Several of the theories of HIV origin accept the established knowledge of the HIV/SIV phylogenetic relationships, and also accept that bushmeat practice was the most likely cause of the initial transfer to humans. All of them propose that the simultaneous epidemic emergences of four HIV groups in the late 19th-early 20th century, and the lack ...
Various fringe theories have arisen to speculate about purported alternative origins for the human immunodeficiency virus (HIV) and the acquired immunodeficiency syndrome (AIDS), with claims ranging from it being due to accidental exposure to supposedly purposeful acts. Several inquiries and investigations have been carried out as a result, and ...
But they are conspiracy theories: the OPV'ers maintain that the government(s)/big pharma/whoever has/have covered up the true origin of AIDS; same with the smallpox people; Thabo Mbeki and his hangers-on stated variously that AIDS (or HIV, or AIDS medications or poverty mislabelled as AIDS) is a plot of racial extermination by whites/foreign ...
HIV is a retrovirus that primarily infects components of the human immune system such as CD4 + T cells, macrophages and dendritic cells. It directly and indirectly destroys CD4 + T cells. [88] HIV is a member of the genus Lentivirus, [89] part of the family Retroviridae. [90] Lentiviruses share many morphological and biological characteristics.
In 2008, the sample was tested by researchers, identifying partial HIV viral sequences. [8] The specimen, named DRC60 contained a strain of HIV-1 around 88% similar to LEO70, but was found to be most closely related to HIV-1 (M) subgroup A isolates. These two specimens are significant not only because they are the oldest known specimens of HIV ...
Duesberg's claim that recreational drug use, rather than HIV, was the cause of AIDS has been specifically examined and found to be false. Cohort studies have found that only HIV-positive drug users develop opportunistic infections; HIV-negative drug users do not develop such infections, indicating that HIV rather than drug use is the cause of AIDS.
Robert Lee Rayford [1] (February 3, 1953 – May 15, 1969), [2] sometimes identified as Robert R. due to his age, was an American teenager from Missouri who has been suggested to represent the earliest confirmed case of HIV/AIDS in North America.
This is a timeline of HIV/AIDS, including but not limited to cases before 1980. Pre-1980s See also: Timeline of early HIV/AIDS cases Researchers estimate that some time in the early 20th century, a form of Simian immunodeficiency virus found in chimpanzees (SIVcpz) first entered humans in Central Africa and began circulating in Léopoldville (modern-day Kinshasa) by the 1920s. This gave rise ...
