Cumulative total for the season, as of



The flu season runs from October into May. It isn’t clear why flu is seasonal. It is probably a combination of cold weather forcing people into close proximity indoors and cold dry air which seems to make transmission of the virus easier and also to prevent humans from fighting off the flu.

About two-thirds of the people who have contracted confirmed flu this season in Maine are women. The youngest Mainer with a confirmed case of the flu is 1 month old and the oldest is 100. There have been 211 hospitalizations associated with flu this season, 53 in the last week alone.
