Sometimes called the “stomach flu,” norovirus is the most common cause of acute viral gastroenteritis around the world, and the most common cause of foodborne illness in the United States1. Unlike some other infectious diseases, we can get norovirus time and again, and the average person will experience a norovirus infection five times in their life1.
People with norovirus are most contagious when they are sick, and for a few days after they feel better. So, how is it spread? Norovirus spreads quickly and rapidly, people can become infected with it by:
- Eating food or drinking liquids that are contaminated with norovirus, most likely prepared by an individual who is infected with the virus
- Touching surfaces or objects with norovirus on them and then putting your hand or fingers in your mouth
- Having direct contact with a person who is infected with norovirus, for example, when sharing foods, utensils with them2.
- Practice good hand hygiene. Make sure to wash your hands with soap and water at key moments, especially after using the restroom since the virus can spread through stool. Alcohol-based hand sanitizers with at least 60% alcohol, can be used in addition to handwashing.
- Disinfect frequently touched surfaces. Immediately disinfect and clean contaminated surfaces with a disinfectant and cleaner formulated to kill norovirus. For example, PURELL® Surface Sprays are effective against norovirus .
- Wash laundry thoroughly
- Wash fruits and vegetables when preparing food; follow proper food preparation guidelines
- Do not prepare meals when you are sick2
- Whether you think you might have a cold, flu or norovirus, it’s always important to consult a doctor and take precautionary measures to help you and everyone stay healthy.
