Is the seasonal pattern of ordinary flu different for Florida than for most states?
No evidence suggests that Florida, or the American South in general, experiences peak flu season at a time different than the rest of the country.
As the Centers for Disease Control reports, influenza activity often first increases in October, peaks sometime between December and February, and can last “as late as May.” Flu season in Florida occurs in this same time period, “from October to May,” according to data on a website run by the state’s health department.
Nationwide, the CDC noted that flu activity in the 2020-2021 season was “unusually low,” probably because of the effect of widespread masking and social distancing measures taken to slow the spread of the coronavirus. In addition, the agency notes that “a record number of influenza vaccine doses” was distributed.
