What to Know About Norovirus: The ‘Winter Vomiting’ Bug Spreading Quickly Across the U.S.
Norovirus, often called the “winter vomiting bug,” is rapidly spreading across the U.S., causing outbreaks in schools, nursing homes, and other close-contact settings. The highly contagious virus leads to sudden vomiting, diarrhea, stomach pain, and dehydration, and can spread through contaminated food, surfaces, or close contact. While most people recover within a few days, prevention such as thorough handwashing, disinfecting surfaces, and staying home when sick is crucial to slowing transmission.
