Become a FluWatcher
FluWatchers are Canadian volunteers who normally track influenza-like illness (ILI), but with the global pandemic, they're also tracking COVID-19-like illness (CLI).
By tracking symptoms, you can help public health officials identify where influenza and COVID-19 may be circulating. Just answer 2 quick health-related questions each week.
It only takes about 15 seconds to complete and your answers are anonymous.
Influenza-like illness (IL) definition
Acute onset of respiratory illness with fever and cough and one or more of the following: sore throat, arthralgia, myalgia or prostration, which could be due to influenza virus.
- In children under 5, gastrointestinal symptoms may also be present.
- In patients under 5 or 65 and older, fever may not be prominent.

Weekly Respiratory Virus Detections report
The Respiratory Virus Detection Surveillance System monitors laboratory testing for flu and other respiratory viruses. Select laboratories across Canada report the number of tests performed and the number of tests positive each week.
