There is no medicine that will kill a norovirus. Therefore, treatment for norovirus gastroenteritis is focused on providing supportive care while the body fights the norovirus. Supportive care involves treating symptoms, such as dehydration, that can occur as a result of the norovirus gastroenteritis.
Supportive care for norovirus gastroenteritis includes:
- Resting in bed
- Drinking plenty of fluids
- Taking medication (such as aspirin or acetaminophen) to relieve fever.

Norovirus gastroenteritis is usually not serious, although people may feel very sick and vomit many times a day. Most people get better within 1 or 2 days, and they have no long-term health effects related to their illness.
A person can be infected with norovirus more than once in his or her lifetime. This is because there are many different noroviruses, and being infected with one type does not prevent infection from another type later.
There is no vaccine to prevent norovirus gastroenteritis. Therefore, preventing norovirus gastroenteritis involves reducing your chances of coming in contact with noroviruses.
