Global information and education on HIV and AIDS

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. The first verified case of HIV is from a blood sample taken in from a man living in what is now Kinshasa in the Democratic Republic of Congo.

This is the strain that can also infect humans. Latest features web feed. We will not hold your personal data or use it for any other purpose. Apart from suggesting the current strains of HIV are likely to recombine in an unpredictable fashion – making the task of developing vaccines and treatments even more challenging than it already is – Cribb believes the findings have important implications for our understanding of retroviruses, the group of viruses to which SIV and HIV belong.

There is now a wealth of evidence on how, when and where HIV first began to cause illness in humans. Many of the first cases of AIDS were recorded there too.

Origi the editor Share this article Krigin a friend. HIV first began to spread along the historic trade routes of the Congo basin in the s. At first the disease was called all sorts of names relating to the word ‘gay’.

Studies of some of the earliest known samples of HIV provide clues about when it first appeared in humans sov how it evolved. Please let us know any comments you have about the content on this page. Bythis subtype had caused 75 million infections.

Bailes and colleagues note that chimpanzees prey on both of these species, and their territorial ranges overlap in west central Africa. American Museum of Natural History. The area also had a growing sex trade around the time that HIV chimpanzzees to spread.

At this time, many Haitian professionals who were working in the colonial Democratic Republic of Congo during the s returned to Haiti. When it transmutes into HIV, it becomes one of the worse killers of human beings and Asian monkeys.

The same scientists then conducted more research into how SIV could have developed in the chimps. Julian Cribb, an Australian science writer and author of a book on the origin of AIDS, believes there is no evidence to support the idea that SIVcpz arose as a result of chimpanzees eating monkeys. In this scenario, SIVcpz was transferred to humans as a result of chimps being killed and eaten, or their blood getting into cuts or wounds 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.

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. When to get tested?


Rather than small incremental changes in characteristics due to straight-forward Darwinian evolution, retroviruses are capable of changing in huge jumps as a result of genetic recombination, Cribb said.

As a inn, it infects far fewer people, and is mainly found in a few countries in West Africa like Mali, Mauritania, Nigeria and Sierra Leone. Byit had reached Brazzaville, about km west of Kinshasa.

Where are we now? The lack of transport routes into the North and East of the country accounts for the significantly fewer reports of infections there at the time. The high population of migrants and sex trade might explain how HIV spread along these infrastructure routes. Please enable it in your browser settings.

Bailes and her team carried out extensive phylogenetic analyses comparing the structure of different strains of SIV to investigate the question.
