From my experience, I have always gotten the flu, or some kind of sickness, after the cold months, as it turns into spring and summer.

When a warmer spring month rolls around, I think that I must’ve escaped getting sick with the flu, then, bam!, I get hit with it, and get knocked out for a few days.

The annoying flu is during the summer, when it’s hot, and you’re sick, so you just become more miserable.
