The flu season is winding down in Minnesota, but there is still some activity in the state. The Department of Health reported 15 influenza-related hospitalizations over the past week last week, along with one nursing home outbreak and one school outbreak. The geographic spread of the flu has moved from the “sporadic” classification to “local” now as well. State health officials say there’s been a slight increase in late season Influenza-B cases. The flu season in Minnesota typically lasts through the middle of May.
