Transmission
You can get norovirus infection by
- Eating food or drinking liquids contaminated by a food handler infected with the virus
- Touching surfaces or objects contaminated with a norovirus, and then putting your hands in your mouth
- Having direct contact with someone infected with a norovirus, such as caring for or sharing food or eating utensils with someone sick with norovirus
- Eating improperly cooked contaminated shellfish, especially oysters
- Eating improperly prepared uncooked fruits and vegetables
- Drinking contaminated water
Noroviruses are found in the stool or vomit of people who are infected. If you have been infected with a norovirus, you can continue to transmit it to others even when you no longer have symptoms.
