What Causes Diarrhea in Small Children?

The main cause of diarrhea in children under 5 years of age is rotavirus, which causes gastroenteritis – inflammation of the inner layer of the stomach and small intestine.

Symptoms of Stomach Flu

Symptoms of rotavirus infection resemble influenza – from here the term stomach flu. There is no connection between stomach flu and influenza, though. Symptoms of stomach flu (viral diarrhea) include:

  • Fever, headache, followed by..
  • ..watery diarrhea and vomiting that appear 1-2 days after infection and usually last for 3-8 days (1).
  • Symptoms of dehydration: drowsiness or restlessness, thirst (which may not necessary be present!), decreased urination, or, in severe cases, sunken eyes, sunken fontanel, and decreased consciousness.
  • In the Western world, rotavirus diarrhea is usually a mild disease, but in some parts of Africa, Middle and South America and south Asia over 1 million of children dye from it each year, mainly from dehydration.
