Summary of FluWatch Findings for the
Week ending June 13, 2009
Overall influenza activity increased this week, in particular for rates of visits to healthcare professionals for ILI consultations and proportion of tests positive for influenza
As of 17 June, 2009, all provinces and territories reported a total of 4,905 laboratory-confirmed cases of H1N1 flu virus including 298 hospitalizations and 12 deaths to the Public Health Agency of Canada (PHAC). In the last week (11-17 June, 2009), the number of cases continued to increase mainly in four provinces (AB, MB, ON and QC) and one territory (NU).
However, even if overall there is an increase in transmission, illness from the H1N1 flu virus in Canada has been mild thus far.
Of those hospitalized cases, more than 50% were reported this week. Children less than 10 years were particularly affected, accounting for almost a third of the hospitalized cases. Based on a proportion of hospitalized cases for whom the information was provided, 35% of the cases had one or more underlying medical condition (including pregnancy). Eight deaths, two in Manitoba and six in Quebec were reported this week.

As of 17 June, 2009, all provinces and territories have reported a total of 4,905 laboratory-confirmed cases of H1N1 flu virus, of which 298 H1N1 cases were admitted to hospital. Cases were distributed similarly between males and females (48.6% for males, 50.9% for females, 0.5% unknown). These cases were from British Columbia (2.0%), Alberta (3.4%), Saskatchewan (2.0%), Manitoba (14.4%), Ontario (18.1%), Quebec (53.7%), Nova Scotia (0.3%) and Nunavut (6.1%). Of the 298 hospitalized cases, core data are available for 262 (87.9%) cases. The median age of the hospitalized cases was 18 years (range <1 to 85 years). Forty-nine (18.7%) of the hospitalized cases were reported to have been admitted to the intensive care unit (ICU). Information regarding underlying medical conditions was available for 85 hospitalized cases. Among theses, 30 cases (35%) have underlying medical conditions, including lung disease (8), diabetes (3), kidney disease (2), immune suppression (4) and chronic heart disease (5), and other underlyings conditions (16) (note that some cases reported more than one underlying condition). Two hospitalized cases were pregnant women, both in their 3rd trimester. There have been also 12 deaths reported since the beginning of the outbreak among the following age groups : 10 to 19 years (8.3%), 30 to 39 years (16.7%), 40 to 49 years (33.3%), 50 to 59 years (25.0%) and ≥ 60 years (16.7%). Eleven had underlying medical conditions and one was over age 65.

This week, the ILI consultation rate increased to 41 consultations per 1,000 patient visits (see ILI graph) which is comparable to the level observed during the seasonal influenza peak (week 9).
