In week 10, influenza activity in Canada continues to decrease overall, and is consistent with activity at this time in past influenza seasons.
The influenza A(H1N1) virus remains the most common influenza virus circulating this season. Circulation of influenza B virus continues to increase in recent weeks, resulting in increased paediatric and adult hospitalizations.
While the influenza A(H1N1) virus has mostly affected adults 20-64 years of age, influenza B cases are having a greater impact on adults 65 year of age and older.
As of week 10, 3,450 hospitalizations and 189 deaths have been reported from participating regions, which is comparable to reports in past influenza seasons.
