Abstract: The A.23 viral lineage, characterized by three
spike mutations
F157L,
V367F and
Q613H, was first identified in
COVID-19 cases from a Ugandan prison in July 2020, and then was identified in the general population with additional
spike mutations (
R102I,
L141F,
E484K and
P681R) to comprise lineage A.23.1 by September 2020, with this virus being designated a variant of interest (VOI) in Africa and with subsequent spread to 26 other countries.
Introduction: Within lineage A, the A.23 viral lineage, was first identified in a Ugandan prison in July 2020, and was characterized by three
