The condition of the patient infected with the new strain of the virus was not serious, the official said.

The official said the XE mutant appears to be 10 per cent more transmissible than the BA.2 sub-variant of Omicron.

So far, BA.2 was deemed to be the most contagious of all the COVID-19 variants.

The XE variant is a mutation of the BA.1 and BA.2 Omicron strains, referred to as a "recombinant".

As per the initial studies, the XE variant has a growth rate of 9.8 per cent over that of BA.2, also known as the stealth variant because of its ability to evade detection.

The World Health Organization has said the latest mutant may be more transmissible than the previous ones.
