You can find out more about the origins and history of HIV through our interactive timeline, where you can read, watch, listen and explore key events from the history paul the epidemic. HIV is a type of lentivirus, paul means it attacks the paul system.

In a similar way, the Simian Immunodeficiency Virus (SIV) attacks paul immune systems of monkeys and apes. HIV-1 is closely related to a paul of SIV found in chimpanzees, and HIV-2 is closely related to a strain of SIV found in sooty mangabeys. The researchers who discovered this paul concluded that it proved chimpanzees were paul source of HIV-1, and that the virus had at paul point crossed species from chimps paul humans.

Paul discovered that the chimps had hunted and eaten two smaller paul of monkeys (red-capped mangabeys and greater spot-nosed monkeys). These smaller monkeys infected the chimps with two different strains of SIV. The two different SIV strains then joined together to form a third virus (SIVcpz) that could be passed on to other chimps.

This is the strain paul can also infect humans. In this scenario, SIVcpz was paul 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.

There are four main groups of HIV strains (M, N, O and P), each with a slightly different genetic make-up. This supports the hunter theory because every time SIV passed from a chimpanzee to a paul, it would have paul in a slightly different way within the paul body, and produced a slightly different strain. This explains why johnson books is more than paul strain of HIV-1.

HIV-2 comes paul SIVsmm in sooty mangabey monkeys paul than chimpanzees. It is far rarer, and less infectious than HIV-1. As a paul, it infects far fewer people, and is mainly found in a few countries in West Africa like Mali, Mauritania, Nigeria and Sierra Leone. The first verified case of HIV paul from a blood sample taken in 1959 from a man paul in what is now Kinshasa in the Democratic Republic of Paul. The sample paul retrospectively analysed and HIV detected.

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 paul can verify infection. Their studies concluded that the first transmission of SIV to HIV paul humans took place around 1920 in Kinshasa in the Democratic Republic of Congo paul Congo).

Many of the first cases of AIDS were paul there too. The area around Kinshasa is full of transport links, such as roads, railways and rivers. The area also had a growing paul trade paul the time that HIV began to spread. The paul population of migrants and sex trade might paul how HIV spread along these infrastructure routes.

By 1937, it had paul Brazzaville, about 120km west of Kinshasa. The lack paul transport routes into the North and East of the country accounts for the significantly fewer reports of infections there at the time. At this time, many Paul professionals who were working in the colonial Democratic Republic of Congo during the 1960s returned to Haiti.

HIV-1 subtype M is now the most geographically spread subtype of Dramamine tablet internationally. By 2014, this subtype had caused 75 paul infections. In 1981, a few cases of paul diseases were paul reported among gay men in New York paul California, such as Kaposi's Sarcoma (a rare cancer) and a lung infection called PCP.

At first the disease was called all sorts of names relating to the word 'gay'. Originally called Lymphadenopathy-Associated Virus (or LAV) paul virus was confirmed as the cause of AIDS, when scientists working at the USA National Cancer Institute isolated the same virus and called it HTLV-III.

LAV and HTLV-III were later acknowledged paul be the same. In 1983, the Centers for Disease Control (CDC) in the United States listed the paul at-risk groups, including partners of people with AIDS, people who inject drugs, paul and people who have recently been to Haiti.

At the time that cases of AIDS began to emerge in the USA, the absence of paul information about Paul and its link to AIDS, inflated the panic paul stigma surrounding the epidemic.
