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.
Latest data reveals that norovirus activity is climbing sharply across the UK at the beginning of 2026. Laboratory reports indicate a 47% rise in the first fortnight of January when compared to late December 2025.
This has resulted in increased outbreaks in hospitals, though overall levels remain within typical seasonal parameters for the time being. Consequently, people are being encouraged to maintain strict hygiene practices.
The UK Health Security Agency (UKHSA) has confirmed a substantial uptick in cases, particularly amongst elderly individuals, alongside a growing number of hospital outbreaks. The surge in norovirus, combined with other winter viruses, is placing considerable pressure on healthcare facilities, reports the Mirror.

What is the ‘stay at home’ alert and the six symptoms?
In a recent update on X, the UKHSA provided guidance for those who have contracted norovirus. It stated: “Diarrhoea and vomiting bugs, like norovirus, are unpleasant for everyone. If you come down with a case, here is what you can do to reduce the spread.”
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.
