Acute infectious diarrhea in children.

Effective management of acute diarrheal disease depends on an understanding of the mechanisms and the pathogens responsible for diminished absorption of water from the intestines or increased secretion of water and electrolytes into the intestines. Initial therapy consists of fluid management, with hospitalization if dehydration is significant. Antibiotics are useful in treating specific disease entities, such as shigellosis. Careful attention to clinical status and follow-up is essential.
