Norovirus, a highly contagious virus causing vomiting and diarrhea, is spreading rapidly across the United States, with cases rising sharply in December. The CDC reported 91 outbreaks in one week, up from 69 the previous week. Symptoms, including nausea, stomach pain, and diarrhea, appear 12-48 hours after exposure and typically last 1-3 days. The virus spreads through contaminated food, surfaces, and close contact with infected individuals.
To prevent infection, doctors recommend thorough handwashing with soap and water, as alcohol-based sanitizers are less effective. Disinfect contaminated surfaces with bleach-based cleaners and ensure food is handled safely—rinse produce and cook seafood thoroughly. Infected individuals should isolate and avoid preparing food for at least two days after symptoms subside.
There is no specific treatment for norovirus, so staying hydrated is crucial. Those with severe symptoms, especially children and the elderly, should seek medical attention. With its high transmissibility and resilience, health experts emphasize vigilance to curb the ongoing outbreaks.
