I forget all the rules to follow when someone you know has had a stomach virus (except for the obvious, wash your hands, don't touch your face and don't eat anything from their house). I'm moving to California on March 1st and won't get much of a chance to see him and his wife again after I move. On March 6th he posted on Facebook about how he was up all night vomiting and is pretty sure he got it from a couple of coworkers. I haven't a clue if his wife or his 2 children had it, but I'm wondering just how safe I am visiting 10 or 11 days later? Is there a chance for infection still? I hate having this phobia mess with friends I may not see for a very long time, but on that same token I really don't need to catch something like a stomach bug before my big move. Any advice?
