From the Document: "Sub-Saharan Africa has confirmed fewer COVID-19 [coronavirus disease 2019] cases and deaths per capita than other regions, but many countries have faced a deadlier third wave of cases since mid-2021. As of July 2021, southern African countries had the highest per-capita caseloads (and had also administered the most tests). Public health experts have expressed acute concerns about the regional surge in both cases and deaths, which they attribute to the spread of the highly transmissible Delta variant and public fatigue with infection control restrictions. Most governments in Africa have struggled to secure vaccines. Total cumulative confirmed cases and deaths remain concentrated in a handful of countries, led by South Africa. Studies suggest that case data may be underreported in many countries, and experts warn that asymptomatic transmission may have hidden the scope of the spread while allowing for potential virus mutation."
