On Tuesday, the WHO said a subvariant of the Omicron strain has been detected in 57 countries, reported AFP. The global health body said that subvariants of Omicron, BA.1 and BA.1.1, which were the first versions to be identified, still account for over 96% of all the Omicron sequences uploaded to the GISAID.

However, WHO added that there has been a clear rise in cases involving BA.2, the new subvariant of Omicron.
