How do you think the HIV virus travelled from a Chimp to human?

Question

Is it a case of a desparate man making it out with a chimp????

Answer 1

Ya it did thro the sexual intercourse with a chimp in some african jungles where men n chimps are no different.

Answer 2

There is a book out (don't know the title). As best I can remember, back in the 40's when polio vaccine was being created and tested, one scientist in the Belgian Congo was using chimpanzees instead of monkeys to grow the polio antibody. They are not supposed to use chimps because they are too closely related to humans. Since chimps have an aids-type virus, this mutated along with the polio virus. When the serum was produced and given to people, the human aids virus began. Since aids supposedly started in this area, this explanation makes sense to me. Especially since the chimps have had aids for millenia and humans have never caught it before.

Answer 3

Nope. I read a huge, detailed book (The River) and I think I can shorten the 2,500 some odd pages. When polio hit the world, one of the best places to grow the polio vaccine was on a chimpanzee's liver. They caught chimps in Africa by the thousands to grow this culture, and of course, in dealing with wild animals, some got bitten. Others were exposed to blood in the course of killing these animals or handling their organs after death. But some of these chimps had SIV, or the simian version of HIV. The disease crossed species, and voila... an epidemic has begun. The men who, of course, did not know that they had been contaminated with anything, went on to have sexual partners, and they think there was a young man who was an airline steward who brought it to the United States sometime in the mid 1950's.

Answer 4

Once HIV enters the body, the body starts to produce antibodies—substances the immune system creates after infection. It can take some time for the immune system to produce enough antibodies for the antibody test to detect, and this time period can vary from person to person. Commonly referred to as the “window period.” Most people will develop detectable antibodies within 2 to 8 weeks (the average is 25 days). Even so, there is a chance that some individuals will take longer to develop detectable antibodies. Another type of test is an RNA test, which detects the HIV virus directly. The time between HIV infection and RNA detection is 9–11 days.

Answer 5

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.

If a cross species jump is indeed the origin of HIV then the following conditions would most likely be required:

1. a large human population,
2. a large nearby population of a host animal,
3. a pathogen that eventually mutates to spread from animal to human,
4. interaction between the species to transmit enough of it to humans to establish a human foothold, which may take millions of individual exposures,
5. a mutation of same pathogen that can spread from human to human,
6. some method that allows the pathogen to disperse widely so it does not "burn out" in a local population of humans.

Such requirements existed in the remote past with smallpox, and also with the 20th century Spanish Flu.

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.

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. DNA sequencing indicates that HIV-1 (group M) entered the human population in the early 20th century, probably sometime between 1915 and 1941. HIV-2 crossed species from a different strain of SIV, this one found in sooty mangabeys (an Old World monkey) of Guinea-Bissau.

Answer 6

I think it developed into a human catastrophe when one person may have simply been bitten by a chimp and not realizing they carried HIV. They probably neglected to been seen by a doctor and they ultimately passed HIV onto their loved ones or whomever they came into sexual contact with or one of their drug partners. And this just opened the door for the domino effect on millions and millions of people all over the world.

Answer 7

It was made in a laboratory and injected into a chimp and when that chimp was ready to retire and they let him go in Africa, well humans do mate with monkeys there and it was either transmitted that way or by blood exchange with a monkey.

Or it was governments way of controlling the population.

Answer 8

it was most likely a lab chimp and some how the blood was transfered to a sciantist. this is my theory. cause you know the chimp could of bit him or something and the blood could have passed through.

Answer 9

Humans were having sex with the Chimps, than started spreading to humans.

Answer 10

Some tribes in Africa used to eat chimps, some still do that today. Probably this is how it has happened.

Answer 11

it sounds to me like someone is useing the chimps to run studys on hiv and i think thats wrong
