A new coronavirus variant, called XE, has been identified in the UK. The latest research from the UK Health Security Agency (UKHSA) reveals that XE is a mutation of the BA.1 and BA.2 Omicron strains, referred to as a 'recombinant'.
As of 22 March, there have been a confirmed 637 cases of XE in the UK, with the earliest recorded on 19 January 2022. According to the most recent data, as of 16 March 2022, the variant had a growth rate 9.8 per cent above that of the stealth variant, the UKHSCA said.
But the body cautioned that 'as this estimate has not remained consistent as new data have been added, it cannot yet be interpreted as an estimate of growth advantage for the recombinant.' "Numbers were too small for the XE recombinant to be analysed by region," the UKHSCA said.
