The flu season in Kentucky lasts from November until May, and infections generally peak in January or February.But as of this week, the total number of infections reported hasn't matched previous seasons. State epidemiologist Dr. Kraig Humbaugh says that doesn't mean the flu has gotten any weaker."It's just slower in coming, but I don't think until the flu season's over we'll be able to say if it's a less severe season or not 'cause I don't think we've reached the peak yet," he says.Humbaugh says northeastern Kentucky has reported the most infections. The flu has forced two school districts in that region to cancel classes this week.
