The World Health Organisation (WHO) has issued a warning about a new Covid variant which is apparently the "most transmissible yet".
Subvariant XBB.1.5 is spreading rapidly through the United States. Cases have shot up from four percent to 40 percent in December and it's thought to be causing around 70 percent of new infections.
The surge has sparked concerns over how well the UK is prepared to handle a fresh Covid wave due to the ongoing pressure on the NHS and hospitals, the The Mirror reports.
