Viral Infections....Symptoms and Prevention of Spreading Viral  infections usually resolve on their own without antibiotics. The most common symptoms of a viral infection are diarrhea, vomiting, and/ or a low grade fever (99.5-101.0). This type of infection is easily spread from one child to another. The best way to prevent the spread is good hand washing and to keep the infected person out of the general population until they are free of all symptoms. If your child has any of the following symptoms - upset stomach, vomiting, diarrhea, and/or fever, please keep them at home until they are 24 hours symptom free. If these symptoms last more than three days, you may need to contact your health care professional (doctor or nurse)
