The UK Health Security Agency (UKHSA) is encouraging the public to wear face masks again to help reduce influenza infections, particularly from the H3N2 strain, which has driven a recent surge in cases this winter. Although recent data from the government indicates a decline in flu hospital admissions and positivity rates, the agency stresses the importance of continued vigilance.
In the week ending December 24, flu positivity rates dropped from 21.1% to 17.2%, while hospital admissions decreased from 9.98 to 7.85 per 100,000 people. Despite these encouraging trends, UKHSA advises individuals to adopt simple preventative measures like mask-wearing, vaccination, and self-isolation when possible.
The UKHSA shared a message on X, stating: “Keep everyone feeling their best this festive season, with a few simple steps which can make a big difference in avoiding flu.”

Face masks remain a critical tool in limiting the spread of respiratory viruses, including influenza and COVID-19. A well-fitting mask can reduce the release of virus-containing particles from the mouth and nose, lowering the risk of transmission and protecting the wearer from direct infection.
Flu vaccination is another key defense. The vaccine exposes the immune system to a small, inactivated part of the virus, prompting the body to build protection. Immunity develops about 10 days after vaccination. Importantly, the flu jab cannot cause the flu itself.
Six groups qualify for a free flu vaccine under NHS guidelines, especially those needing extra protection or who live with vulnerable individuals. Eligible people can book the vaccine through their GP, at pharmacies online, or via the NHS app if aged 18 or over. Some pharmacies also offer free vaccines with walk-in appointments, though availability varies.
By combining vaccination, mask use, and sensible isolation, individuals can significantly reduce their flu risk this season and protect those around them.
