FluWatch is Canada's national surveillance system that monitors the spread of flu and flu-like illnesses. FluWatch reports with information on flu activity are published on Fridays. They're published weekly during active flu season and monthly during the summer.
Weekly Respiratory Virus Detections report
The Respiratory Virus Detection Surveillance System monitors laboratory testing for flu, COVID-19, respiratory syncytial virus (RSV) and other respiratory viruses. Laboratories across Canada report the number of tests performed and the number of positive tests each week.
Reports are posted every Thursday and contain data on laboratory testing for flu, COVID-19, RSV and other respiratory viruses in Canada.
Annual FluWatch report
Summary FluWatch reports with information on flu activity in Canada for the previous year's flu seasons are posted every year.
Current flu activity in Canada
Maps of weekly flu activity in Canada by region. The current flu activity map shows flu activity levels reported by each region. The FluWatchers map shows where flu-like-illness is being reported by participants in the FluWatchers program.
Become a FluWatcher
FluWatchers are Canadian volunteers who report on symptoms such as cough and fever. This information helps public health officials identify where flu, COVID-19 and other respiratory viruses may be circulating.
The main weekly questionnaire has 2 health-related questions and only takes about 15 seconds to complete. Your answers are anonymous.
Become a FluWatch sentinel practitioner
The Sentinel Primary Care Influenza-like-illness Surveillance program is FluWatch's primary source for outpatient flu monitoring data in Canada.
Physicians, nurse practitioners and registered nurses who are involved in primary care are eligible to become FluWatch sentinel practitioners.
