Kawasaki norovirus makes its way to the UK, identified as the latest strain of the ‘winter vomiting bug’ by the Daily Record. The UK Health Security Agency (UKHSA) has reported that the Kawasaki strain, also known as GII.17, is currently responsible for approximately 70 per cent of all cases of the norovirus in the country. This strain has shown a significant increase in activity, reaching unusually high levels for this time of year.
According to the Mirror, between October 14 and 27, norovirus activity was 16 per cent higher compared to the previous two-week period, with reports exceeding double the five-season average for the same timeframe. The UKHSA suggests that various factors may have contributed to the surge in reported cases, including changes in epidemiology following the COVID-19 pandemic and modifications in testing and reporting for national surveillance.
The Kawasaki norovirus, named after the Japanese city where it was first identified in 2014, poses symptoms such as vomiting, diarrhoea, high temperature, abdominal pain, and aching limbs. It is crucial to note that norovirus can lead to dehydration, particularly in young children, older adults, and individuals with weakened immune systems.
The NHS warns that norovirus is highly contagious and can spread easily through close contact with an infected person, touching contaminated surfaces or objects, or consuming food prepared by someone with the virus. Practising frequent handwashing with soap and water is the most effective measure to prevent the spread of the virus, as alcohol-based hand sanitizers do not eliminate it.
Amy Douglas, an epidemiologist at UKHSA, stated, “The usual increase we see in norovirus cases heading into the winter has started earlier compared to previous seasons,” adding that while there are more cases of a specific strain this year, there is no indication that it leads to more severe illness. She advised individuals with symptoms to refrain from returning to work, school, or preparing food for others until 48 hours after the symptoms have ceased.
In summary, the Kawasaki norovirus, a new strain of the winter vomiting bug, has emerged in the UK, with a rapid increase in reported cases. Health authorities are urging the public to practice proper hand hygiene and take necessary precautions to prevent the spread of the virus, especially during the ongoing COVID-19 pandemic. Prompt identification, isolation, and hygiene measures are paramount in controlling the transmission of norovirus and safeguarding public health.
