A New Covid variant in South Africa- What should we know?

-

The World Health Organization (WHO) categorized a new variant of SARS-CoV-2, presently spreading in South Africa, as a ‘variant of concern’ and named it 'Omnicron'.

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

New variants continue to rise as SARS-CoV-2 spreads, and the importance of each mutation becomes known after some time. 

From what is known currently, B.1.1.529 has multiple spike protein mutations, and preliminary analysis recommends it is highly infectious. South Africa has reported a four-fold increase in new cases over the last two weeks, coinciding with the emergence of B.1.1.529.
