What causes norovirus infection?
The main viruses that cause gastroenteritis used to be called "Norwalk-like viruses" because Norwalk is the most well-known virus in this group. Now the viruses are referred to as noroviruses. Noroviruses are not new, but interest in them is growing as researchers learn how frequently they make people sick. Norovirus infections are implicated in newsworthy descriptions of outbreaks on military and cruise ships and in hotels, restaurants, daycare centers, nursing homes, and hospitals. Decontamination of these places has proved to be challenging. Noroviruses are not related to bacteria or parasites that also can cause gastrointestinal illnesses.
Who is at highest risk?
Diagnosis
Your healthcare provider can use laboratory tests to diagnose norovirus infection, but these tests are not used routinely. Usually, your healthcare provider will diagnose it by examining you and noting your symptoms.
When to seek urgent medical care?
Treatment options
The best treatments for norovirus infection are to get plenty of bed rest and drink lots of fluids. To prevent dehydration (severe loss of body fluids), your healthcare provider may give you specific instructions about the type of fluids you should drink. You should not take antibiotics for norovirus infection because they have no effect on viruses. If your infant or child has diarrhea, you should contact a healthcare provider immediately for treatment advice.
