Original Note:
While this could be true for South Africa. It's important to note that gene flow can change this. Since the virus from the US and south Africa is geologically isolated from one another, they each mutate and change differently. Which can change how the virus behaves. https://www.nature.com/scitable/knowledge/library/natural-selection-genetic-drift-and-gene-flow-15186648/
