What is the source of norovirus?

Answer 1

Norovirus can be acquired through food, water, or physical contact with infected people or surfaces. It is often transmitted by eating shellfish since they accumulate norovirus in their bodies. The infectious dose of norovirus is very low, which is why it is spread so easily in places where people are in close contact (schools, cruise ships, military barracks, nursing homes, parties, etc...). A typical infection usually lasts 24-48 hours, but infected people continue to shed virus in their feces for up to several weeks, allowing them to continue to transmit the virus to people they contact if good hygiene is not maintained.
