Winter Stomach Bug Surge: Norovirus Spreads Fast

Norovirus, a prevalent cause of vomiting and diarrhea in the U.S., is currently seeing an increase in cases across many states. This highly contagious stomach bug, typically peaking from November to April, is experiencing a surge due to a new strain.

Its transmission differs from respiratory viruses; norovirus spreads through the fecal-oral route, often via contaminated hands, surfaces, food, or airborne particles. It can persist on surfaces for extended periods, posing risks in crowded settings like daycares and cruise ships. Contaminated food and shellfish also present a risk.

Effective prevention centers on rigorous hand washing with soap and water, as hand sanitizers are less effective. Disinfecting surfaces with bleach-based cleaners and washing linens are also recommended. Staying home when sick and monitoring for dehydration are vital steps to manage infection.
