The UK Health Security Agency (UKHSA) has issued a 'stay at home' warning for people experiencing six key symptoms of norovirus. The advisory, published on February 3, urges individuals to refrain from leaving home while unwell and to remain indoors for 48 hours after symptoms resolve.
Recent data shows norovirus cases are rising across the UK, with laboratory reports for the fortnight ending January 25, 2026, 73.8% above the five-season average and 18.3% higher than the previous two-week period. The highest infection rates are among those aged 65 and over and children under five, with the GII.4 strain now predominant.
The three main symptoms are vomiting, nausea, and diarrhoea. Sufferers may also develop a high temperature, headaches, and aching arms and legs. The UKHSA advises staying away from workplaces, schools, hospitals, and care homes, and not preparing food for others until 48 hours after symptoms stop.
To reduce spread, the UKHSA recommends washing hands with soap and warm water, washing contaminated clothing and bedding at 60°C, and cleaning toilet seats, flush handles, taps, surfaces, and door handles daily. Alcohol gels are ineffective against norovirus.
Lead Epidemiologist Amy Douglas said: '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.'
The NHS advises drinking plenty of fluids to avoid dehydration, and avoiding fruit juice or fizzy drinks. Diarrhoea typically subsides within five to seven days, vomiting within one to two days. Those affected should not share towels, flannels, cutlery, or utensils, and avoid swimming pools for 48 hours after symptoms end.
