The country has identified about 100 cases of the variant, mostly from its most populated province, Gauteng, where Johannesburg and Pretoria are located.All viruses - including SARS-CoV-2, the virus that causes COVID-19 - change over time. Most changes have little or no impact on their properties. South African scientists say some of the mutations are associated with resistance to neutralising antibodies and enhanced transmissibility, but others were not well understood, so its full significance is not yet clear.
No unusual symptoms have been reported following infection with the B.1.1.529 variant and, as with other variants, some individuals are asymptomatic, South Africa's National Institute for Communicable Diseases said.South African scientists say early signs from diagnostic laboratories suggest it has spread rapidly in Gauteng and may already be present in the country's other eight provinces.
Scientists say early detection due to genomic surveillance in Botswana and South Africa may have limited the spread of the variant.
