Cases of the ‘winter vomiting bug’ norovirus are on the rise across the country – with numbers well up on the same period last year. The most recent weekly figures in the Weekly Surveillance Report for Welsh Government show a 118% rise in cases on the previous week.
Although the total number of confirmed cases remains relatively low at 35 these are only cases that are lab tested. Only a small proportion of community cases are confirmed microbiologically.
The increase is a sign of wider community spread and the figures are also significantly higher than last year. In the 12 week period up to October 6 a total of 276 norovirus confirmed cases were reported in Welsh residents. This is an increase of 128.1% in reported cases compared to the same 12 weeks in 2023.

The age groups with the most cases were the 80+ (82 cases) but Public Health Wales said they were also seeing a rise in cases linked to schools and children’s nurseries.
Public Health Wales issued advice on how people can help to reduce cases.
Christopher Williams, Consultant Epidemiologist at Public Health Wales, said: “As we approach the winter months, we have observed a rise in gastrointestinal infections across Wales, including norovirus, commonly known as the ‘winter vomiting bug’. Norovirus infections tend to increase during autumn and winter, impacting schools, nurseries, and care homes. While this trend is expected, we urge everyone to take steps to minimise the spread of the virus, especially through proper hand hygiene.
“We closely monitor laboratory reports of norovirus and outbreaks in the community. Although our most recent data shows a slight decline, we continue to see an overall increase in cases this year, particularly among children in schools and nurseries. This suggests wider community transmission.
“Preventing the spread of norovirus relies on regular and thorough handwashing. We recommend washing hands frequently with soap and warm water, especially after using the toilet and before eating or preparing food.
“Alcohol-based hand sanitisers are not effective against norovirus, so proper handwashing is essential. Additionally, those experiencing symptoms should stay at home for at least 48 hours after symptoms have subsided to prevent further transmission.
“For further advice on protecting yourself and others from gastrointestinal infections, visit the NHS 111 website.”
