Health officials in England have issued a stark warning for people to remain at home if they are unwell, following a significant and rapid increase in cases of norovirus across the country.
Sharp Rise in Infections Among Elderly
Data released by the UK Health Security Agency (UKHSA) reveals a concerning trend in the first two weeks of January 2026. Reported cases of the highly contagious stomach bug have surged by approximately 47 per cent compared to expected levels. The rise has been particularly pronounced among those aged 65 and over, with a notable increase in outbreaks within hospital settings.
Amy Douglas, the lead epidemiologist at the UKHSA, commented on the situation. "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 stated. While the current figures remain within anticipated parameters for the season, the agency is urging vigilance to prevent further escalation.
Critical Steps to Curb the Spread
The UKHSA is emphasising that simple but effective hygiene measures can make a substantial difference. The core advice is clear: anyone experiencing diarrhoea and vomiting must stay away from work, school, or nursery. This isolation should continue for at least 48 hours after all symptoms have completely stopped.
During this period, individuals should also avoid preparing food for others. Furthermore, to protect the most vulnerable, people who are unwell are strongly advised against visiting hospitals and care homes to prevent passing the infection on to residents and patients.
Respiratory Virus Update and Vaccination Call
In a separate but related health update, Dr Alex Allen, a consultant epidemiologist at UKHSA, provided a mixed picture on other seasonal viruses. "It's encouraging to see that levels of flu and RSV have fallen for another week," Dr Allen noted. However, he cautioned against complacency, citing historical data that suggests the flu season could persist for several more months.
"Respiratory viruses are unpredictable, but there are steps people can take to reduce the spread," he added, highlighting the ongoing importance of vaccination. Appointments for the seasonal flu vaccine remain available through the NHS national booking system, and those at highest risk who have not yet been vaccinated are urged to do so promptly.
The RSV vaccination programme also continues year-round for pregnant women and any older adults aged between 75 and 80 years old who have not yet received a dose. Health officials stress that these vaccinations are a key tool in maintaining the downward trend for respiratory illnesses and ensuring protection for the remainder of the winter season.
