What is the outlook for people with norovirus?

Most people with norovirus feel better after 2 or 3 days, with no long-term effects. Because norovirus includes many different types of viruses, you can get the illness more than once. Some people get it several times throughout their lifetime.

How long does norovirus stay in my system?

Norovirus can be present in your stool both before symptoms start and for 2 weeks after the symptoms stop.
