Practice proper hand hygiene
Wash your hands carefully with soap and water, especially after using the toilet and changing diapers and always before eating or preparing food. If soap and water aren’t available, use an alcohol-based hand sanitizer. These alcohol-based products can help reduce the number of germs on your hands, but they are not a substitute for washing with soap and water.
Take care in the kitchen
Carefully rinse fruits and vegetables, and cook oysters and other shellfish thoroughly before eating.
Do not prepare food while infected
People with norovirus illness should not prepare food for others while they have symptoms and for at least 2 days after they recover from their illness.
Clean and disinfect contaminated surfaces
After throwing up or having diarrhea, immediately clean and disinfect contaminated surfaces using a bleach-based household cleaner as directed on the product label. If no such cleaning product is available, you can use a solution made with 5 tablespoons to 1.5 cups of household bleach per 1 gallon of water.
Wash laundry thoroughly
Immediately remove and wash clothing or linens that may be contaminated with vomit or stool. Handle soiled items carefully—try not to shake them —to avoid spreading virus. If available, wear rubber or disposable gloves while handling soiled clothing or linens and wash your hands after handling. Wash soiled items with detergent at the maximum available cycle length and then machine dry.
