Noroviruses are highly contagious and are shed in the feces of infected humans and animals. Methods of transmission include:
- Eating contaminated food
- Drinking contaminated water
- Touching your hand to your mouth after your hand has been in contact with a contaminated surface or object
- Being in close contact with a person who has a norovirus infection
Noroviruses are difficult to wipe out because they can withstand hot and cold temperatures as well as most disinfectants.
