Specializes in Internal Medicine

No: It is contagious by hand to mouth. You have to touch the vomit or diarrhea then touch an open area like your eye, nose, mouth, nose and then it is very contagious . That is why handwashing around a sick person is so important and disinfecting everything that person could have touched important .
