Stomach flu

Other names: Gastroenteritis, viral


Viral gastroenteritis is an intestinal infection marked by watery diarrhea, abdominal cramps, nausea or vomiting, and sometimes fever. The most common way to develop viral gastroenteritis is through contact with an infected person or by ingesting contaminated food or water.




Dehydration is the main complication of viral gastroenteritis, especially in infants, older adults, and immunocompromised individuals.


Prepare a list of questions for your doctor and expect questions about symptoms and possible contacts with infected individuals.


Diagnosis is usually based on symptoms and physical exam. Rapid stool tests can detect specific viruses like Rotavirus or Norovirus.


There's no specific medical treatment for viral gastroenteritis. Antibiotics are not effective against viruses.
