Study shows SARS-CoV-2 VOCs disseminated around the world according to different spatial source-sink dynamics

By Bhavana KunkalikarNov 30 2022Reviewed by Danielle Ellis, B.Sc. In a recent study posted to the medRxiv* preprint server, researchers assessed the dispersion patterns of severe acute respiratory syndrome coronavirus 2 variants and their global expansion.

About the study In the present study, researchers employed phylogeographic and phylogenetic techniques to reconstruct the global distribution trends of SARS-CoV-2 VOCs. To examine the correlation between worldwide air travel and the latency in global VOC dispersal, the team estimated pairwise correlations between sampling postponements for each nation for each VOC and the total incoming travel volumes for that country during VOC dispersal, as well as the incoming travel volumes from the presumed origin countries corresponding to each VOC.

Approximately 50% of southern Africa's Beta exports were to areas within the same region. In addition, the researchers inferred significant Beta diffusion to Western Europe from southern Africa and then within Western Europe itself. Africa and Asia were inferred to be a net source of Beta, with exports peaking post-April 2021.
