Norovirus is spreading earlier again this year, wastewater data shows
Last year's outbreaks were the largest in a decade, fueled by an emerging variant of the highly contagious, hard-to-kill virus. What will this year look like?
www.nbcnews.comNorovirus spreads extremely easily, mainly through the “fecal-oral” route—tiny amounts of virus from vomit or stool get onto hands, surfaces, or food, and then are swallowed.[2]
How it’s spreading (the main routes)
- Direct contact: touching an infected person (especially during vomiting/diarrhea episodes) can transfer virus to your hands, then to your mouth.[2]
- Contaminated surfaces: the virus can persist on high-touch areas (bathrooms, doorknobs, countertops), so touching them and then touching your mouth can cause infection.[2]
- Contaminated food/water: infection can occur when food or drinks are contaminated by an infected handler or by contaminated water.[2]
- Close quarters in winter: outbreaks tend to spread faster in indoor settings (schools, cruise ships, households) because people are in close contact and share spaces.[2]
“Latest news” theme you may be seeing
Recent reporting highlights wider and earlier seasonal activity, with some coverage attributing the surge pattern to highly contagious norovirus variants and the way outbreaks propagate through communities.[1][2]
What you can do to reduce risk
- Handwashing with soap and water after using the bathroom and before eating (hand sanitizer may be less reliable for norovirus than soap-and-water cleaning).[2]
- Disinfect vomit/stool-contaminated areas promptly and keep contaminated items away from others.[2]
- Avoid preparing food for others while sick and for long enough after symptoms resolve (public health guidance typically emphasizes staying home during active symptoms and for a period afterward).[2]
