On November 26 the World Health Organization converged to discuss an emerging variant of COVID-19. The highly mutated variant, given the name Omicron, first emerged in South Africa and has since been found in at least 15 other countries.

The discovery of this new variant follows the observation of the Mu variant in January 2021, and the emergence of the Delta variant in December 2020, which is still responsible for the vast majority of COVID infections.
