National Flu Activity
Central Flu Activity
- In week 06, all influenza indicators declined from, or remained similar to, the previous week.
- Influenza activity in the Central and the Atlantic Provinces continued into week 06 (mainly due to influenza A) while activity in the Western provinces and the Territories declined.
- For the past few weeks, influenza B detections have been increasing steadily, particularly in the Prairies and in Quebec.
- A(H3N2) continues to be the most common type of influenza affecting Canadians. Seniors continue to have the highest number of positive laboratory detections, hospitalizations and deaths.
- Detections of respiratory syncytial virus (RSV) continue to be the second most frequently detected virus after influenza.
- Evidence from the National Microbiology Laboratory (NML) does indicate that this year's vaccine will continue to provide protection against the circulating A(H1N1) and B strains.

About the Active Weather Trigger
Active weather triggers are changes in the weather that could augment health complaints. Each active weather trigger is weighted equally. The occurrence of more than one trigger increases the severity of health risk.
Temperature – a decrease of 5 degrees Celsius or more.
Humidity – an increase of 20%.
Pressure – a decrease of 0.7 kPa (kilopascal) or more.
Dewpoint – an increase of 5 degrees Celsius or more.
