[191] Both types originated in west and central Africa, jumping from other primates to humans.
In 2008, the sample was tested by researchers, identifying partial HIV viral sequences. [8] The specimen, named DRC60 contained a strain of HIV-1 around 88% similar to LEO70, but was found to be most closely related to HIV-1 (M) subgroup A isolates. These two specimens are significant not only because they are the oldest known specimens of HIV ...
