HIV is a type of lentivirus, which means it attacks the immune system. For all the latest ABC Science content click here. Bythis subtype had caused 75 million infections.

Many of the first cases of AIDS were recorded there chipanzees. As a result, it infects far fewer people, and is mainly found in a few countries in West Africa like Mali, Mauritania, Nigeria and Sierra Leone.

Bailes and her team carried out extensive phylogenetic analyses comparing the structure of different strains of SIV to investigate the question. There are numerous earlier cases where patterns of deaths from common opportunistic infections, now known to be AIDS-defining, suggest that HIV was the cause, but this is the earliest incident where a blood sample can verify infection.

Nevertheless, he agrees the new findings have important implications for public health. You can find out more about the origins and history of HIV through our interactive timelinewhere you can read, watch, listen and explore key events from the history of the epidemic.

They concluded that the SIVcpz strain arose in chimpanzees through a series of transmission and recombination or genetic exchange events between SIVs in two species of monkeys: At first the disease was called all sorts of names relating to the word ‘gay’. This explains why there is more than one strain of HIV Skip to navigation Skip to content.

The lack ib transport routes into the North and East of the country accounts for the significantly fewer reports of infections there at the time. Use these social-bookmarking links to share HIV may be a hybrid mix of monkey viruses.

Cribb also argues such findings have implications for the possible risks of transplants across species, a developing technique known as xenotransplantation. American Museum of Natural History.

Global information and education on HIV and AIDS

Ina few cases of rare diseases were being reported among gay men in New York and California, such as Kaposi’s Sarcoma a rare cancer and a lung infection called PCP. There is now a wealth of evidence on how, when and where HIV first began to cause illness in humans. In this scenario, SIVcpz was transferred ij humans as a result of chimps being killed and eaten, or their blood getting into cuts or origgin on people in the course of hunting.

The same area is known for having the most genetic diversity in HIV strains in the world, reflecting the number of different times SIV was passed to humans.
