how the aids disease originated?

Answer 1

some believe it came from mokeys, some believe it came from gay people, some believe it was a government experiment gone wrong.. we may never know..

Answer 2

In Africa.
A couple of possible ways.
In monkeys and transfered to human population, a very strong possibility.
It seemed to start in the gay community, so perhaps we had a gay "playing" with a monkey. It seems a likely idea anyway, or someone who just had a monkey as a normal pet without anything kinky and the virsus jumped species.
Or it could have been an escaped gov lab germ experiment as primates are often used to test things on because they are similar to humans. Also pretty likely.
Your guess???

Answer 3

in simple terms examining those solutions makes me wince. Youtube isn't a respectable, precise or clinical source...you're about as likely to take heed to myths and legends as you're technology. Neither of both theories you've given are in any respect precise or clinical, nor are they both major theories. the most likely reason for the inspiration of HIV (please note that's spelt AIDS, no longer help's) is that that's on the concern of a monkey virus - "because particular lines of SIVs undergo an exceedingly close resemblance to HIV-a million and HIV-2, both kinds of HIV." "In February 1999 a collection of researchers from the college of Alabama presented that they had discovered a kind of (''Simian' or monkey virus) that develop into almost the picture of HIV-a million. this actual rigidity develop into stated in a frozen pattern taken from a captive member of the sub-crew of chimpanzees ordinary as Pan troglodytes troglodytes (P. t. troglodytes), that were once common in west-mandatory Africa. The researchers (led through Paul Sharp of Nottingham college and Beatrice Hahn of the college of Alabama) made the discovery in the course of the approach a 10-twelve months lengthy study into the origins of the virus. They claimed that this pattern proved that chimpanzees were the source of HIV-a million, and that the virus had in some unspecified time sooner or later crossed species from chimps to people. Their very last findings were printed 2 years later in Nature mag. suitable right here article, they concluded that wild chimps were contaminated concurrently with 2 diverse simian immunodeficiency viruses which had "viral sex" to sort a third virus that would want to correctly be surpassed on to different chimps and, extra heavily, develop into able to infecting people and causing AIDS. those 2 diverse viruses were traced again to a SIV that contaminated red-capped mangabeys and one present day in additional suitable spot-nosed monkeys. they believe that the hybridisation got here about interior chimps that had develop into contaminated with both lines of SIV once they hunted and killed both smaller species of monkey. in addition they concluded that each and every individual 3 'communities' of HIV-a million - really crew M, N and O - got here from the SIV present day in P. t. troglodytes, and that each and every crew represented a separate crossover 'journey' from chimps to people."

Answer 4

AIDS is thought to have originated in sub-Saharan Africa during the 20th century. It was transferred to humans by a similar route as some classic Old World infectious diseases. The ancient Old World was the incubator of many diseases like smallpox because it had large human populations in close association with large animal populations, especially those that lived in herds or social groups.

Spread from animal to human populations
HIV originated in primates as far as is known. Possible ways for this virus to have originally infected humans include the hunting and eating of the original primate species; a bite would be another possible route. From this point, the virus ultimately spread to the rest of the world.

Since a cross species jump is most likely the origin of HIV, and since HIV became a true epidemic, transmissible from human to human, then the following conditions were needed:

A large human population,
A large nearby population of the appropriate host animal,
An infectious pathogen in the host animal, that eventually produces a mutation that can spread from animal to human,
Interaction between the species to transmit enough of it to humans to establish a human foothold, which may take millions of individual exposures,
A mutation of same pathogen that can spread from human to human,
Some method that allows the pathogen to disperse widely. This prevents the infection from "burning out" by either killing off its human hosts or provoking immunity in a local population of humans.
Such requirements existed in the remote past with smallpox, and also with the 20th century Spanish Flu, despite the latter's New World origin at Fort Riley, Kansas (there the animal reservoir seems to have been two species, chickens and pigs, which were of Old World origin.}

Two species of HIV infect humans: HIV-1 and HIV-2. HIV-1 is more virulent and more easily transmitted. HIV-1 is the source of the majority of HIV infections throughout the world, while HIV-2 is less easily transmitted and is largely confined to West Africa. [1]

Both species of the virus (HIV-1 and HIV-2) are believed to have originated in West-Central Africa and jumped species (zoonosis) from primates to humans. HIV-1 evolved from a Simian Immunodeficiency Virus (SIVcpz) found in the chimpanzee subspecies Pan troglodytes troglodytes. [2] DNA sequencing indicates that HIV-1 (group M) entered the human population in the early 20th century, probably sometime between 1915 and 1941. [3][4] HIV-2 crossed species from a different strain of SIV, this one found in sooty mangabeys (an Old World monkey) of Guinea-Bissau. [5]

SIVs in non-human primates tend to cause non-fatal disease. Comparison of the gene sequence of SIV with HIV should therefore give us information about the factors necessary to cause disease in humans. The factors that determine the virulence of HIV as compared to most SIVs are only now being elucidated. Non-human SIVs contain a nef gene that down-regulates CD3, CD4, and MHC class I expression; most non-human SIV's therefore do not induce immunodeficiency; the HIV nef gene however has lost its ability to down-regulate CD3, which results in the immune activation and apoptosis that is characteristic of chronic HIV infection.[6]

Identification of the virus
In May 1983, doctors from Dr. Luc Montagnier's team at the Pasteur Institute in France, reported that they had isolated a new retrovirus from lymphoid ganglions that they believed was the cause of AIDS.[27] 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 National Cancer Institute (NCI).[28] In May 1984, Dr Robert Gallo of the NCI also isolated a virus that caused AIDS, and named it Human T-cell Lymphotropic Virus-III (HTLV-III).[29] 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, from the same source, and was the etiological agent of AIDS.[30][31] In May 1986, the International Committee on the Taxonomy of Viruses ruled that both names should be dropped and a new name, HIV (Human Immunodeficiency Virus), be used.
