Health officials are urging the public to take immediate action as a sharp rise in norovirus cases sweeps across England. New data reveals a significant spike in infections during the first weeks of 2026, prompting a renewed focus on essential preventative measures.
Sharp Increase in Cases and Hospital Outbreaks
The UK Health Security Agency (UKHSA) has reported a 47% surge in confirmed norovirus cases in the first two weeks of January 2026. The data indicates that the virus is currently most prevalent among people aged 65 and over. While overall activity remains within expected seasonal parameters, authorities have noted a concerning uptick in outbreaks within hospital settings.
Amy Douglas, Lead Epidemiologist at the UKHSA, stated: "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 emphasised that while this is within expected levels, public action is crucial to prevent further escalation.
Critical Hygiene Measures to Curb the Spread
In response to the surge, the UKHSA is reminding everyone of the simple but effective steps needed to limit transmission. A key point of guidance is that alcohol-based hand gels are ineffective against norovirus. Instead, frequent handwashing with soap and warm water is essential.
For cleaning contaminated surfaces, the agency recommends using bleach-based products. Proper ventilation in indoor spaces can also help reduce the spread of other seasonal respiratory illnesses, such as flu, whose levels have declined in the same period alongside COVID-19 and RSV.
Public Advice: Stay Home if Unwell
The core message from health experts is clear: if you experience symptoms, you must stay at home to protect others. The specific guidance includes:
- Do not return to work, school, or nursery until 48 hours after symptoms of diarrhoea and vomiting have completely stopped.
- Avoid preparing food for others during this period.
- If you need to go out while symptomatic, consider wearing a face covering, especially around vulnerable individuals.
- Avoid visiting hospitals and care homes to prevent passing the infection to those most at risk.
"Washing your hands with soap and warm water and using bleach-based products to clean surfaces will also help stop infections from spreading," reiterated Amy Douglas. The UKHSA stresses that these straightforward actions are vital for controlling the unpredictable trends of winter viruses and maintaining the current downward trajectory seen in other respiratory infections.
