Hemisphere was variable but mainly sporadic. The pandemic virus continued to be the predominant circulating influenza virus in all countries where influenza was reported with the exception of China where influenza B was the predominant virus.
      <http://www.who.int/csr/don/2010_02_19/en/index.html> and
      <http://www.who.int/csr/disease/influenza/update/en/index.html>
      On February 23, 2010, the Director General of the WHO sought the Emergency Committee's views on the determination of the pandemic status. After reviewing the evidence (i.e. new community level transmission activity in West Africa, winter months of the Southern Hemisphere has not yet started), and holding extensive discussion, it was determined that there had been no change in the pandemic phase. The situation will be monitored closely and the Committee will convene again to discuss the global pandemic status in the next several weeks.
      <http://www.who.int/csr/disease/swineflu/7th_meeting_ihr/en/index.html>
      Antiviral resistance: To date, 248 pandemic H1N1 2009 isolates worldwide have been found to be resistant to oseltamivir, all with the same H275Y mutation and all remain sensitive to zanamivir.
      <http://www.who.int/csr/disease/swineflu/update_oseltamivir_resistant20100210.pdf>
      2010-2011 influenza season vaccine: The WHO recommends that the following viruses be used for influenza vaccines in the 2010-2011 influenza season (northern hemisphere): an A/California/7/2009 (H1N1)-like virus; an A/Perth/16/2009 (H3N2)-like virus; and a B/Brisbane/60/2008-like virus.
      <http://www.who.int/csr/disease/influenza/recommendations2010_11north/en/index.html>
      Geographic update
      United States: During week 6, influenza activity remained at approximately the same levels as last week in the United States with the majority of states reporting sporadic influenza activity (6 states reported regional and 11 states and Puerto Rico reporting localized). Of the 3,656 specimens tested for influenza in week 6, 129 (3.5%) were positive for influenza (125 were influenza A and 4 were influenza B). All of the influenza A viruses subtyped were pandemic H1N1 2009 viruses. The proportion of deaths attributed to pneumonia and influenza increased slightly but remained below the epidemic threshold. The proportion of outpatient visits for ILI (2.1%) remained below baseline levels. Two influenza-associated pediatric deaths were reported this week and both were associated with pandemic H1N1 2009 virus infection.
      <http://www.cdc.gov/flu/weekly/>
      Europe: The 2009 influenza A(H1N1) pandemic is well past its winter peak in Europe, with the majority of the countries reporting only sporadic transmission of the pandemic virus. In seven countries (the majority of which are in Eastern Europe), local or regional transmission of the pandemic virus continued at low to medium intensity. In addition to the pandemic H1N1 2009 virus, there was currently no evidence of wide circulation of other influenza A viruses. A few influenza B viruses have been detected. Respiratory syncytial virus detections continued to decline since peaking in week 1. Additionally, the number of severe acute respiratory infection cases by week of onset (29 reported in week 6) has been declining since the peak in week 46.
      <http://ecdc.europa.eu/en/publications/Publications/100219_EISN_Weekly_Influenza_Surveillance_Overview .pdf>
      Asia: In Southeast Asia, several countries (Thailand, Myanmar and Indonesia) reported an increasing trend of respiratory diseases activity but overall intensity remained low. In South Asia, influenza activity persisted in the northern and western states of India, however, overall influenza activity continued to decline or remained low in other countries. In East and West Asia, transmission of pandemic influenza virus persisted but was either steadily declining or the overall intensity of current activity remained low, with the exception of North Korea where an increasing trend of respiratory diseases activity was reported.
      <http://www.who.int/csr/don/2010_02_19/en/index.html>
      Africa: Several countries in West Africa reported increases in the number of cases but there is as yet insufficient evidence to conclude that widespread community transmission is occurring. In North Africa, pandemic influenza transmission persists but activity has declined substantially over the past month. In Sub-Saharan Africa, sporadic pandemic influenza virus transmission was reported.
      <http://www.who.int/csr/don/2010_02_19/en/index.html>
      Southern Hemisphere
      Australia: As at 12 February 2010, there have been 37,713 confirmed cases of pandemic (H1N1) 2009 and 191 deaths reported in Australia. National influenza activity remains low and is at levels experienced at the same time in previous years. <http://www.healthemergency.gov.au/internet/healthemergency/publishing.nsf/Content/ozflucurrent.htm>
      New Zealand: As of February 21, 2010, there have been 3,300 cases of pandemic H1N1 2009 reported in New Zealand with 20 deaths.

        Overall Influenza Summary - Week 8 (February 21 to February 27, 2010)

        During week 8, overall influenza activity remained at approximately the same level as last week and all influenza indicators were still considerably below expected levels for this time of the year. Of the 2,646 specimens tested for influenza in week 8, 7 (0.26%) were positive of which 6 (86%) were for influenza A and one (14%) was positive for influenza B. Of the 5 influenza A viruses that were subtyped, all were pandemic H1N1 2009. Respiratory syncytial virus detections were still high but the proportion of positive detections declined for the first time since the beginning of 2010 to 24.0% in week 8.
        In week 8, 14 regions in AB, ON, QC & NS reported sporadic activity, while 39 regions reported no activity. One region in BC is not reporting until further notice. No influenza outbreaks were reported this week.

