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. If you're unable to drink enough fluids to prevent dehydration, you may need to receive fluids intravenously.

Your doctor also may recommend over-the-counter anti-diarrheal medication if you're under the age of 65.
