Britons have been urged to wear a mask in public if feeling unwell, as the NHS faces a "tidal wave" of illness ahead of Christmas.
The UK Health Security Agency (UKHSA) issued advice on how to avoid catching and spreading flu, Covid-19, and other respiratory illnesses this winter.
This year's flu season started earlier than usual and is yet to reach its peak, with experts concerned about a "drifted influenza A(H3N2) strain".
Flu admissions to English hospitals have reached record highs for this time of year, with 1,717 daily admissions last week, a 56 per cent increase from the previous year.
