What is considered the maximum amount oftime to pass to know that you will NOT come down with SV* symptoms? I know it has alot to do with what strain of virus and I see a typical incubation period of 24-48 hours (as little as 4-12 hours). My daughter was v* on Monday morning from 2am-6am and made a fast recovery within a 24 hour period. We all ate the same thing over the weekend and my oldest son who lives with us has been symptom free as well so far. When could I consider myself to be "out of the woods"! It's driving me crazy and Im scared to eat tomorrow (Thanksgiving) because of this dreaded phobia!!
