The UK Health Security Agency (UKHSA) has issued a stark warning as cases of the highly contagious norovirus have rocketed across the country, leading to a significant strain on NHS hospitals.
Sharp Rise in Cases and Hospitalisations
Official statistics reveal a dramatic 47 per cent increase in norovirus reports during the first two weeks of 2026, compared to the previous fortnight ending on 28 December.
This surge has translated directly into hospital pressure. NHS data shows that in the week leading up to 11 January, an average of 567 hospital beds were occupied each day by patients suffering from symptoms of the virus, which causes intense vomiting and diarrhoea.
Vulnerable Groups at Risk
While most healthy individuals recover fully within two to three days, the virus poses a serious risk of dehydration for the very young, the elderly, and people with weakened immune systems.
Amy Douglas, Lead Epidemiologist at the UKHSA, highlighted the concerning trend: “We have seen a notable increase in norovirus cases in recent weeks among those aged 65 years and over, with more hospital outbreaks also being reported.”
She stressed that while current levels are within seasonal expectations, public action is crucial to prevent further escalation.
Five Essential Tips to Halt the Spread
Health authorities are urging the public to follow these key hygiene measures to protect themselves and others, particularly the most vulnerable:
- Wash hands thoroughly with soap and warm water: Alcohol-based hand gels are not effective against norovirus.
- Use bleach-based products for cleaning surfaces: This is vital to kill the virus on contaminated counters, handles, and bathrooms.
- Stay home if you have symptoms: Do not return to work, school, or nursery until 48 hours after symptoms have completely stopped. Avoid preparing food for others during this time.
- Keep your home well-ventilated: Fresh air can help reduce the concentration of viral particles indoors.
- Protect healthcare settings: If you are unwell, avoid visiting hospitals and care homes to prevent passing the infection to vulnerable residents.
Douglas emphasised the simple steps that make a difference: “Washing your hands with soap and warm water and using bleach-based products to clean surfaces will also help stop infections from spreading.”
The public is advised to remain vigilant, as norovirus is notoriously unpredictable and can spread rapidly in communities and closed settings.
