Norovirus is a highly contagious virus that causes severe stomach pain, vomiting and diarrhea.

It is the most common cause of foodborne-disease outbreaks in the US.

The loss of fluids from vomiting and diarrhea can lead to severe dehydration, especially among more vulnerable people.

Every year in the US:

About 1 out of 15 people contract Norovirus

More than 70,000 people are hospitalized due to Norovirus

Around 600-800 people die from Norovirus


How does it spread?

Norovirus is transmitted when an infected person doesn’t wash their hands properly and comes in contact with others.

The virus is shed in stool and vomit; so if an infected person doesn’t wash their hands after being ill or using the toilet they can easily spread it to other people.

Norovirus can live on surfaces for up to 2 weeks. A person can contract Norovirus by touching a contaminated surface (such as a doorknob or light switch) and then touching their mouth, nose or eyes.

How is it treated?

There is no treatment or vaccine for Norovirus, so prevention is key.

It is important to drink plenty of fluids, including oral rehydration fluids, to prevent dehydration.

Most people with Norovirus get better in 1-3 days

How to prevent Norovirus infection?

Wash your fruits and vegetables thoroughly.

Clean and disinfect contaminated surfaces.

Separate contaminated clothing/linens when washing.
