What was discovered

A study of wild chimpanzee faeces from Cameroon found SIVcpz viruses closely related to HIV-1 group M, the cause of the pandemic. It located the source in the Pan troglodytes troglodytes populations of the southeast.

HIV-1 groups M and N derive from chimpanzees of southeast Cameroon, and groups O and P from gorillas (D'Arc, 2015). Transmission is assumed to have occurred through bushmeat hunting.

What it led to

  • identification of the zoonotic jump of HIV
  • surveillance of simian viruses
  • reconstruction of the early history of AIDS
