Norovirus Infection


Norovirus infection is usually diagnosed based on symptoms, although it can be confirmed by detecting noroviruses in a stool sample. If you have a weakened immune system or other medical conditions, your doctor might recommend a stool test to confirm the presence of norovirus.


There is no specific treatment for norovirus infection. Recovery largely depends on the health of your immune system. For most people, the illness resolves within a few days.

Your doctor might recommend over-the-counter anti-diarrheal medication and medications to relieve nausea. It’s important to replace lost fluids. Oral rehydration solutions can be helpful. If you’re unable to drink enough fluids to prevent dehydration, intravenous fluids may be required.
