How did the very first person got AIDS ? |
Its said that aids spread through many ways and it does not come on its own to anyone ... ( though a baby may get fm his/her mother ) then how did the very first person got aids ? how did that HIV virus became infective? did that come fm monkeys ?? There is extremely convincing data that HIV originated from similar viruses (simian immunodeficiency virus....of which there are different strains in different primates) endemic to certain type of African primates (at least two different types as shown by NUMEROUS studies.) By most accounts, the cross-species transmission occured virtually simultaneously and in widely separate locations in Africa. The exact timing of their human introduction has not been established conclusively. Some models suggest it was sometime in the past few hundred years, some models suggest as recently as the early 1950s. In Africa, especially in areas surrounded by jungle, monkeys are a source of food and are hunted. It is very possible that a mutated form of SIV jumped to humans when the meat was being butchered or eaten. Human-monkey sex is not likely, but is often referenced as way to stigmatize/dehumanize HIV, Africans, and those living with HIV. For cross species transmissions (zoonotic infections) a variety of things need to occur, and it is very likely that a mutated form of SIV jumped into humans many times over the years but were unable to become infectious from human to human, or died out when the person they infected dies....average number of sexual partners was a lot lower. Just like with " Bird Flu" epidemic. The bird flu has to mutate from the form in birds and other related animals, to a a form that is infectious to humans (which it has) and secondly needs to mutate again to become able to easily transmit from human to human..... possible pandemic. HIV replicates so fast (10 billion new viruses daily in an untreated human) and it SUCKS at reproducing exact copies of itself....it can have many mutations that produce stronger, weaker viruses, or viruses immune to the medicines we have. It mutates faster than the common cold virus. So mutations can occur quickly. Hope this helps Source(s): I can provide the full list of studies referred to here if anyone wants....but it's a lot of typing and I'm tired :) green monkey/ in/ Africa I'm almost positive monkeys were involved. Just wikipedia it, or look at the national website for the disease, I'm sure it's there :) a man had sex with a monkey.... dont ask me how the monkey got it. I believed that the Moneys tranferred HIV virus to people. Although there are many stories/guesses of how and from where the disease originated? HIV virus is strongly believed to be originated from Africa around 1940. According to stored records, the first known patient of AIDS disease was from one of the states of Africa in 1959 whose blood was stored in order to find out the possible cause of his death. In tests carried out, the blood is confirmed to contain AIDS virus. It is believed that the HIV virus inherits its properties from a virus SIV (Simian Immunodeficiency Virus), which is found in monkeys. The AIDS virus also has developed its own characteristics along with those which it inherits from SIV. The SIV virus has exactly same genetic structure as that of HIV and both the viruses are transmitted same way from one host to another. The SIV virus causes AIDS in monkeys and has exactly same effects on them but it does not show any such effect on humans, whereas HIV causes AIDS in humans but not in monkeys. There are again many interesting stories/guesses/hypothesis as how the HIV virus born from the SIV virus? And how SIV virus got mixed in the human blood? |
