A fast-moving wave of norovirus — the highly contagious “winter vomiting bug” — is spreading through the country earlier than expected. Wastewater readings in the Northeast and Midwest are among the highest seen in years, and doctors say cases have been rising steadily since mid-October. The virus spreads easily through contaminated hands, surfaces and food, and symptoms usually strike suddenly with vomiting and diarrhea.
Although the illness typically lasts only two to three days, people remain contagious for several days after they start feeling better. That means someone who seems recovered can still spread the virus while preparing food or attending gatherings. With holiday travel and indoor celebrations underway, experts warn this early surge could become especially disruptive for families.
There is no treatment for norovirus — it has to run its course — so prevention is key. Unlike many germs, norovirus is not killed by alcohol-based hand sanitizer. Washing hands with soap and water is essential. Avoiding food prep while recovering, cleaning high-touch surfaces and staying home when sick can help slow the spread during one of the busiest social months of the year.
