New contagious strain sweeps UK – symptoms and how to treat it

A new strain of norovirus, known as the ‘Kawasaki bug’, is rapidly spreading across the UK, with the Health Security Agency (UKHSA) advising individuals with symptoms to stay at home. The Kawasaki strain, or GII. 17, now makes up approximately 70% of cases in the UK. Dr. John Burke from AXA Health has highlighted the contagious nature of norovirus, with cases doubling compared to the previous year.

This strain was first identified in Kawasaki, Japan, in 2014 and has since gained prevalence in the UK. Gauri Godbole, deputy director of gastrointestinal infections at the UKHSA, emphasised the importance of staying home if experiencing symptoms to prevent further spread. Norovirus is highly contagious and can lead to sickness and diarrhoea, especially during the autumn and winter months when people spend more time in close proximity indoors.

Symptoms of norovirus include nausea, diarrhoea, vomiting, high temperature, headache, and body aches, typically appearing suddenly within a day or two. Self-treatment at home with rest and hydration is crucial to recovery, usually within two to three days. The NHS advises individuals to stay off school or work until at least two days after symptoms have ceased to prevent spreading the virus.

Regular hand washing with soap and water is recommended to reduce transmission, as alcohol hand gels are ineffective against norovirus. Seeking medical advice is necessary if symptoms persist or if there are concerns about dehydration, especially in children. Prevention measures, such as avoiding contact with infected individuals and practicing good hygiene, are key to limiting the spread of norovirus.

In conclusion, the emergence of the Kawasaki strain of norovirus in the UK is a concerning development, requiring vigilance and adherence to health guidelines to prevent further infections. Awareness of symptoms, prompt self-isolation, and practicing proper hygiene are crucial in combating the spread of this highly contagious virus.
