Prevent Norovirus | CDC

Wash your hands often with soap and water for at least 20 seconds, especially:

• After using the toilet or changing diapers.
• Before eating, preparing, or handling food.
• Before giving yourself or someone else medicine.

It is important to continue washing your hands often even after you feel better. Norovirus can be found in your vomit or feces (poop) even before you start feeling sick. The virus can also stay in your poop for two weeks or more after you feel better and you can still spread norovirus during that time.

Hand sanitizer does not work well against norovirus. You can use hand sanitizers in addition to hand washing, but hand sanitizer is not a substitute for handwashing, which is best.
