The UK Health Security Agency (UKHSA) has reminded the public of a crucial 48-hour rule amid persistently high norovirus cases. Health experts urge individuals experiencing symptoms of the winter vomiting bug to stay home for two days after symptoms subside.
According to the latest UKHSA update, norovirus cases “remain high,” particularly among those aged 65 and over. Data from February 16 to March 1 shows cases are 30.5% higher than the five-season average, though overall infections have begun to decrease.
Amy Douglas, lead epidemiologist at UKHSA, emphasised the importance of hygiene and isolation. “Wash your hands with soap and warm water and use bleach-based products to clean surfaces,” she said. “Alcohol gels do not kill norovirus so don’t rely on these alone.”
Douglas stressed the 48-hour rule: “If you have diarrhoea and vomiting, don’t return to work, school or nursery until 48 hours after your symptoms have stopped and don’t prepare food for others in that time either.” She also advised avoiding visits to hospitals and care homes to protect vulnerable individuals.
The NHS echoes this advice, stating on its website: “Do not go to school, nursery or work until you have not been sick or had diarrhoea for two days.” Symptoms of norovirus include sudden nausea, vomiting, diarrhoea, high temperature, headaches, stomach cramps, and body aches. If diarrhoea persists beyond seven days or vomiting beyond two days, the NHS advises calling 111.
