If you are young, young, youuuung, then you'll be fine. I'm talking like like ten and below. But any older, and you should be very concerned. Adults can easily die from chicken pox. I'm not trying to scare you, just trying to warn you. And teenagers and such can get VERY sick from it, even hospitalized. The nasty thing about chicken pox is the older you are, the worse you will be affected by it.I would definitely try to stay somewhere else until he is recovered. And KEEP HIM QUARANTINED. I know, that sounds mean. But it's for your, and other peoples, health reasons.http://kidshealth.org/parent/infections/bacterial_viral/chicken_pox.html#Basically, stay FARRRR away from him, and make no contact with things he has touched even.
