OMICRON VARIANT

Nov. 27, 2021

The World Health Organization (WHO) classified a new variant of SARS-CoV-2, currently circulating in South Africa, as a ‘variant of concern’. It also named it Omicron.

About:

The Network for Genomics Surveillance in South Africa (NGS-SA) had identified the variant. It had detected a group of related SARS-CoV-2 viruses, which belong to a lineage named B.1.1.529.
Early indications are that this variant is possibly even more transmissible than the highly infectious Delta variant, and that current vaccines may be less effective against it.
From what is known currently, B.1.1.529 has multiple spike protein mutations, and preliminary analysis suggests it is highly infectious.
1.1.529 has “very unusual constellations of mutations” — with 30 in the region that encodes the spike protein, which is responsible for the virus’s entry in human cells.
