CLEAN : Inside the South African lab that discovered Omicron

The transcript discusses the investigation of a new virus variant in Johannesburg, initially thought to be an alpha variant. After sequencing, it was identified as a different virus, leading to the discovery of Omicron. The data was shared with national agencies, confirming similar findings across the country. Omicron quickly displaced the Delta variant within two weeks, raising questions about its transmissibility and the role of public behavior in its spread.
