TL;DR: Two new lineages, BA.4 and BA.5 have rapidly replaced BA.2 in South Africa and are identified by the proxy marker of S-gene target failure with the TaqPath COVID-19 qPCR assay.

TL;DR: There is an increase in the number of African countries able to sequence within their own borders, coupled with a decrease in sequencing turnaround time, which underscores the heterogeneous nature of the pandemic.
Journal ArticleDOI
Demographic responses of forest-utilizing bats to past climate change in South Africa
TL;DR: It appears that the lower climate change footprint and refuge-status of eastern South Africa prevented population declines of insectivorous bats during the LGM, and forest-associated species and habitat generalists demonstrated population expansions during the Pleistocene.

TL;DR: It is shown that a single lineage, C.36, introduced early in the pandemic was responsible for most cases in Egypt and to remain dominant in the face of mounting immunity from previous infection and vaccination, this lineage evolved into various sub-lineages acquiring several mutations known to confer adaptive advantage and pathogenic properties.
