The UK Health Security Agency (UKHSA) has issued a strong public warning about norovirus, urging anyone affected to remain at home for 48 hours after symptoms cease, as individuals can still be infectious. Known as the ‘winter vomiting bug’, norovirus causes vomiting, diarrhoea, and severe discomfort. While typically seasonal, England has seen an alarming spike in cases, with 14,959 reported between 31 March and 27 April - more than double the five-year average. Hospital outbreaks are also up 43.3% above historical norms. Though recent weeks show a slight decline, infection levels remain significantly high. Norovirus spreads easily via contaminated food, surfaces, or close contact, and can be transmitted even before symptoms begin. The UKHSA stresses the importance of staying home, avoiding hospitals or GP visits while symptomatic, and refraining from cooking for others until 48 hours after recovery. Parents are advised not to send children to school during this period, and all should practice vigilant hygiene to prevent spread.
