Causes include bacteria, viruses, parasites, medications, functional disorders, and food sensitivities. Infection with the rotavirus is the most common cause of acute childhood diarrhea. Rotavirus diarrhea usually resolves in five to eight days. A vaccine to prevent rotavirus infection is now available for infants under six months of age. Medications to treat diarrhea in adults can be dangerous to children and should be given only under a physician's guidance.
Diarrhea can be dangerous in newborns and infants.
In small children, severe diarrhea lasting just a day or two can lead to dehydration. Because a child can die from dehydration within a few days, the main treatment for diarrhea in children is rehydration. Temperature above 101.4 degrees Fahrenheit. No improvement after 24 hours. If you suspect that you or your child is dehydrated, call a physician immediately.
