Norovirus is a highly contagious virus that can be transmitted from an infected person, contaminated food or water or by touching surfaces contaminated with the virus. The disease manifests itself in abdominal pain, nausea, diarrhea and vomiting following inflammation of the stomach and intestines. There is always a risk of dehydration, especially for young children and the elderly.

This virus is now considered the leading cause of gastroenteritis in the United States.

Symptoms manisfest 12 to 48 hours after contact with the virus. Most people feel better after 1 to 3 days. Note that the virus remains in the stool of the infected person for 2 weeks or more after the symptoms end and thus remains a risk of spread.


Travellers to restricted areas with high numbers of people are at greater risk of contracting this type of virus. For example, people travelling on cruise ships are particularly at risk.
