Gastroenteritis Norwalk Overview

Another name for Gastroenteritis Norwalk is Norwalk Virus Infection.

What is a Norwalk virus infection?
A person with a Norwalk virus infection or Norovirus infection has a viral infection of the stomach and intestines. The infection causes inflammation of the lining to the stomach and intestine, which results in diarrhea, vomiting, and fever. Norwalk virus infection is an intestinal illness that often occurs in outbreaks. It is contagious because the viruses are passed in the stool of infected persons. People are infected with Norwalk virus by swallowing food or water that has been contaminated with stool from an infected person. Outbreaks in the United States are most common in those who eat raw shellfish, especially oysters and clams.

What are the symptoms of a Norwalk virus infection?
Common symptoms of a Norwalk virus infection include cramping abdominal pain, fever, nausea and vomiting. Diarrhea is the most common symptom and stools may be watery, bloody, or contain yellow or green mucus. Symptoms of dehydration may be present.

How does the doctor treat a Norwalk virus infection?
Treatment for most forms of a Norwalk virus infection is supportive as antibiotics provide no benefit. General treatment includes clear liquid diet, hydration, and fever control.
