Gastroenteritis, also called stomach flu, is an illness characterized by the inflammation of the gastrointestinal tract.

The disease can be caused by:

- Virus: rotavirus, norovirus, adenovirus, calicivirus, and astrovirus,

- Bacteria: mainly E. coli, Salmonella, Shigella and Campylobacter species,

- Parasites: Giardia lamblia, Entamoeba histolytica, and Cryptosporidium; and

- Others non-infectious causes: medications, foods intolerance or Crohn's disease can produce also inflammation of the gastrointestinal tract.

It can be spread by consumption of contaminated foods, water, or by contact with a sick person.

Rotavirus is the main cause of gastroenteritis in children and a full recovery is commonly expected within three to eight days. Norovirus is the leading cause of gastroenteritis among adults.

The “traveler's diarrhea” is usually a type of bacterial gastroenteritis. Symptoms usually start during the first 72 hours after the infection.

Bloody stool can be associated with bacterial infections.
Gastroenteritis, can be confirmed with a physical exam and a stool culture that helps to determine the type of organism causing the infection.
