A norovirus infection is the most common cause of gastroenteritis in the United States. An infection with norovirus is sometimes referred to as stomach flu, although this term is misleading because it is not an influenza infection.
Signs and symptoms of a norovirus infection are
- nausea,
- vomiting,
- abdominal or stomach pain, and
- watery diarrhea.
Other associated symptoms can include a
- low-grade fever,
- malaise, and
- muscle pain.
Norovirus infection is very contagious. When complications occur, these are related to the effects of dehydration and fluid loss. In most cases, the symptoms of a norovirus infection last for about 3 days.
Cause of a norovirus infection
People acquire norovirus infections by consuming foods contaminated with small amounts of infected fluids or stool. Foods and drinks may become contaminated during processing or handling by an infected person.
