Norovirus, more commonly known as the stomach flu, cases are on the rise. As cases increase around the nation, here's what to know about norovirus.

A person sick with norovirus can shed significant amounts of the virus, and it doesn’t take much to infect someone else. Because of this, the virus thrives in crowded, indoor spaces like cruise ships, nursing homes, schools and day care centers, experts said.

Also called the “stomach bug” or “stomach flu,” norovirus tends to surge during the winter months. A national surge of norovirus — the highly contagious illness that can cause vomiting, diarrhea and low-grade fevers — has also sickened some residents across the D.C. region in recent weeks.

If COVID-19 taught us anything it's that washing your hands is often the best thing to do to prevent the spread of infections, including norovirus.

The CDC says norovirus cases are surging. Plus, the FDA issued an alert related to CA shellfish that may be contaminated with the virus.

The CDC has already reported a significant rise in clusters of infections, just two months into norovirus season.

The U.S. Food and Drug Administration is recalling oysters harvested from Puget Sound in December, citing possible norovirus contamination. It’s one of several recalls to impact the Pacific Northwest’s shellfish supply in the past month.
