People have been issued an urgent health warning regarding a nasty bug currently spreading across the UK. Those experiencing symptoms of the illness are being advised to remain at home and adhere to a 48-hour rule.
They are also being urged to avoid busy areas, including schools, workplaces, and hospitals. The bug, which the UK Health Security Agency (UKHSA) describes as “unpleasant for everyone”, is currently responsible for a surge in cases this month.
An urgent health alert has been issued as a troublesome virus sweeps across the UK. Authorities are advising individuals who exhibit symptoms to stay home and follow a 48-hour isolation protocol.
Officials are also recommending people steer clear of crowded places like schools, offices, and hospitals. The virus, described by the UK Health Security Agency (UKHSA) as “unpleasant for all ages,” has led to a noticeable spike in cases this month.
Recent statistics indicate a sharp increase in norovirus cases at the beginning of 2026. Laboratory reports have shown a 47% rise in the first two weeks of January compared to the end of December 2025.
This rise has led to more outbreaks in hospitals, although the overall situation remains within expected seasonal limits for now. The public is urged to follow strict hygiene measures to curb the spread.
The UK Health Security Agency (UKHSA) has verified a significant rise in cases, especially among older populations, and a growing number of hospital outbreaks. This surge, along with other winter viruses, is exerting heavy pressure on healthcare services, as reported by the Mirror.

The health body cautions that the diarrhoea and vomiting bug spreads rapidly, urging anyone affected to take straightforward precautions to prevent transmission.
It highlights six key symptoms to watch for, including nausea, diarrhoea, vomiting, elevated temperature, headache and aching limbs.
Providing additional advice, the UKHSA stated: “Stay at home for 48 hours after your symptoms clear.”
It also suggests regular handwashing with soap and warm water. To minimise the risk of spreading the infection within your household, any contaminated bedding and clothing should be laundered at 60 degrees.
Regarding what to avoid, the UKHSA emphasises staying away from workplaces, care homes, schools and hospitals. It also advises against cooking for others.
NHS advice to follow:
- stay at home and get plenty of rest
- drink lots of fluids, such as water or squash – take small sips if you feel sick
- carry on breast or bottle feeding your baby – if they’re being sick, try giving small feeds more often than usual
- give babies on formula or solid foods small sips of water between feeds
- eat when you feel able to – it may help to avoid foods that are fatty or spicy
- take paracetamol if you’re in discomfort – check the leaflet before giving it to your child

What does the NHS say?
The NHS states: “Diarrhoea and vomiting are common in adults, children and babies. They’re often caused by a stomach bug and should stop in a few days. The advice is the same if you have diarrhoea and vomiting together or separately… Diarrhoea and vomiting can usually be treated at home. The most important thing is to have lots of fluids to avoid dehydration.”
In both adults and children, diarrhoea typically resolves within five to seven days, whilst vomiting generally subsides within one to two days. The NHS also advises remaining off school or work until you’ve been free from sickness or diarrhoea for at least 48 hours.
“If you have a high temperature or do not feel well enough to do your normal activities, try to stay at home and avoid contact with other people until you feel better,” it advises.
