  • Summary

    Chapter 2 explains how scientists identified the simian source of HIV. It starts with a short biography of Jane Goodall, some of whose findings, which were based on decades of observing chimpanzees in the Gombe Reserve, Tanzania, provided important clues. The distribution of various types of chimpanzees in Africa and key aspects of their behaviours are reviewed. This chapter also examines how, based on genetic studies of viruses that infect apes in the wild, scientists concluded that the Pan troglodytes troglodytes chimpanzee, which inhabits parts of central Africa, is the source of the HIV virus. This simian virus, SIVcpz, is identical to HIV-1.
