Norovirus cases remain high while respiratory viruses fall - GOV.UK
Weekly UKHSA report for the 2025/26 season, monitoring respiratory viruses.
www.gov.ukHere are the latest reliable signals on norovirus as of now.
-
U.S. outbreaks and wastewater signals: Norovirus activity remains elevated in parts of the U.S., with wastewater data showing higher-than-average levels in recent weeks and clusters linked to schools and cruise ships. This aligns with ongoing seasonal patterns and the emergence of highly contagious strains, though state-by-state outbreak counts can vary.[1][2][4]
-
Global and domestic context: In several regions, health agencies note that norovirus activity is higher than typical for the season, while the overall number of outbreaks may still be lower than the peak levels seen in previous years. Public health authorities continue to monitor variants and transmission routes.[3][4]
-
Practical guidance: There is no licensed vaccine for norovirus yet, though vaccine candidates are under development. Preventive tips include rigorous hand hygiene, surface disinfection with effective EPA-registered products, staying hydrated if symptoms occur, and seeking medical care if dehydration or severe symptoms develop.[6][1]
-
What to watch next: Public health agencies (CDC, UKHSA, etc.) are tracking outbreak dynamics, seasonality, and potential new variants through laboratory testing and wastewater surveillance to anticipate peaks and tailor guidance for settings like schools, cruise ships, and healthcare facilities.[4][1]
Illustration of what this means for Prague/ CZ:
- Norovirus risk is generally higher in crowded settings and travel-related contexts. In Prague, you might see local advisories if cases rise, especially in schools, restaurants, or cruise-related visitors; standard hygiene precautions remain important.[1]
If you’d like, I can tailor a quick one-page briefing with:
- A current quick-read chart of outbreak signals by region (US/Europe)
- Key prevention steps you can implement at home or in a business
- A short list of symptoms and when to seek care
Would you prefer a regional focus (Czech Republic/Europe) or a general US-global snapshot? I can also pull recent CDC and UKHSA guidance in a concise checklist.[4][6]