        Overall Number of Influenza Outbreaks, Canada, by Report Week, 2009-2010



        Note that this was the first year that all the provinces and territories were reporting on influenza outbreaks in schools (greater than 10% absenteeism on any day most likely due to ILI) which has increased considerably the total number of outbreaks reported compared to previous years.

        ILI consultation rate
        During week 8, the national ILI consultation rate was 10 consultations per 1,000 patient visits (see ILI graph) which was still considerably below the expected range for this time of year (range from 25 to 44 consultations per 1,000 patient visits). All provinces and territories had similar or lower ILI consultation rates compared to their respective ILI rates in the previous weeks except NB which had a slightly higher rate this week. Those under 20 years of age still had the highest consultation rates with 18 ILI consultations per 1,000 patients visits.

        Note: No data available for mean rate in previous years for weeks 19 to 39 (1996-1997 through 2002-2003 seasons).
        Delays in the reporting of data may cause data to change retrospectively.
        Paediatric and Adult Influenza Hospitalizations and Deaths
        In week 8, one laboratory-confirmed influenza-associated paediatric (under 17 years of age) hospitalization was reported through the Immunization Monitoring Program Active (IMPACT) network. The hospitalization was due to influenza A (unsubtyped). A total of 1328* hospitalizations have been reported since week 17 (April 26, 2009), of which 96.8% were due to pandemic H1N1 2009. Since the beginning of the pandemic, ten paediatric deaths due to pandemic H1N1 2009 were reported through the IMPACT network among children 16 years of age or under. Seven (70%) of those deaths reported had at least one underlying medical condition.
        *Delays in the reporting of data may cause data to change restrospectively.
        During week 8, no new laboratory-confirmed influenza-associated adult (16 years of age and older) hospitalizations were reported through the Canadian Nosocomial Infection Surveillance Program (CNISP) from 14 of 50 reporting sites. Since week 47 (November 22, 2009), 55 hospitalizations and 8 deaths have been reported through CNISP among adults 16 years of age or older. All of these hospitalizations and deaths were due to pandemic H1N1 2009. From June 1, 2009 to February 19, 2010, of the 552 laboratory-confirmed influenza cases among hospitalized adults reported through 27 of CNISP sentinel sites, 385 (70%) were pandemic H1N1 2009 cases, 152 (28%) were unsubtyped influenza A and the remaining 11 (2%) were either influenza A/H1N1, influenza A/H3N2 or influenza B. For these pandemic H1N1 2009 cases, 1.3% (5/365) presented with influenza-associated bacteremia, 27% (100/376) were admitted to the ICU, and 5% (20/385) died (90% of whom had at least one underlying medical condition).
        Please note the total number of CNISP reporting sites fluctuates weekly and most of the reporting sites started in late fall 2009.
        Laboratory Surveillance Summary
        The proportion of tests that were positive for influenza during week 8 (0.26%, 7/2,646) remained at a very low level for this time of year (see Tests table). Of the positive tests, 6 (86%) were for influenza A and one (14%) was positive for influenza B. Of the 5 influenza A viruses that were subtyped, all were pandemic H1N1 2009. All provinces had a similar or lower proportion of positive tests for influenza compared to the previous weeks. Note that since August 30, 2009, influenza A/H3N2 detections were highest in QC (84.6% or 44/52) and influenza B detections were highest in QC (60% or 9/15) and ON (40% or 6/15). Respiratory syncytial virus detections were still high but the proportion of positive detections declined for the first time since the beginning of 2010 to 24.0% in week 8. Positive specimens for RSV were reported from all provinces except NB and NL (data not shown). The proportion of positive parainfluenza and adenovirus tests remained under the 3% positivity rate.

        Sale of antivirals (AV) in Canada

        During week 8, antiviral prescription monitoring continued to demonstrate a levelling-off in antiviral prescriptions with little change compared to last week among all provinces and territories. An analysis of antiviral data at the Health Region level demonstrated low antiviral prescription rates among all Health Regions for the week of February 21 to February 27, 2010. Only one Health Region in AB reported an antiviral rate greater than 2.5 antivirals/1000 other prescriptions.

