Norovirus infections are still at elevated levels, as indicated by a recent alert issued by the UK Health Security Agency. Surveillance laboratories have reported a 50% increase in cases compared to the average of the past five seasons for this time of year. Health officials have noted a spike in cases among individuals aged 65 and above, who are more susceptible to severe infections. There has also been a rise in outbreaks within hospital wards.
Amy Douglas, the lead epidemiologist at the UKHSA, highlighted the persistent high numbers of norovirus cases, especially among the elderly. To combat the spread of the virus, she emphasized the importance of simple preventive measures such as regular handwashing with soap and warm water, and using bleach-based products to disinfect surfaces. Alcohol-based gels are not effective against norovirus.
Individuals experiencing symptoms like diarrhea and vomiting, or those caring for someone with these symptoms, are advised to stay home until at least 48 hours after the symptoms have ceased. It is also recommended to avoid preparing food for others during this period and refrain from visiting hospitals and care homes to prevent spreading the virus to vulnerable individuals.
Asthma + Lung UK cautioned that norovirus poses a particular risk to people with asthma. Helen Sinton, head of services at the charity, explained that while norovirus primarily affects the gastrointestinal system, it can exacerbate asthma symptoms, leading to increased breathing difficulties. Those with worsening symptoms are advised to seek medical attention promptly, and in cases of severe breathing problems, to call emergency services.
Encouragingly, surveillance data suggests that norovirus infections may have reached their peak and are beginning to decline. Recent NHS data indicates a decrease in the number of patients hospitalized in England due to norovirus, marking the first decline since the beginning of the year.
The latest statistics from hospital performance reports in England show a decrease in the average daily number of occupied beds by individuals with diarrhea, vomiting, or norovirus-like symptoms. This decline follows the previous week’s peak, reflecting the first week-over-week decrease in norovirus patients since late December.
Furthermore, respiratory surveillance data indicates a decreasing trend in flu and RSV cases since the start of the year. Dr. Ellen Fragaszy, lead epidemiologist at the UKHSA, emphasized the need for continued vigilance despite the decline, especially when interacting with vulnerable populations and visiting hospitals and care facilities.
The NHS recommends contacting medical services if symptoms of diarrhea persist for more than seven days or if vomiting continues for more than two days.
