- Norovirus cases in UK are 75% above average
- Outbreaks mainly in care facilities, affecting elderly
- Experts link surge to cold weather, post-COVID immunity drop
Norovirus cases in the United Kingdom are 75% higher than the average as a result of an outbreak in care facilities.
According to the UK Health and Security Agency (UKHSA), over 1,200 cases of the virus were detected in April, compared to the five-season average of 706 lab-confirmed cases.
The majority of laboratory cases were discovered in individuals over the age of 65 and throughout the social care and care facility sectors.
The winter vomiting bug, norovirus, is a stomach disease that induces diarrhea and vomiting.
The UKHSA has indicated that the disproportionately high number of cases may be attributable to the unseasonably frigid weather or modifications in epidemiology or testing procedures that followed the pandemic, as reported by The Times.
In May, it was reported that the number of cases had reached its greatest seasonal level in five years due to a nationwide surge.
Amy Douglas, a norovirus epidemiologist at the UKHSA, previously stated that norovirus levels were more significant in April than they typically are at this time of year and have been on the rise.
A combination of factors may have contributed to this, but the colder weather we have experienced is unlikely to have been advantageous.
Consuming an adequate amount of fluids in the event of illness is crucial, as norovirus has the potential to induce dehydration, particularly in susceptible populations such as young children, the elderly, and the immunocompromised.
“In the event that you are experiencing diarrhea and vomiting, it is possible to prevent the transmission of the infection.”
She further stated, “Do not resume work, school, or the nursery until 48 hours have passed since the cessation of your symptoms. Additionally, refrain from preparing food for others during this period.”
To prevent the transmission of the infection in these environments, refrain from visiting individuals in hospitals and care homes while you are ailing.
Washing hands with soap and warm water and using bleach-based products to clean surfaces can also prevent infection transmission.
“Alcohol gels cannot eradicate Norovirus; therefore, they should not be relied upon exclusively.”
Experts also suggest that the current surge may be partially due to COVID restrictions, as fewer individuals have been exposed to norovirus than is typical since the onset of the pandemic.
According to their theory, our bodies may be less capable of combating the infection after years of minimal exposure.
The unprecedented surge in scarlet fever cases, which in 2022 reached the highest reported number since the 1950s, was partially attributed to the exact cause.
However, they also issued a warning that the increase may be attributable to the introduction of new strains of the virus.
Professor Adam Finn, a member of the Government’s vaccine advisory panel at the University of Bristol, stated to MailOnline that the recent numbers are more significant than usual and may still be attributed, at least in part, to the decrease in numbers that occurred during the Covid closure period.
In the aftermath of the pandemic, we continue to observe an anomalous epidemiology in terms of the seasonality of numerous infections and the number of cases. The spring’s relatively unfavorable weather also played a role.

We occasionally observe the emergence of novel norovirus strains against which individuals have little or no immunity from previous infections.
A strain known as G.II.17, which has only recently emerged, has been responsible for approximately 17% of the most recent cases. Therefore, this may also contribute to a higher-than-average number of cases.
He also mentioned that there are vaccines on the horizon, with one of them about to release the results of a phase three trial.
Therefore, it is feasible that we possess the resources to prevent or at least mitigate this issue in the near future.
