Influenza Activity, Surveillance and Reports
The New York State Department of Health (NYSDOH) collects, compiles, and analyzes information on flu activity year-round in New York State (NYS), and produces a weekly report during the flu season (October through the following May).
In view of persisting elevated influenza activity throughout NYS, NYSDOH is extending the surveillance season beyond May until influenza activity has decreased.
