THE number of people sick with norovirus is more than double what’s typically expected for this time of year.
At least 503 people tested positive for the “extremely contagious” winter vomiting bug in September, UK Health Security Agency (UKHSA) figures show.

That’s a 133 per cent jump from the five-season average of 216.
Experts have warned that infection rates are “likely” to continue rising in the coming weeks as children return to classrooms across the country.
Adults and children who might have the bug are being urged to stay home from work and school.
Norovirus – also known as the “winter vomiting bug” – is a highly infectious viral illness.
The report, based on laboratory test results, suggests that the rise in detected cases may be linked to changes in disease surveillance methods following the pandemic.
Changes to testing and reporting to national surveillance, and the weather getting colder are also considered possible factors in the report.
Not all norovirus cases are reported or tested, so the actual number of infections is likely to be much higher.
Most cases are being recorded in the over-65s, though the virus, which triggers sickness and diarrhoea, continues to affect all age groups.
Amy Douglas, epidemiologist at UKHSA said: “Since April, norovirus levels have remained higher than expected and with kids returning to school over the last few weeks, cases are likely to rise.”
Parents already facing backlash from the rise in cases have taken to X (formerly Twitter) to express their concerns.
Kathryn (@kadamssl) shared, “Kids are literally throwing up in the hallway of my daughter’s school.”
Faye Ameredes (@FAmeredes) added, “My grandson’s school has closed due to norovirus. Yuk! Don’t know how many days this will last.
There have been 753 lab reports so far this year, compared to a five-season average of 476.
‘Alcohol gels do not kill norovirus’
Amy urged anyone with diarrhoea and vomiting to take vital steps to avoid passing it on.
She said: “Do not return to work, school or nursery until 48 hours after your symptoms have stopped and don’t prepare food for others in that time either.
“If you are unwell, avoid visiting people in hospitals and care homes to prevent passing on the infection in these settings.
When to call 111 and 999 for norovirus
NOROVIRUS usually goes away on its own after a couple of days and doesn’t require medical attention.
But you might need to speak to a doctor if:
- You’re worried about your baby who is younger than 12 months
- Your child stops breast or bottle feeding while they’re ill
- You think your child under five might be dehydrated – signs could include fewer wet nappies
- You’ve used rehydration sachets but still have signs of dehydration
- You or your child keep being sick and can’t keep fluids down
- You or your child have bloody diarrhoea or start bleeding from the bottom
- You or your child have diarrhoea for more than seven days or are vomiting for more than two days
And if you spot any of the following signs, it’s vital to seek urgent care:
- Vomit in your blood
- Vomit that looks like ground coffee
- Green vomit (adults) or yellow-green vomit (children)
- A stiff neck
- Pain when looking at bright lights
- A sudden, severe headache or stomach ache

“Washing your hands with soap and warm water and using bleach-based products to clean surfaces will also help stop infections from spreading.”
She added: “Alcohol gels do not kill norovirus so don’t rely on these alone.”
Norovirus is a highly contagious stomach bug that causes vomiting (often projectile) and diarrhoea.
It is commonly accompanied by aching arms and legs, a high temperature, abdominal pain, and a headache, according to the NHS.
The bug spreads easily through contact with someone who has the virus or with contaminated surfaces or foods.
This makes nurseries, schools, workplaces, hospitals, care homes, cruise ships, and family homes over the colder months perfect breeding grounds.
While most people make a full recovery within a few days, norovirus can lead to dehydration, especially among the very young, the elderly or those with weakened immune systems.
