Summary of FluWatch Findings for the
Week ending June 6, 2009
As of 10 June, 2009, 9 provinces and 3 territories have reported a total of 2,978 laboratory-confirmed cases of H1N1 flu virus including 149 hospitalizations and 4 deaths to the Public Health Agency of Canada (PHAC). In the last week (4-10 June, 2009), the number of cases has continued to increase mainly in 5 provinces (AB, SK, MB, ON and QC) and one territory (NU).
Overall illness from H1N1 flu virus in Canada has been mild thus far. Only 4.8% of laboratory-confirmed cases have been hospitalized.
Of those hospitalized cases, more than 35% were reported this week. Children less than 10 years were particularly affected, accounting for a third of the hospitalized cases. Based on a proportion of hospitalized cases for whom the information was provided, only a quarter of the cases had one or more underlying medical conditions (including pregnancy).
The World Health Organization (WHO) has raised the pandemic alert to Phase 6 on 11 June 2009. As of 10 June 2009, 74 countries worldwide have officially reported 27,737 cases of H1N1 flu virus, including 141 deaths, to WHO.
During week 22, overall activity level of influenza is higher than excepted at this time of the year with increased influenza virus detections and medical visits for influenza symptoms.
My comments:
Charts, graphs at link.
ILI is almost 30%; only weeks 4, 6, & 9 were higher than this level in the 08-09 season
There is a big spike in infl A detections, sitting around 25%, much higher than during the 'peak' of seasonal flu.
