Phylogeny and the origin of HIV-1
Article Abstract:
Research into the phylogenetic tree structure of HIV-1 virus is discussed. The distinctive structure of viruses obtained in the Democratic Republic of Congo suggests that HIV did not have its origin in multiple cross-species transmission as a result of oral polio vaccination.

Sexual transmission of HIV in Africa
Article Abstract:
Epidemiologists analyze and compare route of infection statistics of HIV in sub-Saharan Africa. The article concludes that the main route of infection is still sexual and not trending toward parenteral, as previously thought, and that encouragement of safe sex remains an urgent priority.

Origin of HIV-1 in the chimpanzee Pan troglodytes troglodytes
Article Abstract:
The human AIDS viruses human immunodeficiency virus HIV-1 and HIV-2 represent cross-species or zoonotic infections. Viruses related to HIV-1 were isolated in the common chimpanzee Pan troglodytes, although only three such SIV cpz infections have been documented. The genome of a new SIVcpz strain (SIVcpzUS) has now been sequenced, determining the subspecies identify of all known SIVcpz-infected chimpanzees. Both P.t. troglodytes and P.t. schweinfurthii are found to harbour SIVcpz, and the respective viruses form two highly divergent phylogenetic lineages. HIV-1 strains infecting man are closely linked to one of the SIVcpz lineages found in P.t. troglodytes.
