The primary means of transmission worldwide is sexual contact with an infected individual. Research in this area is conducted using molecular phylogenetics, comparing viral genomic sequences to determine relatedness. Scientists generally accept that the known strains (or groups) of HIV-1 are most closely related to the simian immunodeficiency viruses (SIVs) endemic in wild ape populations of West Central African forests. In particular, each of the known HIV-1 strains is either closely related to the SIV that inf…
