Does hand sanitizer work well against norovirus? | Fact brief

Hand sanitizer alone does not work well against norovirus, according to the U.S. Centers for Disease Control and Prevention. 

Norovirus, a highly contagious virus that causes vomiting and diarrhea, is the leading cause of foodborne illness in the United States, according to the CDC. It can spread directly from person to person, or through contact with contaminated food, liquids or surfaces. Studies show people can still spread the virus for two weeks or more after their symptoms go away.

To prevent the virus’s spread, the CDC recommends washing hands thoroughly with soap and water after using the bathroom or changing diapers, and before handling food or medication. 

Clean and sanitize kitchen utensils, countertops and other surfaces regularly. Immediately remove and wash clothes or sheets that may have vomit or feces on them. Wear gloves when handling or cleaning potentially contaminated items or surfaces.
