Norovirus Outbreaks - CDC
Learn about current norovirus outbreaks and alerts and common settings where outbreaks occur.
www.cdc.govNorovirus spreads mainly through the “fecal-oral” route, and outbreaks tend to spread quickly in places with close contact (households, schools, nursing homes, cruise ships).
Latest reports (what’s being said now)
Recent coverage says norovirus activity has been rising/remaining high in parts of the US seasonally, with reports pointing to new or changing viral variants and the fact that outbreaks can start earlier than usual. In the US, reporting has also cited wastewater monitoring as showing elevated norovirus levels and increased spread signals in some regions.[1][2]
How norovirus spreads (common routes)
- Direct person-to-person contact: especially when caregivers or household members touch an infected person’s vomit/diarrhea and then touch their own mouth.[2]
- Contaminated surfaces → hands → mouth: the virus can persist on surfaces, and people can get infected after touching “high-touch” areas and then eating or touching their face.[7][2]
- Contaminated food or water: infection can occur after handling or consuming contaminated items (often linked to poor hygiene after toilet use or during food preparation).[2][7]
- Small-particle spread during vomiting: outbreaks can accelerate when vomit aerosolizes particles that others then inhale or contact with hands/mouth.[2]
- Crowded indoor settings: cruise ships and similar close-quarters environments are repeatedly mentioned as settings where outbreaks can spread fast.[7][2]
What to do if it’s “going around”
- Wash hands with soap and water, especially after using the bathroom and before eating (more reliable than sanitizer alone for norovirus).[2]
- Isolate as able (stay home from work/school while sick; avoid preparing food for others).[7]
- Disinfect correctly surfaces in shared bathrooms/kitchens, focusing on vomit/diarrhea cleanup areas.[7]
If you tell me your country/state (you’re in Dallas, Texas—do you want US-specific updates for Texas/nearby?), I can narrow this to the most relevant recent outbreak tracking and guidance.