        Canadian situation

        Antigenic Characterization
        Since September 1, 2009, the National Microbiology Laboratory (NML) has antigenically characterized 835 pandemic H1N1 2009 viruses and 16 seasonal influenza viruses (3 influenza A/H1N1, 10 H3N2, and 3 B virus) that were received from Canadian laboratories. Of the 835 pandemic H1N1 2009 viruses characterized, 831 (99.5%) were antigenically related to A/California/7/2009, which is the pandemic reference virus selected by WHO for the pandemic H1N1 2009 vaccine. Four viruses (0.5%) tested showed reduced titer with antisera produced against A/California/7/09. Of the ten seasonal influenza A (H3N2) viruses characterized, two were related to A/Brisbane/10/07, which was the influenza A/H3N2 component recommended for the 2009-10 influenza vaccine and eight viruses were antigenically related to A/Perth/16/09, which is the WHO recommended influenza A (H3N2) component for the 2010 -2011 Northern Hemishpere vaccine. Three seasonal influenza A/H1N1 viruses characterized were related to A/Brisbane/59/07, which was the influenza A/H1N1 component recommended for the 2009-10 influenza vaccine.Of the three influenza B virus characterized, two were antigenically related to B/Brisbane/60/08, which was the recommended influenza B component for the 2009-10 influenza vaccine. One B virus was related to the previous vaccine virus B/Florida/4/2006 (Yamagata lineage).
        Antiviral Resistance
        NML/Provinces: Thirteen cases of oseltamivir resistant pandemic H1N1 2009 were reported to date in Canada: one in British Columbia, four in Alberta, one in Manitoba, four in Ontario, two in Quebec, and one in New Brunswick. The 13 resistant cases were associated with oseltamivir treatment/prophylaxis
        NML: All pandemic H1N1 2009 viruses tested so far have been sensitive to zanamivir (1042 samples) but resistant to amantadine (1121 samples).
        International update

        Global information
        WHO: As of February 26, 2010, over 213 countries and overseas territories or communities worldwide reported cases of pandemic H1N1 2009 (at least 16,226 deaths). In the temperate zone of the northern hemisphere, pandemic influenza virus continued to be detected across many countries, however, overall influenza activity continued to wane in most places. The most active areas of transmission were currently in parts of South and Southeast Asia and in limited areas of Eastern and Southeastern Europe. Pandemic influenza (H1N1) 2009 virus continued to be the predominant influenza virus circulating worldwide. In addition to the increasing proportion of seasonal influenza type B viruses recently detected in China, low levels of seasonal H3N2 and type B viruses were circulating in parts of Africa and Asia. Respiratory disease activity was increasing in many areas of the world due to increasing transmission of influenza type B and respiratory syncytial virus. Seasonal influenza H3N2 continued to be detected in areas of Asia and east Africa.
        <http://www.who.int/csr/don/2010_02_26/en/index.html>
        Antiviral resistance: To date, 253 pandemic H1N1 2009 isolates worldwide have been found to be resistant to oseltamivir, all with the same H275Y mutation and all remained sensitive to zanamivir.
        < http://www.who.int/csr/disease/swineflu/Oseltamivirresistant2010_02_26.pdf>
        2010-2011 influenza season vaccine: The WHO recommends that the following viruses be used for influenza vaccines in the 2010-2011 influenza season (northern hemisphere): an A/California/7/2009 (H1N1)-like virus; an A/Perth/16/2009 (H3N2)-like virus; and a B/Brisbane/60/2008-like virus.
        <http://www.who.int/csr/disease/influenza/recommendations2010_11north/en/index.html>
        Geographic update
        United States: During week 7, influenza activity remained at approximately the same levels as last week in the United States with the majority of states reporting sporadic influenza activity (3 states reported regional and 8 states and Puerto Rico reporting localized). Of the 4,209 specimens tested for influenza in week 7, 185 (4.4%) were positive for influenza (181 were influenza A and 4 were influenza B). All of the influenza A viruses subtyped were pandemic H1N1 2009 viruses. The proportion of deaths attributed to pneumonia and influenza (7.4%) and the proportion of outpatient visits for ILI (1.8%) declined from the previous week and both remain below baseline levels. Three influenza-associated pediatric deaths were reported this week: one was associated with pandemic H1N1 2009 virus infection and the other two were associated with influenza A (subtype undetermined).
        <http://www.cdc.gov/flu/weekly/index.htm>
        Europe: The 2009 influenza A(H1N1) pandemic is well past its winter peak in Europe, with the majority of the countries reporting only sporadic activity or no geographic spread of the pandemic virus. Although circulation of 2009 pandemic A(H1N1) influenza virus has diminished, there was still no evidence of wide circulation of other influenza A viruses apart from few influenza A(H3N2) and B viruses.
        < http://ecdc.europa.eu/en/activities/surveillance/EISN/Newsletter/100226_EISN_Weekly_Influenza_Surveillance_Overview .pdf>
        Asia: In Southeast Asia, pandemic influenza virus continued to circulate in some areas, however, the overall intensity of respiratory diseases activity remained low and unchanged, except in a few countries (Brunei Darussalam, Myanmar and Thailand). Pandemic influenza and seasonal influenza type B viruses continued to co-circulate in East Asia. In China, the proportion of positive seasonal influenza type B viruses increased during the last week. Overall influenza activity continued to decline in Japan, South Korea, Hong Kong SAR (China) and in Chinese Taipei. In South Asia, overall influenza activity remained low, however, pandemic influenza virus transmission persisted in the western part of India. In West Asia, an increasing trend of respiratory diseases was reported in Afghanistan, however, it is unknown if the recent increase is associated with circulation of influenza virus.
        <http://www.who.int/csr/don/2010_02_26/en/index.html>
        Africa: In North Africa, pandemic influenza virus continued to circulate at low levels as rates of illness in most countries in the region continued to decline or return to baseline. In Sub-Saharan Africa, pandemic influenza virus transmission continued to be sporadic in most areas of the continent. Several countries in West Africa continued to report slight increases in the numbers of confirmed cases of pandemic influenza indicating that community transmission is likely beginning in the area; however, data were very limited.
        <http://www.who.int/csr/don/2010_02_26/en/index.html>
        Central & South America and the Caribbean: In the the Americas, pandemic influenza virus continued to circulate at low levels but overall pandemic influenza activity continued to decline or remain low in most places. In Central America and Caribbean, pandemic influenza virus transmission persisted but overall activity remained low or unchanged in most places.
        < http://www.who.int/csr/don/2010_02_26/en/index.html>
        Australia: As of 19 February 2010, there have been 37,713 confirmed cases of pandemic (H1N1) 2009 reported in Australia. National influenza activity remained low and was at levels experienced at the same time in previous years.
        < http://www.healthemergency.gov.au/internet/healthemergency/publishing.nsf/Content/ozflucurrent.htm>
        New Zealand: As of February 28, 2010, there have been 3,300 cases of pandemic H1N1 2009 reported in New Zealand with 20 deaths. The ILI consultation rate for week 8 was 14.3 per 100,000 which was below baseline.

