What are the symptoms of gastroenteritis in children?

Gastroenteritis happens when the stomach and lining of the intestines are irritated. In the first 12 to 48 hours (the first phase) of gastroenteritis, the child usually becomes sick suddenly with:
  • low-grade fever (100 degrees F/38 degrees C)
  • frequent, forceful diarrhea
  • bowel movements that are watery, foul smelling, and usually green
  • vomiting
  • sometimes a cough and a runny nose
After the first 12-48 hours the child may have:
