Phylogeographic analysis reveals an ancient East African origin of human herpes simplex virus 2 dispersal out-of-Africa

Abstract

There are competing hypotheses for human herpes simplex virus 2’s migration out-of-Africa. Here, the authors sequence 65 new herpes simplex virus 2 genomes with a focus on under-sampled sub-Saharan African countries, suggesting an Eastern African origin for global dispersal the virus between 22-29 thousand years ago.