          Overall Influenza Summary - Week 9 (February 29 to March 6, 2010)

          During week 9, the overall influenza activity remained low for at least 11 consecutive weeks and all influenza indicators were still considerably below expected levels for this time of the year. For the first time since the beginning of the pandemic, the proportion of positive tests for influenza B (0.08%) was higher than the proportion for influenza A (0,04%).
          In week 9, only one region (BC) reported localized activity. 10 regions in ON, QC & NS reported sporadic activity, while 41 regions reported no activity. One region in AB did not report this week, and one region in BC is not reporting until further notice. One influenza outbreak was reported this week in a school (BC).

          Overall Number of Influenza Outbreaks, Canada, by Report Week, 2009-2010



          Note that this was the first year that all the provinces and territories were reporting on influenza outbreaks in schools (greater than 10% absenteeism on any day most likely due to ILI) which has increased considerably the total number of outbreaks reported compared to previous years.

          ILI consultation rate
          During week 9, the national ILI consultation rate was 17.4 consultations per 1,000 patient visits (see ILI graph) which was still considerably below the expected range for this time of year (range from 31.8 to 53.0 consultations per 1,000 patient visits). All reporting provinces and territories had similar or lower ILI consultation rates compared to their respective ILI rates in the previous weeks except NB which had a slightly higher rate again this week. Those under 20 years of age still had the highest consultation rates: 29.7 per 1,000 among children under 5 years of age and 32.3 per 1,000 among those 5 to 19 years of age.

          Laboratory Surveillance Summary
          The proportion of tests that were positive for influenza during week 9 (0.12%, 3/2,574) remained at a very low level for this time of year (see Tests table). Of the three positive specimens, one (33%) was positive for influenza A (pandemic H1N1 2009) and two (67%) were positive for influenza B. All provinces had a similar or lower proportion of positive tests for influenza compared to the previous weeks. Note that since August 30, 2009, influenza A/H3N2 detections were highest in QC (85% or 44/52) and influenza B detections were highest in QC (53% or 9/17) and ON (47% or 8/17). Respiratory syncytial virus detections were still high with a proportion of positive tests of 24.0% in week 9. Positive specimens for RSV were reported from all provinces except NB (data not shown). The proportion of positive parainfluenza and adenovirus tests remained under the 3% positivity rate.

            The proportion of tests that were positive for influenza during week 10 (0.34%, 8/2,383) increased slightly compared to the previous week, but still remained at a very low level for this time of year (see Tests table). Of the eight positive specimens, four (50%) were positive for pandemic H1N1 2009, two (25%) were unsubtyped influenza A and two (25%) were positive for influenza B. All provinces had a similar or lower proportion of positive tests for influenza compared to the previous weeks except BC which had a slightly higher rate this week. Note that since August 30, 2009, influenza A/H3N2 detections were highest in QC (85% or 44/52) and influenza B detections were highest in QC (47% or 9/19) and ON (53% or 10/19). Respiratory syncytial virus detections peaked during week 7 (28.3%), but were still high this week with a proportion of positive tests of 19.7%. Positive specimens for RSV were reported from all provinces (data not shown). The proportion of positive parainfluenza (2.1%) and adenovirus (1.8%) tests remained low during week 10.

              Overall Influenza Summary - Week 11 (March 14 to March 20, 2010)

              Overall influenza activity has remained low for at least 13 consecutive weeks and all influenza indicators were still considerably below expected levels for this time of the year. The proportion of tests that were positive for influenza during week 11 (0.39%, 9/2,321) remained at a very low level for this time of year.
              In week 11, eleven regions in BC, ON, QC & NS reported sporadic activity, while 42 regions reported no activity. One region in BC is not reporting until further notice. No influenza outbreaks were reported this week.

              Overall Number of Influenza Outbreaks, Canada, by Report Week, 2009-2010



              Note that this was the first year that all the provinces and territories were reporting on influenza outbreaks in schools (greater than 10% absenteeism on any day most likely due to ILI) which has increased considerably the total number of outbreaks reported compared to previous years.

