Of HIV-1, in green, budding from cultured is caused by a (HIV), which was originated in non-human in and. While various sub-groups of the virus acquired human infectivity at different times, the global pandemic had its origins in the emergence of one specific strain – HIV-1 subgroup M – in in the (now Kinshasa in the ) in the 1920s. Two types of HIV exist: and. HIV-1 is more virulent, is more easily transmitted and is the cause of the vast majority of HIV infections globally. The pandemic strain of HIV-1 is closely related to a virus found in of the subspecies, which live in the forests of the Central African nations of,,, (or Congo-Brazzaville), and. HIV-2 is less transmittable and is largely confined to West Africa, along with its closest relative, a virus of the ( Cercocebus atys atys), an Old World monkey inhabiting southern,,,,, and western. Main article: In 1975 and 1976, a sailor, with the alias name, his wife, and his seven-year-old daughter died of AIDS. The sailor had first presented symptoms in 1969, eight years after he first spent time in ports along the West African coastline. A infection during his first African voyage shows he was sexually active at this time. Tissue samples from the sailor and his wife were tested in 1988 and found to contain HIV-1 (Group O). 1973: Ugandan children [ ] From 1972 to 1973, researchers drew blood from 75 children in to serve as controls for a study of. In 1985, retroactive testing of the frozen blood serum indicated that antibodies to a virus related to HIV were present in 50 of the children. Spread to the Western Hemisphere [ ] HIV-1 strains were once thought to have arrived in from Haiti around 1971. It spread from to around 1976. HIV-1 is believed to have arrived in Haiti from central Africa, possibly from the around 1967. The current consensus is that HIV was introduced to Haiti by an unknown individual or individuals who contracted it while working in the Democratic Republic of the Congo circa 1966, or from another person who worked there during that time. A mini-epidemic followed, and, circa 1969, yet another unknown individual took HIV from Haiti to the United States. The vast majority of cases of AIDS outside sub-Saharan Africa can be traced back to that single patient (although numerous unrelated incidents of AIDS among Haitian immigrants to the U.S. Were recorded in the early 1980s, and, as evidenced by the case of, isolated incidents of this infection may have been occurring as early as 1966). The virus eventually entered male gay communities in large United States cities, where a combination of casual, multi-partner sexual activity (with individuals reportedly averaging over 11 unprotected sexual partners per year ) and relatively high transmission rates associated with allowed it to spread explosively enough to finally be noticed. Because of the long incubation period of HIV (up to a decade or longer) before symptoms of AIDS appear, and, because of the initially low incidence, HIV was not noticed at first. By the time the first reported cases of AIDS were found in large United States cities, the prevalence of HIV infection in some communities had passed 5%. Worldwide, HIV infection has spread from urban to rural areas, and has appeared in regions such as China and India. Canadian flight attendant theory [ ]. Main article: A Canadian named was referred to as 'Case 057' and later 'Patient O' for 'outside Southern California', in an early AIDS study by Dr. Because of this, many people had considered Dugas to be responsible for taking HIV to North America. However, HIV reached around 1971 while Dugas did not start work at until 1974. In ' 1987 book (and the 1993 movie based on it), Dugas is referred to as AIDS' instead of 'Patient O', but neither the book nor the movie states that he had been the first to bring the virus to North America. He was incorrectly called 'Patient Zero' because at least 40 of the 248 people known to be infected by HIV in 1983 had had sex with him, or with someone who had sexual intercourse with him. 1981-1982: From GRID to AIDS [ ] The AIDS epidemic officially began on June 5, 1981, when the U.S. In its newsletter reported unusual clusters of caused by a form of (now recognized as a distinct species ) in five homosexual men in Los Angeles. Over the next 18 months, more PCP clusters were discovered among otherwise healthy men in cities throughout the country, along with other opportunistic diseases (such as and persistent, generalized lymphadenopathy ), common in patients.

