How did AIDS originate?????

Question

Where did it come from?? How did evolve??

Answer 1

It emerged from monkeys, where it was less pathogenic, and it's beleived to have passed the species barrier during hunting; HIV is a blood bourne virus, and putting an open wound/cut in contact with a bloody monkey corpse would easily allow transmission.

It's unlikely to have passed through beastalic anal penetration with monkeys; althrough I will admit that's a more interesting-and therfore prominent-theroy.

As for the transmission through eating an infected monkey: that's even more unlikely-if not impossible. HIV is not adapted, in anyway, to bind and penetrate the muccosal lining of the digestive system. The digestive sytem also employs a couple of defensive sytems to defend against pathogenic bacteria/virus'. For instance, the acidity of the stomach may destroy the viral envelope and capsid coat. The ways in which HIV can infect are well documented, and no instances-amonst the millions- where the person was infected orally have been found.

Once the HIV virus had passed the monkey-human barrier, its initial spread-through the human population- was most likely caused by sexual promiscurity of those hunters.

The virus has, most likely, been present in monkeys for hundreds of years. It probably crossed the monkey/human barrier a couple of times. In the past, however, the virus did'nt spread amognst humans because of differences in: sexual activity, travelling and intravenous injection.

Answer 2

It is very much like Simian (primates like Chimpanzees) Immuno Deficiency Syndrome. Some various reports like to trace the origins of HIV to chimps in Africa. While some perceive that some drunken idiot had sex with chimps, it is more likely that the virus crossed species in such activites as capturing a chimp, butchering a chimp for meat or biological sample parts, or eating a chimp's parts that were not cooked, or at least not fully cooked.

As for how it evolved, that is the 64 million dollar question, it is constantly evolving. With each person there is a possibility of some uniqueness that will develop so that when that person infects another that virus will be discernably different from the one the previous party caught. Sometimes there are virtual pedigrees for the disease. I've been following some of the drug companies that study it, even smaller firms like Vaxgen (whom I still believe was on track before the political correctness crowd got mad at them). They almost all report how hard it is to attack or vaccinate against the HIV/AIDs disease because of its ellusive qualities (it can hide for months or years) and the evolving nature of the bug. About the time they figure something that doesn't change and design something to attack that fixed target, they will find in other test subjects it has changed after all. It is a pretty virulent bug.

Answer 3

A silent heterosexual epidemic occurred and spread via travelers to industrialized nations of Europe and North America, where the new syndrome was initially recognized as a distinct clinical entity in 1981, even though the number of cases then was minuscule. By 1983, epidemiologists had discerned the routes of transmission and pointed the way for laboratory investigators to identify the etiologic agents. In 1984, the laboratory culturing of HIV was described in the scientific literature, as was the first serologic test for detecting the HIV antibody, which has been used to screen blood donations since 1985. Originally given three different names by the French (1983) and two American (1984) research teams that "discovered" the virus, the name HIV was agreed upon in 1986.

Answer 4

From what I understand, it started in Africa and was disease carried by monkeys.
People who were in close contact with the monkeys contracted the disease and thus carried it and gave it to others and it spread from one person to another. At the time they didn't know what AIDS was and how to treat it.
I grew to great proportions and people carried the virus to other counties like America Where through homosexual contact it grew and grew until it became a threatening disease and doctors finally found out what it was and how it was spread. It has been spreading from Gay and drug needle uses to heterosexuals. In the early days it was a sentence of death, but now with new drugs it's been able to be contain in many cases, but it is still rapid due to ignorance and misunderstanding that it is still a dangerous disease and kills millions of people each year.

Answer 5

Signs of pre-AIDS exist among species of monkey's found in Africa. It is believed it began effecting humans following a 'jungle clearing' practice of African Tribes where they would light fires in the jungles and kill all the escaping animals and eat them. This includes monkeys and other primates. The blood exposure and the HIV virus MAY have found a way to survive in humans and create the AIDS epidemic we see today.

Had to do a project in an Anthropology class in College on the subject, i don't have exact names for the Primate version of the virus, and it's not for certain, but it is a theory, and it does exist in African Primates.

Answer 6

The same way S.A.R.S. did. From exposure to a dangerously open sewage source. The human colon is the bodys' sewage elimination system. It's also interjected that space born viruses have been known to come to earth. How this is possible in a vacuum I'm not clear but it would be worth your while to do a follow up on SARS and all pertinent data from a news archive source here on Yahoo.

Answer 7

We know that chimpanzees, which are not monkeys but apes, carry the AIDS virus. I can't imagine any other way for the virus to have been given to humans other than bloody surfaces that were unfortunately shared by ape and human.

Answer 8

some stupid guy went out and screwed a monkey. I'm not even kidding. It was a primate disease, then mutated in the guy and became a human disease. Stupid ppl, at least keep it in the species..cause thats a pretty retarded way to start such a bad virus

Answer 9

the green monkey in africa, someone either screwd the monkey or somehow, they got the aids from the monkey then came to america. the first identified case of aids was in 1981

Answer 10

From Africa..the natives ate monkey...aids virus is prevelant in monkeys...if the meat isnt cooked thoroughly, then the virus can be transmitted....
