Overview

• UKHSA urged people on X to remain at home for 48 hours after vomiting or diarrhoea stop because they can still spread norovirus.
• NHS says key symptoms appear suddenly and include nausea, vomiting and diarrhoea, with possible fever, headache, stomach pain and body aches.
• Transmission occurs via the faecal–oral route through close contact, contaminated surfaces, food or water, and handwashing with soap and water is advised over alcohol gels.
• Young children, older adults and people with weakened immune systems face higher risk of severe illness, though most cases improve within about two days with rest and fluids at home.
• WHO estimates about 685 million cases and 200,000 deaths globally each year, while recent UK data show July activity was low after higher levels earlier in the year.