              ILI consultation rate
              During week 11, the national ILI consultation rate was 7.7 consultations per 1,000 patient visits (see ILI graph) which was still considerably below the expected range for this time of year (range from 22.8 to 42.2 consultations per 1,000 patient visits). All reporting provinces and territories had similar or lower ILI consultation rates compared to their respective ILI rates in the previous weeks except PE which had a higher rate this week.

              2009-2010 compared to 1996/97 through to 2008/09 seasons




              Note: No data available for mean rate in previous years for weeks 19 to 39 (1996-1997 through 2002-2003 seasons).
              Delays in the reporting of data may cause data to change retrospectively.
              Laboratory Surveillance Summary
              The proportion of tests that were positive for influenza during week 11 (0.39%, 9/2,321) increased slightly compared to the previous week, but still remained at a very low level for this time of year (see Tests table). Of the nine positive specimens, seven (78%) were positive for pandemic H1N1 2009, one (11%) was unsubtyped influenza A and one (11%) was positive for influenza B. All provinces had a lower proportion of positive tests for influenza compared to the previous weeks except BC and ON which had a higher rate and were the only provinces to report positive specimens this week. Note that since August 30, 2009, influenza A/H3N2 detections were highest in QC (85% or 44/52) and influenza B detections were highest in QC (45% or 9/20) and ON (55% or 11/20). Respiratory syncytial virus detections peaked during week 7 (28.3%), but were still high this week with a proportion of positive tests of 18.4%. Positive specimens for RSV were reported from all provinces (data not shown). The proportion of positive parainfluenza (2.9%) and adenovirus (1.7%) tests remained low during week 11.

                Overall influenza activity has remained low for at least 14 consecutive weeks. All influenza indicators were still below expected levels for this time of the year. The proportion of tests that were positive for influenza during week 12 (0.32%, 7/2,177) remained at a low level for this time of year.
                In week 12, twelve regions in BC, ON, QC & NS reported sporadic activity, while 41 regions reported no activity. One region in BC is not reporting until further notice. No influenza outbreaks were reported this week.

                Note that this was the first year that all the provinces and territories were reporting on influenza outbreaks in schools (greater than 10% absenteeism on any day most likely due to ILI) which has increased considerably the total number of outbreaks reported compared to previous years.

                ILI consultation rate
                During week 12, the national ILI consultation rate was 20.8 consultations per 1,000 patient visits (see ILI graph) which was higher than the previous weeks, but remained slightly below the expected range for this time of year (range from 22.5 to 37.5 consultations per 1,000 patient visits). Those between 20 and 64 years of age had the highest consultation rates this week with 25.2 consultations per 1,000 patient visit followed by children under 5 years of age (23.9 per 1,000).

                2009-2010 compared to 1996/97 through to 2008/09 seasons




                Note: No data available for mean rate in previous years for weeks 19 to 39 (1996-1997 through 2002-2003 seasons).
                Delays in the reporting of data may cause data to change retrospectively.
                Laboratory Surveillance Summary
                The proportion of tests that were positive for influenza during week 12 (0.32%, 7/2,177) was similar to the previous week and still remained at a low level for this time of year (see Tests table). Of the seven positive specimens, three (43%) were positive for pandemic H1N1 2009, three (43%) were unsubtyped influenza A and one (14%) was positive for influenza B. Again this week, BC and ON were the only provinces to report positive specimens. Note that since August 30, 2009, influenza A/H3N2 detections were highest in QC (85% or 44/52) and influenza B detections were highest in QC (43% or 9/21) and ON (57% or 12/21). Respiratory syncytial virus detections peaked during week 7 (28.3%), but were still high this week with a proportion of positive tests of 17.7%. Positive specimens for RSV were reported from all provinces (data not shown). The proportion of positive parainfluenza (2.9%) and adenovirus (1.2%) tests remained low during week 12.

                  Overall Influenza Summary - Week 13 (March 28 to April 3, 2010)

                  Overall influenza activity has remained low for at least 15 consecutive weeks. All influenza indicators were still below expected levels for this time of the year. The proportion of tests that were positive for influenza during week 13 (0.32%, 6/1,858) remained at a low level for this time of year.
                  In week 13, twelve regions in BC, ON, QC & NS reported sporadic activity, while 41 regions reported no activity. One region in BC is not reporting until further notice. No influenza outbreaks were reported this week.

                  Overall Number of Influenza Outbreaks, Canada, by Report Week, 2009-2010



                  Note that this was the first year that all the provinces and territories were reporting on influenza outbreaks in schools (greater than 10% absenteeism on any day most likely due to ILI) which has increased considerably the total number of outbreaks reported compared to previous years.

                  ILI consultation rate
                  During week 13, the national ILI consultation rate was 12.9 consultations per 1,000 patient visits (see ILI graph) which was similar to the previous weeks and still remained below the expected range for this time of year (range from 18.2 to 30.4 consultations per 1,000 patient visits). All reporting provinces and territories had similar or lower ILI consultation rates compared to their respective ILI rates in the previous weeks. Those under 20 years of age still had the highest consultation rates: 33.2 per 1,000 among children under 5 years of age and 16.6 per 1,000 among those 5 to 19 years of age.

