Gastroenteritis is inflammation of the stomach and intestines, which leads to diarrhea and vomiting. Gastroenteritis is most often due to a bacterial or viral infection. Gastroenteritis that results from a virus is called viral gastroenteritis. Many different viruses cause gastroenteritis, including some rotaviruses, noroviruses, and adenoviruses. Viral gastroenteritis is contagious. Bacterial gastroenteritis is often caused by infection with E. coli and salmonella.
