Gastroenteritis in Children
What is gastroenteritis?
Gastroenteritis is an infection of the digestive (also called the gastrointestinal, or GI) tract that causes throwing up, diarrhea, or both. The stomach and intestines are the main organs of the digestive tract. People sometimes make the mistake of calling gastroenteritis "stomach flu." But it isn't a "flu" and has nothing to do with influenza (flu).

Children with gastroenteritis throw up and have diarrhea, belly cramps, and fever

What causes gastroenteritis?
Gastroenteritis is most often caused by a virus (such as rotavirus). It can also be caused by bacteria or parasites.
Children can get gastroenteritis by:
-
Touching infected children or their toys, and then putting their fingers in their mouth
-
Being near a sick child who is sneezing or spitting
-
Eating food or drinking liquid that has bacteria in it (this is called food poisoning)
-
Drinking unpasteurized milk or juice (unpasteurized means it wasn't heated to kill germs)
-
Touching reptiles, birds, frogs, or salamanders that carry bacteria
-
Eating certain plants or medicines
-
Swallowing infected water from swimming pools, water parks, or streams

-
In a 24-hour period, your child should drink at least 1½ ounces of fluid for every pound of body weight
-
If your child has diarrhea, give more fluid than usual
