The NHS has urged people experiencing diarrhoea or vomiting to avoid visiting hospitals, as cases of norovirus, including the GII.17 'Kawasaki bug' variant, surge. The plea aims to reduce pressure on healthcare services during the winter season.
GII.17, a highly contagious genotype of norovirus, has become the most frequently detected type, surpassing the previously dominant GII.4 strain. The UK Health Security Agency (UKHSA) warns that having had one genotype does not fully protect against the other, meaning people may catch norovirus multiple times this season.
In a Facebook video, an emergency care nurse from North Tees and Hartlepool NHS Foundation Trust advised: 'If you've had any diarrhoea or vomiting in the last 48 hours, please wait to visit your relatives in hospital. You might feel better, but you could still pass the infection on.' The trust added: 'Help stop the spread of infection this winter to protect your local community, loved ones and healthcare services.'
UKHSA epidemiologist Amy Douglas emphasised simple prevention measures: 'Wash your hands with soap and warm water, use bleach-based products to clean surfaces, and avoid visiting hospitals or care homes until 48 hours after symptoms stop. Alcohol gels do not kill norovirus.'
Norovirus typically resolves within two to three days, with symptoms including sudden vomiting and diarrhoea. The NHS advises staying hydrated and seeking pharmacist advice for signs of dehydration, particularly in children, older adults, or those with weakened immune systems.
