The NHS has issued an “important” alert as the prevalence of a grievous illness is “higher than normal”, causing widespread concern. With norovirus cases escalating, the NHS via a post on X warns to watch out for this highly infectious “winter vomiting bug.” The NHS advised: “Cases of norovirus are higher than normal at the moment. Norovirus can spread all year round, causing diarrhoea and vomiting.”
The health service accentuated the need for ample hydration and circulated an infographic specifying vomiting and diarrhoea as key indicators of the virus. Although the symptoms are acutely uncomfortable, they tend to pass after a couple of days. The NHS counselled: “Vomiting and diarrhoea? Stomach bugs, like norovirus, can be very unpleasant but usually go away in around two days. Treating yourself at home is often the best remedy.”
Recent UKHSA data reveals a startling 124.2% hike in reported cases of norovirus from May 26 to June 29 this year (16,679 cases), towering over the five-season average (7,439 cases), reports Gloucestershire Live. The UK Health Security Agency has reported a decline in norovirus cases, with figures dropping back to expected levels after a seasonal high.
The agency revealed: “While norovirus activity has remained high this season, it is now decreasing and returned to expected levels from week 23 onwards.” It elucidated further saying: “Total norovirus laboratory reports during weeks 22 and 26 of 2025 (663 laboratory reports) were 49.1 per cent higher than the five-season average (445 laboratory reports) for the same five-week period, mostly due to high levels of reporting in week 22.”
A dramatic downturn was noted as well: “Overall, norovirus laboratory reports between weeks 22 and 26 were 52.8 per cent lower than during the previous five-week period of weeks 17 and 21 of 2025 (1,405 laboratory reports).” Bearing in mind the symptoms associated with norovirus, the NHS warns that one may experience sudden onset of nausea, vomiting, diarrhoea, accompanied occasionally by a fever, headaches, abdominal cramps, and aching limbs.
The health service offers advice on handling the virus, urging those affected to stay away from educational institutions, workplaces, and healthcare facilities until they’ve been symptom-free for at least 48 hours to help contain the illness. For those unlucky enough to catch the bug, recovery is often rapid, occurring within two or three days provided hydration levels are maintained. The NHS emphasises the importance of fluid intake, stating: “The most important thing is to have lots of fluids to avoid dehydration.”
People frequently contract it if they fail to adequately wash their hands after using the loo. You can become infected by coming into close contact with someone carrying the virus, touching contaminated surfaces or objects and then your mouth, or consuming food prepared by someone who has norovirus.
Contaminated water or food also pose a risk. Besides self-isolating when ill, the NHS outlines several measures to curb the contagion’s spread, recommending that you:
- Wash your hands with soap and water (alcohol hand gels do not kill norovirus) after using the toilet or changing nappies
- Wash your hands with soap and water before preparing, serving or eating food
- Wash clothes and bedding that has faeces or vomit on it at a 60C wash and separately from other laundry
- Clean toilet seats, flush handles, taps and bathroom door handles
- Avoid contact with others as much as possible
If you experience any symptoms:
- Do not go to school, nursery or work until you have not been sick or had diarrhoea for two days
- Do not visit others in hospitals or places like care homes until you have not been sick or had diarrhoea for two days
- If you or your child have diarrhoea for more than seven days or vomiting for more than two days, you should ring 111.
