The viruses that cause the stomach flu (viral gastroenteritis) are present in the feces and vomit of the sick person. Illness is spread when a few of these viruses accidentally get into someone else's mouth. Hand washing is extremely important to avoid spreading the illness. Stay away from other people as much as possible while you are contagious. Do not prepare food for other people while you are contagious. Contagious food service providers (cafeteria or restaurant workers) are often responsible for outbreaks of the stomach flu. The viruses that cause gastroenteritis can live for weeks on surfaces. Clean contaminated surfaces with a solution of 10% household bleach in water or disinfect with Lysol Disinfectant spray. Both bleach and Lysol disinfectant spray kill this type of virus. Keep young children home from day care or preschool for 72 hours after symptoms have stopped to avoid starting an outbreak at your school.
