The UK Health Security Agency (UKHSA) has issued an urgent 'stay at home' alert as norovirus cases surge across the country. The agency warns that individuals experiencing six specific symptoms should avoid leaving their homes until at least 48 hours after symptoms have ceased.
According to the latest UKHSA data, norovirus cases in the two-week period ending January 25, 2026, were 73.8% higher than the five-season average for that period, and 18.3% higher than the previous two-week period. The most affected groups are those aged 65 and over, and children under five. The dominant strain currently circulating is GII.4.
The main symptoms of norovirus include nausea, vomiting, and diarrhoea. Additional symptoms may include headaches, aching arms and legs, and a high temperature. The UKHSA advises that infected individuals should not return to work, school, or nursery until 48 hours after symptoms stop, and should avoid preparing food for others during that time.
To reduce spread, the UKHSA recommends washing hands with soap and warm water, as alcohol gels are ineffective against norovirus. Soiled clothing and bedding should be washed at 60°C, and surfaces such as toilet seats, flush handles, and door handles should be cleaned daily. Infected individuals should also avoid visiting hospitals and care homes.
Lead Epidemiologist Amy Douglas stated: 'We have seen a notable increase in norovirus cases in recent weeks among those aged 65 years and over. Washing your hands with soap and warm water and using bleach-based products to clean surfaces will help stop infections from spreading.'
