Treatment

There's no specific treatment for norovirus infection, and recovery generally depends on the health of your immune system. In most people, the illness usually resolves within a few days.

It's important to replace lost fluids. Oral rehydration solutions may be used. If you're unable to drink enough fluids to prevent dehydration, you might need to receive fluids through a vein.

Your doctor also might recommend over-the-counter anti-diarrheal medication.
