The National Center for Immunization and Respiratory Diseases recently reported data indicating cases of norovirus are spiking in the United States.

Norovirus is a very contagious virus that causes vomiting and diarrhea.

As of March 15, 2023, the 3-week moving average is reaching a new peak since the norovirus outbreak began in August 2022.

Each of the four regions has displayed similar trends, with the Northeast registering the steepest uptick.

In the U.S., cases of norovirus occur most frequently during late fall, winter, and early spring. 

According to the U.S. Centers for Disease Control and Prevention (CDC), people can get norovirus illness many times in their life because there are many different types of noroviruses.

Infection with one type of norovirus may not protect you against other types.

The CDC says it is possible to develop immunity to specific types. But, it is not known exactly how long immunity lasts.

This may explain why so many people of all ages get infected during norovirus outbreaks. About 80% of children will experience a norovirus infection within one year of birth.

As of March 21, 2023, there are no approved norovirus vaccines in the U.S., Europe, or the U.K.
