A new strain of norovirus is currently spreading in the UK, with cases reaching higher levels than usual for this time of year. The UK Health Security Agency (UKHSA) has identified the dominant strain as GII.17, also known as the ‘Kawasaki’ strain, which now accounts for around 70% of all cases.
Norovirus, commonly referred to as the “winter vomiting bug”, is a stomach bug that causes symptoms such as vomiting, diarrhoea, nausea, stomach pain, high temperature, headaches, and body aches. The ‘Kawasaki’ strain was first detected in Japan in 2014 and has been on the rise in the UK since April 2024.
The virus is highly contagious and can be transmitted through contact with infected individuals, contaminated surfaces, or consuming food and water handled by someone with the virus. It is important to note that alcohol-based hand gels do not effectively kill norovirus, so frequent handwashing with soap and water is recommended to prevent its spread.
Treatment for norovirus mainly involves self-care at home, including staying off school or work, avoiding visits to care homes or hospitals, and waiting 48 hours after symptoms have cleared before returning to communal settings. It is also essential to rest and stay hydrated by drinking plenty of fluids until the illness subsides.
As cases of the ‘Kawasaki’ strain continue to rise, it is crucial to be vigilant about personal hygiene practices to prevent further spread of the virus. Stay informed about the latest updates and guidance from health authorities to protect yourself and others from norovirus.
