Is norovirus contagious?

Page last updated 07 July 2020

Yes, norovirus is very contagious. If you get norovirus, you can shed billions of virus particles in your faeces or vomit. It only takes a few viral particles to make others sick. A person with norovirus is most contagious when they have symptoms and for a few days after they have recovered.