In June 1982, a report of a group of cases amongst gay men in suggested that a might be the agent, and the syndrome was initially termed 'GRID',. Health authorities soon realized that nearly half of the people identified with the syndrome were not homosexual men. The same opportunistic infections were also reported among, users of such as heroin, and Haitian immigrants – leading some researchers to call it the '4H' disease. By August 1982, the disease was being referred to by its new CDC-coined name: Acquired Immune Deficiency Syndrome (AIDS). Identification of the virus [ ] May 1983: LAV [ ] In May 1983, doctors from Dr. 's team at the in France reported that they had isolated a new from that they believed was the cause of AIDS. The virus was later named lymphadenopathy-associated virus (LAV) and a sample was sent to the U.S. Centers for Disease Control, which was later passed to the (NCI). May 1984: HTLV-III [ ] In May 1984 a team led by of the United States confirmed the discovery of the virus, but they renamed it human T lymphotropic virus type III (). August 1984: ARV [ ] Dr. Jay Levy's group at the University of California, San Francisco also played a role in the discovery of HIV. He independently isolated the AIDS virus in 1983 and named it the AIDS-associated Retrovirus (ARV). January 1985: both found to be the same [ ] In January 1985, a number of more-detailed reports were published concerning LAV and HTLV-III, and by March it was clear that the viruses were the same --- indeed, it was later determined that the virus isolated by the Gallo lab was from the lymph nodes of the patient studied in the original 1983 report by Montagnier --- and were the etiological agent of AIDS. May 1986: the name HIV [ ] In May 1986, the ruled that both names should be dropped and a new name, HIV (Human Immunodeficiency Virus), be used. Nobel [ ] Whether Gallo or Montagnier deserve more credit for the discovery of the virus that causes AIDS has been a matter of. Together with his colleague, Montagnier was awarded one half of the 2008 for his 'discovery of human immunodeficiency virus'. Also shared the prize for his discovery that leads to, but Gallo was left out. Gallo said that it was 'a disappointment' that he was not named a co-recipient. Montagnier said he was 'surprised' Gallo was not recognized by the Nobel Committee: 'It was important to prove that HIV was the cause of AIDS, and Gallo had a very important role in that. I'm very sorry for Robert Gallo.' Dr Levy’s contribution to the discovery of HIV was also cited in the Noble Prize ceremony. Case definition for epidemiological surveillance [ ] Since June 5, 1981, many definitions have been developed for surveillance such as the and the. Genetic studies [ ]. Further information: According to a study published in the in 2008, a team led by Robert Shafer at has discovered that the has an (the genus to which HIV belongs) in its genetic makeup. This suggests that lentiviruses have existed for at least 14 million years, much longer than the currently known existence of HIV. In addition, the time frame falls in the period when Madagascar was still connected to what is now the African continent; the said lemurs later developed immunity to the virus strain and when the lentivirus was widespread among other. The study is being hailed as crucial, because it fills the blanks in the origin of the virus, as well as in its evolution, and may be important in the development of new antiviral drugs. In 2010, researchers reported that had infected monkeys in for at least 32,000 years. Previous to this time, it was thought that SIV infection in monkeys had happened over the past few hundred years. Scientists estimated that it would take a similar amount of time before humans adapted naturally to HIV infection in the way monkeys in Africa have adapted to SIV and not suffer any harm from the infection. A 2016 Czech study of the genome of, an order of mammals parallel to primates and sharing an immediate common ancestor with them, found endogenous lentiviruses that emerged an estimated 40-60 million years ago based on rates of viral mutation versus modern lentiviruses. Discredited hypotheses [ ]. Main article: Other hypotheses for the origin of AIDS have been proposed. Argues that HIV or AIDS does not exist or that AIDS is not caused by HIV; some of its proponents believe that AIDS is caused by lifestyle, including sexuality or drug use, and not by HIV. Some conspiracy theories allege that HIV was created in a bioweapons laboratory, perhaps as an agent of or an accident. These hypotheses have been rejected by; it is generally accepted among pathologists that 'the evidence that HIV causes AIDS is scientifically conclusive', and most 'scientific' arguments for denialism are based on misrepresentations of outdated data.
