How can noroviruses spread?

ANSWER

Noroviruses thrive in close quarters, such as restaurants, day-care centers, and nursing homes, because they are hardy and highly contagious. They can survive temperature extremes in water and on surfaces.

Once someone is infected from contaminated food, the virus can quickly pass from person to person through shared food or utensils, by shaking hands, or through other close contact.

When someone with the virus vomits, the virus can spread through the air and contaminate surfaces. The virus also spreads through feces, meaning that someone who doesn’t thoroughly wash his hands after using the bathroom can pass it along. Dirty diapers can also harbor norovirus.
