The UK Health Security Agency (UKHSA) has issued a warning about a potential second wave of norovirus infections in the UK, highlighting the emergence of new genotypes that could affect those previously infected this winter.
This development is particularly concerning for healthcare settings like hospitals and care homes.
Understanding the Norovirus Threat
The UKHSA’s recent alert underscores the evolving nature of norovirus strains, with genotypes GII.17 and GII.4 now circulating more widely.
This shift means that individuals who have already contracted norovirus may not be immune to these new strains, increasing the risk of reinfection.
The situation is especially critical in environments such as hospitals and care homes, where vulnerable populations are at higher risk.
Impact on Healthcare Settings
Norovirus outbreaks pose significant challenges for healthcare facilities, particularly those catering to older adults and immunocompromised individuals.
The virus’s high transmissibility can lead to rapid spread within these settings, straining resources and necessitating stringent infection control measures.
Amy Douglas, Lead Epidemiologist at UKHSA, emphasized the severity of symptoms in these groups and urged people with symptoms to avoid visiting such facilities.
She said:
“Norovirus levels are still exceptionally high and now with multiple genotypes spreading at the same time, people could end up getting infected more than once this season.
We are seeing the biggest impacts in health and social care settings, such as hospitals and care homes. Symptoms of norovirus can be more severe in older adults, young children and those who are immunocompromised. If you have diarrhoea and vomiting, please do not visit hospitals and care homes or return to work, school or nursery until 48 hours after your symptoms have stopped. And don’t prepare food for others, as you can still pass on the virus during this time.
Alcohol gels do not kill norovirus. Wash your hands with soapy warm water and clean surfaces with bleach-based products where possible to help stop infections from spreading.”
Prevention Strategies for Individuals
To mitigate the spread of norovirus, individuals are advised to practice good hygiene by washing hands with soap and water rather than relying on alcohol-based sanitizers, which are ineffective against the virus.
Additionally, those experiencing symptoms should refrain from preparing food for others and avoid public places until 48 hours after symptoms subside.
Practical Tips for Reducing Spread
- Avoid visiting hospitals or care homes if symptomatic
- Wash hands thoroughly with soap and water
- Use bleach-based products for cleaning surfaces
- Stay home from work or school if experiencing symptoms
- Avoid preparing food for others while symptomatic
| Description | Details |
|---|---|
| Increase in Cases | 29.4% higher than previous fortnight; double 5-season average |
| GII.17 Prevalence | Dropped from 76% to 59% since November |
| GII.4 Prevalence | Increased from 10% to 29% over three months |
The Broader Implications of Norovirus Outbreaks
The current surge in norovirus cases highlights broader implications beyond immediate health concerns. Businesses in sectors like healthcare and food service must remain vigilant to prevent outbreaks that could disrupt operations and impact economic stability.
Understanding these risks allows organizations to implement effective strategies that protect both employees and customers.

Something to Ponder
This ongoing situation serves as a reminder of the dynamic nature of viral infections like norovirus.
As new genotypes emerge, maintaining vigilance through personal hygiene practices remains crucial in mitigating further spread within communities and protecting vulnerable populations.