                  Laboratory Surveillance Summary
                  The proportion of tests that were positive for influenza during week 13 (0.32%, 6/1,858) was similar to the previous week and still remained at a low level for this time of year (see Tests table). Of the six positive specimens, four (67%) were positive for pandemic H1N1 2009 and two (33%) were unsubtyped influenza A. BC, ON and QC were the only provinces to report positive specimens. Note that since August 30, 2009, influenza A/H3N2 detections were highest in QC (85% or 44/52) and influenza B detections were highest in QC (43% or 9/21) and ON (57% or 12/21). Respiratory syncytial virus detections peaked during week 7 (28.3%), but were still high this week with a proportion of positive tests of 14.7%. Positive specimens for RSV were reported from all provinces (data not shown). The proportion of positive parainfluenza (3.1%) and adenovirus (1.6%) tests remained low during week 13.

                    Overall Influenza Summary - Week 14 (April 4 to April 10, 2010)

                    Overall influenza activity has remained low for at least 16 consecutive weeks. All influenza indicators were still below expected levels for this time of the year. The proportion of tests that were positive for influenza during week 14 (0.36%, 6/1,671) remained at a very low level for this time of year.
                    In week 14, one region (in NS) reported localized activity, ten regions (in BC, AB, ON & QC) reported sporadic activity, and 35 regions reported no activity. Eight regions (in BC, SK and NL) did not report this week. One influenza outbreak was reported in a long-term care facility in NS this week.

                    Note that this was the first year that all the provinces and territories were reporting on influenza outbreaks in schools (greater than 10% absenteeism on any day most likely due to ILI) which has increased considerably the total number of outbreaks reported compared to previous years.

                    ILI consultation rate
                    During week 14, the national ILI consultation rate was 9.1 consultations per 1,000 patient visits (see ILI graph) which was similar to the previous weeks and still remained below the expected range for this time of year (range from 17.4 to 25.3 consultations per 1,000 patient visits). All reporting provinces and territories had similar or lower ILI consultation rates compared to their respective ILI rates in the previous weeks except for YT and NT. Those in the 5 to 19 age group had the highest consultation rates (21.7 per 1,000) followed by those 65 years and over (11.3 per 1,000).

                    Laboratory Surveillance Summary
                    The proportion of tests that were positive for influenza during week 14 (0.36%, 6/1,671) was similar to the previous week and still remained at a low level for this time of year (see Tests table).Of the six positive specimens, three (50%) were positive for pandemic H1N1 2009, two (33%) were unsubtyped influenza A and 1 (17%) was influenza B. BC, AB, ON and NS were the only provinces to report positive specimens. Note that since August 30, 2009, influenza A/H3N2 detections were highest in QC (85% or 44/52) and influenza B detections were highest in QC (41% or 9/22) and ON (55% or 12/22). Respiratory syncytial virus detections peaked during week 7 (28.3%) continued to decline progressively to 13.0% this week. The proportion of positive parainfluenza (2.6%) and adenovirus (1.7%) tests remained low during week 14.

                      Overall Influenza Summary - Week 15 (April 11 to April 17, 2010)

                      Overall influenza activity continued to be low for at least 17 consecutive weeks. The proportion of tests that were positive for influenza during week 15 (0.07%, 1/1,379) continued to decline and remained at a very low level for this time of year.
                      In week 15, eleven regions (in BC, AB, ON, QC, NB & NS) reported sporadic activity and 39 regions reported no activity. One region in BC and all three regions in SK are not reporting for the remainder of the season. No influenza outbreaks were reported this week.

                      Note that this was the first year that all the provinces and territories were reporting on influenza outbreaks in schools (greater than 10% absenteeism on any day most likely due to ILI) which has increased considerably the total number of outbreaks reported compared to previous years.

                      ILI consultation rate
                      During week 15, the national ILI consultation rate was 9.3 consultations per 1,000 patient visits (see ILI graph) which was similar to the previous weeks and still remained below the expected range for this time of year (range from 15.3 to 28.0 consultations per 1,000 patient visits). All reporting provinces and territories had similar or lower ILI consultation rates compared to their respective ILI rates in the previous weeks. Those over 65 years of age had the highest consultation rates (20.8 per 1,000) followed by those in the 5 to 19 age group (11.8 per 1,000).

                      Laboratory Surveillance Summary
                      The proportion of tests that were positive for influenza during week 15 (0.07%, 1/1,379) was lower compared to the previous week and remained at a very low level for this time of year (see Tests table).The positive specimen was reported as pandemic H1N1 2009. NS was the only province to report positive specimens. Note that since August 30, 2009, influenza A/H3N2 detections were highest in QC (85% or 44/52) and influenza B detections were highest in ON (52% or 12/23) and in QC (39% or 9/23). Respiratory syncytial virus detections peaked during week 7 (28.3%) and continued to decline progressively to 12.2% this week. Positive specimens for RSV were reported from all provinces (data not shown). The proportion of positive parainfluenza (3.8%) and adenovirus (1.9%) tests remained low during week 15.

