Viral Gastroenteritis

PUBLIC HEALTH FACT SHEET

What is Viral Gastroenteritis?
Gastroenteritis means inflammation of the stomach and intestines. Viral gastroenteritis is an infection caused by a virus that leads to vomiting and/or diarrhea. The viruses that can cause viral gastroenteritis include rotaviruses, enteric adenoviruses, and caliciviruses, which include the Norwalk-like viruses that are now referred to as Noroviruses.

How is it spread?
The viruses are spread through close contact with infected persons (for example, by sharing food, water, or eating utensils) and by touching surfaces contaminated by vomit or feces of ill persons.  People may also become infected by eating or drinking foods or beverages contaminated with a virus. 

How is it treated?
Treatment is to prevent severe loss of body fluids (dehydration).

  • For children, an oral rehydration fluid such as Pedialyte, Ceralyte, or Oralyte can be used.
  • Adults should drink clear liquids and avoid alcoholic and caffeinated beverages.
  • May need special medical attention if dehydration occurs.

How can we prevent the spread of Viral Gastroenteritis?
