On week 50, low levels of influenza activity were reported across Canada and all the influenza indicators had declines for at least five consecutive weeks.
The ILI consultation rate was below the expected range for this time of the year and only 3.7% of the specimens tested were positive for influenza. The Pandemic (H1N1) 2009 strain still accounted for nearly 100% of the positive influenza A subtyped specimens this week.
The number of hospitalized cases (79 vs. 159), ICU admissions (21 vs. 40) and deaths (11 vs. 21) reported this week are about half of those reported last week, and approximately one quarter of those reported two weeks ago (week 48). Among reporting provinces and territories (PTs) this week, deaths were from BC, AB, SK, ON & QC.
From August 30 to December 19, 2009, a total of 6,951 hospitalized cases including 1,113 (16.0%) cases admitted to an intensive care unit (ICU) as well as 324 (4.7%) deaths had been reported.
