The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance

Investment in Africa over the
past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)
sequencing has led to a massive increase in
the number of sequences, which, to date, exceeds 100,000 sequences generated to track
the pandemic on the continent. These sequences have profoundly affected how public
health officials in Africa have navigated the
COVID-19 pandemic.
have helped monitor the epidemic on the continent, how genomic surveillance expanded
over the course of the pandemic, and how
we adapted our sequencing methods to deal
with an evolving virus. Finally, we also examine how viral lineages have spread across
the continent in a phylogeographic framework to gain insights into the underlying
temporal and spatial transmission dynamics for several variants of concern (VOCs).
