Norovirus: Sharp rise in vomiting in winter – what to do if you become infected | UK | News

The rotting disease, which causes severe bouts of diarrhea and nausea, is on the rise after the number of reported cases rose by almost a third in two weeks.

The UK Health Security Agency (UKHSA) urged those infected with norovirus to stay at home and avoid preparing food for others after revealing a 31.7% rise in infections between November 4 and 17 compared with the previous two weeks.

There were 562 reported cases between November 4 and 17, up from 427 two weeks earlier.

It also said the number of reports was almost double the five-season average (comparing this year’s data with previous years excluding the Covid period) of 283.

Although norovirus cases typically increase in winter, the UKHSA said: “The increase in reports started earlier this season compared to the five seasons on which the average is calculated.”

It said incidence is “rising again across all age groups, with the largest increases occurring among adults, especially among adults aged 65 years and older.”

And the situation may be worse than government data shows: the UKHSA estimates that for every reported case of norovirus, there are around 288 in the community it is unaware of.

Amy Douglas, UKHSA epidemiologist, said: “We continue to see high levels of norovirus circulating in our communities.”

Norovirus is a stomach illness that causes diarrhea and nausea. Also known as winter vomiting, the NHS describes it as “very unpleasant”.

People usually become infected with it through close contact with someone who has norovirus.

They can also become infected by eating food prepared or processed by someone who is sick, or by touching their mouth after touching surfaces or objects that have the virus on them.

In addition to feeling unwell and bouts of diarrhea, those infected may experience high fever, headache, and pain in the arms and legs.

Symptoms usually appear a day or two after infection.

Ms Douglas said those who have contracted the virus can “take steps to avoid passing on the infection”.

She said: “If you have diarrhea or vomiting, do not return to work, school or daycare until 48 hours have passed after your symptoms have stopped, and do not prepare food for others during this time.

“If you feel unwell, avoid visiting people in hospitals and care homes to prevent transmission in these settings.

“Washing your hands with soap and warm water and using bleach-based products to clean surfaces will also help stop the spread of infections.

“Alcohol gels do not kill norovirus, so don’t rely on them alone.”

The NHS recommends that those who have norovirus get plenty of rest and drink plenty of water to stay hydrated.

“You will usually start to feel better within two to three days,” it says.
