“Omicron is currently the dominant variant circulating globally, accounting for >98% of viral sequences shared on GISAID after February 2022,” the World Health Organisation (WHO) said in a statement on November 29, 2022.
“In light of the widespread transmission of the Omicron VOC across the globe and the subsequent expected increased viral diversity, WHO has added a new category to its variant tracking system, termed “Omicron subvariants under monitoring” to signal to public health authorities globally, which VOC lineages may require prioritized attention and monitoring,” the global health agency has said.
Omicron has remained the dominant strain this year. The virus has mutated several times and so far only its sub variants have been detected.
