I have 2 sm kids in daycare on thurs last week my 1yr came home vomit&diarrheano fever lasted18hours how long til i know the rest of us r clear?

Week or so : Usually these viruses have a 24 to 48 hour incubation period. However, I will say give it a week or two, because of the fact that these viruses live on surfaces for up to six months! Icky huh? So every little place your loves have been wipe down as best as you can. Wash your hands, don't touch your face, and hold your breath! Good luck! Hope this helps!
