May 10, 2009 to May 16, 2009 (Week 19)
Overall influenza activity decreased slightly from previous week
During week 19 the reported activity level, consultations rates, number of new outbreaks and proportions of positive tests decreased. Ten regions in BC, AB, SK, ON & NF reported localized activity, 33 regions sporadic activity in BC, AB, SK, MB, ON, QC, NB, PE, NS, NL, YK, NWT & NU and 10 regions in MB, ON, NB, NS, NWT & NU reported no activity (see map). This week, the ILI consultation rate decreased to 15 consultations per 1,000 patient visits (see ILI graph) which is within the expected range for this time of year. The sentinel response rate was 52.4%. The proportion of tests that were positive for influenza was 4.1% which is similar to the two previous weeks (see table). The majority (62.9%) of influenza virus detections this season have been for influenza A. Seven new influenza outbreaks were reported this week; three were in LTCFs (BC, AB, SK), three were in schools (BC, AB, SK) and one occured in unspecified locations in AB.
H1N1 Flu Virus (Human Swine Flu)
As of May 20, 2009 (15:00 EDT), a total of 719 laboratory-confirmed cases of the H1N1 Flu Virus (Human Swine Flu) were reported from all but three jurisdictions in Canada (NL, NU, and NWT). Among cases with information available, (n=650), the median age was 21 years and 406 (62.5%) were between 10-29 years of age. Thirty-one (4.7%) cases were 0-4 years, 63 (9.7%) cases were 5-9 years of age, and 5 (0.8%) were >=65 years old. Typically influenza illness is observed in the very young (0-4 years) and older (>=65 years) age groups. Information on travel history was not available for 105 cases (16.2%) and of the remaining 545 cases, 161 (29.5%) reported a history of travel in the 7 days prior to symptom onset while 384 (70.5%) did not. Information on hospitalizations was available for 299 cases of which 17 cases (5.7%) had been hospitalized [BC (3; 18%), AB (4; 24%), MB (1; 6%), ON (7; 41%), and QC (2; 12%)]. The median age of hospitalized cases was 25 years compared to 17 years among non-hospitalized cases and 21 years among all reported cases. Globally there have been 11,168 cases of Influenza A (H1N1) and 86 deaths reported in 42 countries.
