The new strain XE spreads faster than Omicron BA.2: WHO warns that it may be the fastest spreading new coronavirus strain

The British government's official website recently released a report on the recombination of three new coronavirus variants. The data shows that 637 cases of XE (ie the recombination of Omicron BA.1 and BA.2) have been identified in the UK so far. Although the case is rare, it has an extremely high rate of transmission, which means that XE has the potential for a pandemic.

Recombinant variants are produced when an individual is infected with two or more variants of the new coronavirus at the same time, according to the UK government website. While this is not uncommon, several instances of Covid-19 variant recombination have been identified during the Covid-19 pandemic.

"Early investigations suggest that the new variant XE is spreading 10% faster than the currently dominant Omicron BA.2 strain, but the data sample is too small," the WHO said in a report on Wednesday. , it remains to be seen whether it will become a potential threat in the future."
