Noroviruses are the most common of the viruses that cause gastroenteritis. The usual symptoms of gastroenteritis include diarrhea, vomiting, nausea, and stomach pain. There is no specific treatment for this illness and most individuals recover in 1 to 3 days. The illness can last longer and be more severe in young children, older persons, or persons who have other health conditions.

The virus is highly contagious and can spread rapidly. A person can become ill by ingesting the virus from contaminated food or water or by close contact with someone who is ill. Touching surfaces or objects that are contaminated with norovirus, and then transferring the virus hand to mouth is another common way of becoming infected.

The best way to protect yourself from norovirus is to follow the prevention tips above, as no vaccine can prevent this illness at this time. Drinking plenty of water is very important with all diarrheal illnesses due to the fluid loss that occurs while ill.
