The only thing you can really predict about the flu season is its unpredictability. The viruses constantly morph, severity can exceed expectations or not reach them, and the season’s onset can be early, late, or right on schedule. Although activity typically peaks in January or February, the season can begin in October and drag on until May.
But there is one thing you can predict about getting the flu: If you do come down with it, it will be at the worst possible time — the holidays, right before a big date, or when you need to pull an all-nighter and cram for an exam.
