Ontario Influenza Bulletin

Each influenza season, PHO collates and analyzes information provided by health units and publishes it weekly in the Ontario Influenza Bulletin. The bulletin summarizes clinical information, results of laboratory respiratory virus testing, ILI surveillance information and reports of institutional respiratory infection outbreaks for the current week and for the season.

Note: Effective November 2, 2012, Public Health Ontario is introducing a new weekly report: the Ontario Respiratory Virus Bulletin. The Ontario Respiratory Virus Bulletin combines information formerly published separately in the Ontario Influenza Bulletin and Laboratory-Based Respiratory Pathogen Surveillance Report.