                        Overall Influenza Summary - Week 16 (April 18 to April 24, 2010)

                        Overall influenza activity continued to be low for at least 18 consecutive weeks. Only two specimens (out of 1,713) tested positive for pandemic H1N1 2009 this week. The specimens were from ON and QC. Respiratory syncytial virus detections have been high since the beginning of 2010. However, the proportion of positive RSV (8.7%) continued to decline for the last 9 weeks.
                        In week 16, eleven regions (in BC, AB, ON, QC, NB & NS) reported sporadic activity and 39 regions reported no activity. One region in BC, and all three regions in SK are not reporting for the remainder of the season. No influenza outbreaks were reported this week.

                        Overall Number of Influenza Outbreaks, Canada, by Report Week, 2009-2010



                        Note that this was the first year that all the provinces and territories were reporting on influenza outbreaks in schools (greater than 10% absenteeism on any day most likely due to ILI) which has increased considerably the total number of outbreaks reported compared to previous years.

                        ILI consultation rate
                        During week 16, the national ILI consultation rate was 12.1 consultations per 1,000 patient visits (see ILI graph) which was similar to the previous weeks and still remained below the expected range for this time of year (range from 13.6 to 26.1 consultations per 1,000 patient visits). All reporting provinces and territories had similar or lower ILI consultation rates compared to their respective ILI rates in the previous weeks. Children under 5 years of age had the highest consultation rates (30.2 per 1,000) followed by those over 65 years of age (10.6 per 1,000).

                        Laboratory Surveillance Summary
                        The proportion of tests that were positive for influenza during week 16 (0.12%, 2/1,713) was similar compared to the previous week and remained at a very low level for this time of year (see Tests table).The positive specimens were reported as pandemic H1N1 2009. ON and QC were the only provinces to report positive specimens. Note that since August 30, 2009, influenza A/H3N2 detections were highest in QC (85% or 44/52) and influenza B detections were highest in ON (52% or 12/23) and in QC (39% or 9/23). Respiratory syncytial virus detections peaked during week 7 (28.3%) and continued to decline progressively to 8.7% this week. Positive specimens for RSV were reported from all provinces (data not shown). The proportion of positive parainfluenza (3.8%) and adenovirus (1.8%) tests remained low during week 16.

                          Overall Influenza Summary - Week 17 (April 25 to May 1, 2010)

                          Overall influenza activity continued to be low for at least 19 consecutive weeks. Only four specimens (out of 1,500) tested positive for influenza this week, and all were pandemic H1N1 2009. The specimens were from ON and BC. Respiratory syncytial virus detections have been high since the beginning of 2010. However, the proportion of positive RSV (6.8%) continued to decline for the last 10 weeks.
                          In week 17, eight regions (in BC, AB, ON, QC, NB & NS) reported sporadic activity and 42 regions reported no activity. One region in BC, and all three regions in SK are not reporting for the remainder of the season. No influenza outbreaks were reported this week.

                          Note that this was the first year that all the provinces and territories were reporting on influenza outbreaks in schools (greater than 10% absenteeism on any day most likely due to ILI) which has increased considerably the total number of outbreaks reported compared to previous years.

                          ILI consultation rate
                          During week 17, the national ILI consultation rate was 5.4 consultations per 1,000 patient visits (see ILI graph) which is below the expected range for this time of year (range from 9.5 to 33.9 consultations per 1,000 patient visits) and is the lowest observed this season to date. Children under 5 years of age had the highest consultation rates (18.4 per 1,000) while the rest of the age groups had rates between 4.5 and 4.7 per 1,000.

                          Laboratory Surveillance Summary
                          The proportion of tests that were positive for influenza during week 17 (0.27%, 4/1,500) was similar compared to previous weeks and remained at a very low level for this time of year (see Tests table).The positive specimens were all pandemic H1N1 2009. ON and BC were the only provinces to report positive specimens this week. Note that since August 30, 2009, influenza A/H3N2 detections were highest in QC (85% or 44/52) and influenza B detections were highest in ON (52% or 12/23) and in QC (39% or 9/23). Respiratory syncytial virus detections peaked during week 7 (28.3%) and continued to decline progressively to 6.8% this week. Positive specimens for RSV were reported from all provinces except PEI (data not shown). The proportion of positive parainfluenza (5.0%) and adenovirus (1.9%) tests remained low during week 17.

                            Overall Influenza Summary - Week 19 (May 9 to May 15, 2010)

                            Overall influenza activity has remained low since the beginning of 2010. Only two specimens (out of 1,365) tested positive for influenza this week. The two positive specimens were reported as influenza type B.
                            In week 19, six regions (in BC, AB, ON & QC) reported sporadic activity and 44 regions reported no activity. Four regions (1 in BC and all 3 in SK) have stopped reporting for the remainder of the season. No influenza outbreaks were reported this week.

                            Overall Number of Influenza Outbreaks, Canada, by Report Week, 2009-2010



                            Note that this was the first year that all the provinces and territories were reporting on influenza outbreaks in schools (greater than 10% absenteeism on any day most likely due to ILI) which has increased considerably the total number of outbreaks reported compared to previous years.

