Currently, there is no antiviral medication that works against norovirus and there is no vaccine to prevent infection. Norovirus infection cannot be treated with antibiotics because antibiotics are not effective against viruses.
If you are ill with vomiting and diarrhea, stay home and stay hydrated with plenty of fluids.
Dehydration is the most serious health effect that can result from norovirus infection. By drinking oral rehydration fluids (ORF), juice, or water, you can reduce your chance of becoming dehydrated. Sports drinks are an effective supplement for rehydration but should not be used alone since they are low in sodium and potassium.
If you can't keep down any fluids and are feeling very thirsty or lightheaded, please see your health care provider.
