A Covid variant of mutation called XE has emerged in the UK, which is believed to be more transmissible than Omicron.
XE is a recombinant of both sub-variants (BA.1 and BA.2) of Omicron, which appears to be 10 per cent more transmissible than the BA.2 sub-variant of Omicron.
The global health body WHO suggests that it could be more transmissible than any other Covid strain so far.
