There are different sub-types of HIV. Strangely enough the subtype B, which is one mainly affecting the West, isn't found much in West Africa.

“Within the HIV-M group, there is a further division into at least ten subtypes or clades (groups of genetically related virus). Historically, the distribution of subtypes followed the geographic patterns listed below.
Subtype A: Central and East Africa as well as East European countries that were formerly part of the Soviet Union.
Subtype B: West and Central Europe, the Americas, Australia, South America, and several southeast Asian countries (Thailand, and Japan), as well as northern Africa and the Middle East.
Subtype C: Sub-Saharan Africa, India, and Brazil.
Subtype D: North Africa and the Middle East.
Subtype F: South and southeast Asia.
Subtype G: West and Central Africa.
Subtypes H, J, and K: Africa and the Middle East.”

“In India, a study comparing the relative transmission efficiency of HIV-1 subtypes A and C in vitro, showed that subtype C isolates were able to replicate and transmit (higher transmission efficiency across cervical mucosa) than subtype A isolates”
Studies indicate that the different subtypes might "transmit" better via certain routes than others, Eg based on that Indian study, it suggests that subtype C would be more likely to transmit via vaginal sex than subtype A.
