Viral gastroenteritis is caused by one of several viruses that assault the intestines. The viruses are usually spread through contact with someone who is infected or with something he or she touched. Viral gastroenteritis also can spread through food or water that is contaminated.

Risk factors for viral gastroenteritis include:
The symptoms of viral gastroenteritis usually begin between 1 to 2 days after you’re exposed to the virus. The illness usually lasts 1 to 2 days, but it can rarely last for up to 10 days.
