Diarrhea, on the other hand, can last up to two weeks, especially in the case of infants. Unless the diarrhea is severe and the child isn't consuming plenty of fluids, the condition will probably abate on its own. Otherwise, consult a physician. Children experiencing either vomiting or diarrhea should be kept home, away from other children. If a child becomes dehydrated despite a parent's best efforts, a physician should be consulted immediately.
Treatment usually begins with the physician's efforts to get the child to consume liquids orally.
If this is ineffective, the child can receive fluids intravenously.
