I think I have the flu. How long should I stay home from school? –
Staying home as soon as you notice flu symptoms is the best way to stop the
flu from spreading. It's also best for your health: Resting might help you recover
People who have the flu should stay home until at least 24 hours after
their fever has gone away on its own (without the help of fever-reducing medicines).
Of course, if you still don't feel better even after your fever is gone, you'll want
to keep resting until you do.
If it seems like you're taking a long time to get well, or if you're having trouble
breathing, call your doctor.
