when does flu season end in us
Flu Season. Flu season is the time of year when you are most likely to get sick from the flu. In general, flu season can start anytime in late fall, peak in mid-to-late winter (usually January or February), and continue through early spring. On average, flu season lasts about 13 weeks. It will usually end by April, but in some years it can linger into May. There have been six years in the past where the peak was in March, for example.
