Norovirus is primarily transmitted through what means?

Norovirus is primarily transmitted through contaminated water and food. This virus is highly infectious and can easily spread through consumption of food or water that has been contaminated with fecal matter from an infected person. This often occurs when proper hygiene practices are not followed, such as inadequate handwashing after using the restroom or if food handlers do not maintain cleanliness while preparing food.

While undercooked food can be a concern for other pathogens, norovirus is specifically associated with food that has been contaminated after it has been cooked. Direct contact with sick individuals does pose a risk, but the primary routes of transmission for norovirus outbreaks are through contaminated food and water. Insect bites are not associated with the transmission of norovirus at all.
