crud is everywhere. as far as i'm concerned the only reason you keep kids with chicken pox home is for the comfort of the child. you are contagious 3 days before the spots break out. 3 days before you have any idea you are sick. that being said i just spent 4 days in the hospital with some unknown gastrointestinal crud and who knows where i got that. no one i was around was sick that i know of. yes people should be considerate, however.......................
