Implication

Genomic surveillance study uncovers distinct variant dispersal dynamics across African nations, highlighting the critical role of domestic sequencing capacity for pandemic preparedness.

Key Points

To evaluate the expansion of SARS-CoV-2 genomic sequencing capacity across Africa and investigate the dispersal patterns of major variants of concern throughout the continent.
Tracked genomic surveillance outputs across African countries as sequencing capacity scaled beyond 100,000 viral genomes.
Assessed sequencing turnaround times and the geographical distribution and transmission dynamics of emerging variants.
Domestic sequencing capacity expanded across multiple countries, yielding shorter turnaround times and facilitating more consistent routine surveillance.
Surveillance uncovered heterogeneous epidemic trajectories alongside distinct continental dispersal dynamics for the Alpha, Beta, Delta, and Omicron variants of concern despite low regional testing proportions.
