From the Document: "Sub-Saharan Africa ('Africa') has confirmed far fewer COVID-19 [coronavirus disease 2019] cases and deaths per capita than many other regions to date, but a second, deadlier wave of cases has hit many African countries since late 2020. Confirmed cases remain concentrated in a handful of countries, led by South Africa. South Africa also has conducted the most COVID-19 tests in absolute terms, and in late 2020 discovered a new, more virulent variant of the virus that has spread worldwide. Africa's estimated case fatality rate surpassed the global average in early 2021, possibly due, in part, to the emergence of new virus variants."