                            ILI consultation rate
                            During week 19, the national ILI consultation rate was 11.1 consultations per 1,000 patient visits (see ILI graph) which was within the expected range for this time of year (range from 8.9 to 13.8 consultations per 1,000 patient visits). All reporting provinces had similar or lower ILI consultation rates compared to their respective ILI rates in the previous weeks except the three territories which had a slightly higher rate this week. Children under 5 years of age had the highest consultation rates (24.7 per 1,000) followed by those between 5 and 19 years of age (14.7 per 1,000).

                            2009-2010 compared to 1996/97 through to 2008/09 seasons




                            Note: No data available for mean rate in previous years for weeks 19 to 39 (1996-1997 through 2002-2003 seasons).
                            Delays in the reporting of data may cause data to change retrospectively.
                            Laboratory Surveillance Summary
                            The proportion of tests that were positive for influenza during week 19 (0.15%, 2/1,365) was similar compared to the previous weeks and remained at a very low level for this time of year (see Tests table). The two positive specimens were reported as influenza type B, one from BC and one from AB. Respiratory syncytial virus detections peaked during week 7 (28.3%) and continued to decline progressively to 6.0% this week. Positive specimens for RSV were reported from all provinces except NS, PE and NL (data not shown). The proportion of positive parainfluenza tests (5.6%) has been slightly higher for the past three weeks, especially in AB, MB and ON.

                              During week 20, the national ILI consultation rate was 5.8 consultations per 1,000 patient visits (see ILI graph) which was almost within the expected range for this time of year (range from 6.0 to 16.1 consultations per 1,000 patient visits). All reporting provinces had similar or lower ILI consultation rates compared to their respective ILI rates in the previous weeks. Children under 5 years of age had the highest consultation rates (60.2 per 1,000) followed by those between 5 and 19 years of age (43.7 per 1,000).

                              2009-2010 compared to 1996/97 through to 2008/09 seasons




                              Note: No data available for mean rate in previous years for weeks 19 to 39 (1996-1997 through 2002-2003 seasons).

                              Laboratory Surveillance Summary
                              The proportion of tests that were positive for influenza during week 20 (0.24%, 3/1,260) was similar compared to the previous weeks and remained at a very low level for this time of year (see Tests table). Of the three positive specimens, one was positive for influenza A/H3N2, one was unsubtyped influenza A and one was positive for influenza B. AB and ON were the only provinces to report positive influenza specimens this week. The proportion of positive parainfluenza tests (8.9%) remained high especially in AB, MB and ON while respiratory syncytial virus (RSV) detections continued to decline to 5.9% this week.

                                Summary of FluWatch Findings for the
                                Week ending June 19, 2010
                                • Overall influenza activity has remained low since the beginning of 2010. All influenza indicators in Canada were still below expected levels for this time of the year.
                                • Two specimens (out of 1,851) in weeks 23-34 tested positive for influenza. Of the two positive specimens, one was positive for pandemic H1N1 and one was positive for influenza B. For weeks 23 and 24 combined, the proportion of positive parainfluenza tests (8.4%) remained high especially in AB and ON while low levels of respiratory syncytial virus (RSV) (2.6%) and adenovirus detections (2.1%) continue to be reported.
                                • Overall pandemic influenza activity remained low worldwide as of June 13, 2010, with geographically limited circulation of pandemic influenza virus in parts of the tropics, particularly in parts of Central America and the Caribbean and in parts of South and Southeast Asia.

                                Overall Influenza Summary - Week 23 & 24 (June 6 to June 19, 2010)

                                Overall influenza activity has remained low since the beginning of 2010. The proportion of tests that were positive for influenza during weeks 23-24 (0.11%) was similar compared to the previous weeks and remained at a very low level for this time of year.
                                In week 23, four regions (in AB, ON & QC) reported sporadic activity and 46 regions reported no activity. In week 24, three regions (in AB, ON & QC) reported sporadic activity and 47 regions reported no activity. Four regions (1 in BC and all 3 in SK) have stopped reporting for the remainder of the season. No influenza outbreaks were reported in weeks 23-24.

                                During weeks 23 and 24, the national ILI consultation rates (5.3 and 7.1 per 1,000 consultations, respectively) remained low and were within expected levels for this time of year (see ILI graph). All reporting provinces had similar or lower ILI consultation rates compared to their respective ILI rates in the previous weeks. Children under 5 years of age had high consultation rates (13.6 and 13.5 per 1,000 in weeks 23 to 24, respectively) as well as those between 5 and 19 years of age (6.4 and 14.8 per 1,000).

                                The proportion of tests that were positive for influenza during week 23 was 0.14% (1/705) and during week 24 was (0.09%, 1/1,146) with a combined proportion of 0.11% (2/1,851) and remained at a very low level for this time of year (see Tests table). Of the two positive specimens, one was positive for pandemic H1N1 and one was positive for influenza B. AB and QC were the only provinces to report positive influenza specimens during those reporting weeks. For weeks 23 and 24 combined, the proportion of positive parainfluenza tests (8.4%) remained high especially in AB and ON while low levels of respiratory syncytial virus (RSV) (2.6%) and adenovirus detections (2.1%) continue to be reported.
