How long should I stay home if I have h1n1?

Yesterday I went to the doctor, and they said that because I have all the symptoms of a flu at this time of year (which is unusual) that they are going to treat me for swine flu or H1N1. I was wondering how long I should stay home after the fever has ped. I should also add that I am 11 and I'm attending a fairly crowded school.and thank you!
