Have you ever wondered if it’s possible to catch norovirus more than once? Norovirus, often referred to as the stomach flu, is a highly contagious virus that causes vomiting and diarrhea. In this article, we’ll explore whether or not you can catch norovirus twice and what you need to know to protect yourself and your loved ones.

Understanding Norovirus

Norovirus is a common virus that can affect people of all ages. It spreads easily through contaminated food or water, as well as through close contact with an infected person. Symptoms of norovirus typically include nausea, vomiting, diarrhea, and stomach cramps. The virus is most commonly spread in crowded places such as schools, cruise ships, and nursing homes.

Can You Catch Norovirus Twice?

While it is possible to catch norovirus more than once, it is not common. Most people develop immunity to the virus after being infected once. However, there are many different strains of norovirus, so it is still possible to be infected with a different strain in the future. This is why outbreaks of norovirus can occur in places where people are in close quarters, such as schools or cruise ships.

Protecting Yourself from Norovirus

There are several steps you can take to protect yourself from norovirus. First and foremost, practice good hygiene by washing your hands frequently with soap and water. Avoid sharing food or drinks with others, and disinfect surfaces that may be contaminated with the virus. If you or someone in your household is sick with norovirus, be sure to clean and disinfect all surfaces to prevent the spread of the virus.

Seeking Medical Attention

If you believe you have been infected with norovirus, it is important to seek medical attention. While most cases of norovirus are mild and resolve on their own, severe dehydration can occur in some cases. Symptoms of dehydration include dizziness, dry mouth, and decreased urine output. If you experience any of these symptoms, contact your healthcare provider immediately.


In conclusion, while it is possible to catch norovirus more than once, it is not common. By practicing good hygiene and taking steps to protect yourself from the virus, you can greatly reduce your risk of infection. If you do become infected with norovirus, seek medical attention if necessary and take steps to prevent the spread of the virus to others. Stay informed and stay healthy!
