The Beta variant,[1][2] (B.1.351),[a] was[5][6] a variant of SARS-CoV-2, the virus that causes COVID-19. One of several SARS-CoV-2 variants initially believed to be of particular importance, it was first detected in the Nelson Mandela Bay[7] metropolitan area of the Eastern Cape province of South Africa in October 2020,[8] which was reported by the country's health department on 18 December 2020.[9] Phylogeographic analysis suggests this variant emerged in the Nelson Mandela Bay area in July or August 2020.[10]
The World Health Organization labelled the variant as Beta variant, not to replace the scientific name but as a name for the public to commonly refer to.[11][12] The WHO considers it to be a variant of concern no longer in circulation.[5]

Spatiotemporal phylogeographic analysis suggests that the 501Y.V2 lineage emerged in early August (early July – end August 2020, 95% highest posterior density) in Nelson Mandela Bay.
