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 ...
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 ...
The human immunodeficiency virus (HIV) [8] [9] [10] is a retrovirus [11] that attacks the immune system.It is a preventable disease. [5] It can be managed with treatment and become a manageable chronic health condition. [5]
HIV-1 group M (responsible for the global pandemic) is estimated to have emerged in humans around 1920 near Kinshasa, then part of the Belgian Congo.This estimation was the result of time-scaled evolutionary models being applied to modern samples and retrieved early samples of HIV-1 (M).
The management of HIV/AIDS typically involves the use of multiple antiretroviral drugs. In many parts of the world, HIV has become a chronic condition, with progression to AIDS increasingly rare. HIV latency and the resulting viral reservoir in CD4 + T cells, dendritic cells, and macrophages is the main barrier to eradication of the virus. [19 ...
The dermatologist Alan Cantwell, in self-published books entitled AIDS and the Doctors of Death: An Inquiry into the Origin of the AIDS Epidemic (1988) and Queer Blood: The Secret AIDS Genocide Plot (1993), said that HIV is a genetically modified organism developed by U.S. Government scientists.
The OPV AIDS hypothesis relates only to the historical origin of AIDS, and its proponents have accepted the safety of the modern polio vaccines, but rumors based on a misunderstanding of the hypothesis exist, [46] [47] and those rumors are blamed in part for the recent failure to eliminate polio in Nigeria.

Although AIDS is a global disease, the CDC reports that Sub-Saharan Africa has the highest prevalence of HIV and AIDS worldwide, and accounts for approximately 61% of all new HIV infections. Other regions significantly affected by HIV and AIDS include Asia and the Pacific, Latin America and the Caribbean, Eastern Europe, and Central Asia.
