HIV origin 'found in wild chimps' If this is true?

I heard that on the radio today.  As I recall, a team of researchers in Gabon found this particualar strain of HIV in chimp droppings out in the bush.  Imagine going to West Africa to study chimp droppings.

It is extremely unlikely.  The reason is because Mosquitos are are not part of the HIV life cycle.  In order for a person to actually be infected, the Mosquito would have to first take blood from an infected individual (who is at the stage when enough HIV particles are present in blood) and it would then have to get into the Mosquito's saliva and survive until the Mosquito went to bite another individual.  Again extremely unlikely.

(m)\n\nThe origin of AIDS and HIV has puzzled scientists ever since the illness first came to light in the early 1980s. For over twenty years it has been the subject of fierce debate and the cause of countless arguments, with everything from a promiscuous flight attendant to a suspect vaccine programme being blamed. So what it the truth? Just where did AIDS come from?\n\nThe first recognised cases of AIDS occurred in the USA in the early 1980s (more about this period can be found on our history page). A number of gay men in New York and San Francisco suddenly began to develop rare opportunistic infections and cancers that seemed stubbornly resistant to any treatment. At this time, AIDS did not yet have a name, but it quickly became obvious that all the men were suffering from a common syndrome. The discovery of HIV, the Human Immunodeficiency Virus that causes AIDS was made soon after. While some were initially resistant to the connection (and indeed remain so today), there is now clear evidence to prove that HIV does cause AIDS. So, in order to find the source of AIDS, it is necessary to look for the origin of HIV, and find out How, When and Where HIV first began to cause disease in humans.

Did really humans?  chimpanges?  I have not a clue.\n\nI would suggest, you may have evolved from under a rock.\n\n.

Hi.  I just did a google search on the origin of Aids and Hiv....\nI remembered something about it starting in Africa, but the link I am sending you will tell you the whole story and the dates.\nHope I was of some help...\n\n~Linda S~\naka\nlongleggedblonde1378

No. Humans and chimps are entirely reproductively isolated. Mating will not produce any kind of hybrid.

1.HIV/AIDS looks to be prominent among the gay community probably becoz this virus and the disease was first discovered in gays and was thought to infect only the gays,thus it was termed as a gay related disease but it is well know now that even hetrosexuals can get it if u sleep around with people without any protection.\n2.How we humans got it remains a mystery but scientists now belive that we got it from their bite or when man consumed bush meat.\n3.No America was not the first place,it just that this disease was first discoved in America in 1980's.It was know to have existed in Africa even earlier in the 1950's.

hahahayhhahaha.\n\nthe gay monkeys did not 'evolute' in to straight right wing bible thumpers.\n\nactually homosexuality is very common in the animal kingdom\n\nMale big horn sheep live in what are often called "homosexual societies." They bond through genital licking and anal intercourse, which often ends in ejaculation. If a male sheep chooses to not have gay sex, it becomes a social outcast. Ironically, scientists call such straight-laced males "effeminate."\n\nGiraffes have all-male orgies. So do bottlenose dolphins, killer whales, gray whales, and West Indian manatees. Japanese macaques, on the other hand, are ardent lesbians; the females enthusiastically mount each other. Bonobos, one of our closest primate relatives, are similar, except that their lesbian sexual encounters occur every two hours. Male bonobos engage in "penis fencing," which leads, surprisingly enough, to ejaculation. They also give each other genital massages.

No, Chimpanzees have different blood types, as do Monkeys of different species, as do Horses, as do Lions, as do many other animals.  It has something to do with workings of the immune system I think.

*Pondering awhile* The official date for the beginning of the AIDS epidemic is marked as June 18, 1981, when the U.S. Center for Disease Control and Prevention reported a cluster of Pneumocystis carinii pneumonia (now classified as Pneumocystis jiroveci pneumonia) in five gay men in Los Angeles. Originally dubbed GRID, or Gay-Related Immune Deficiency, health authorities soon realized that nearly half of the people identified with the syndrome were not gay. In 1982, the CDC introduced the term AIDS to describe the newly recognized syndrome.\nThree of the earliest known instances of HIV infection are as follows:\n   1. A plasma sample taken in 1959 from an adult male living in what is now the Democratic Republic of Congo.\n   2. HIV found in tissue samples from an American teenager who died in St. Louis in 1969.\n   3. HIV found in tissue samples from a Norwegian sailor who died around 1976.\nTwo 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 HIV-1 and HIV-2 are of primate origin. The origin of HIV-1 is the Central Common Chimpanzee (Pan troglodytes troglodytes). The origin of HIV-2 has been established to be the Sooty Mangabey (Cercocebus atys), an Old World monkey of Guinea Bissau, Gabon, and Cameroon.\n\nOne currently controversial possibility for the origin of HIV/AIDS was discussed in a 1992 Rolling Stone magazine article by freelance journalist Tom Curtis. He put forward the theory that AIDS was inadvertantly caused in the late 1950's in the Belgian Congo by Hilary Koprowski's research into a polio vaccine. Although subsequently retracted due to libel issues surrounding its claims, the Rolling Stone article encouraged another freelance journalist, Edward Hooper, to travel to Africa for 7 years of research into this subject. Hooper's research resulted in his publishing a 1999 book, The River, in which he alleged that an experimental oral polio vaccine prepared using chimpanzee kidney tissue was the route through which SIV mutated into HIV and started the human AIDS epidemic, some time between 1957 to 1959.\nFor quite a bit more see http://en.wikipedia.org/wiki/Aids#Origin_of_HIV.2FAIDS

Lots of STDs have been around passed from person to person for thousands of years, like syphillis.\n\nSome STDs (and other diseases, like the plague) may come from animals...sort of. But not from sex with animals as people like to say.\n\nAIDs is thought to have originated as a primate disease (i.e. monkeys) but it wasn't fatal to the primates. At some point humans ate primate meat or were exposed to their blood or saliva (through a monkey bite, or butchering them, for example), and were exposed to the virus which later mutated to become a human disease.

Simian immunodeficiency virus (SIV) is a retrovirus that is found, in numerous strains, in primates; the strains infecting humans are HIV-1 and HIV-2, the viruses that cause AIDS\n\nHuman immunodeficiency virus (commonly known as HIV, and formerly known as HTLV-III and lymphadenopathy-associated virus) is a retrovirus that is the cause of the disease known as AIDS, or Acquired Immunodeficiency Syndrome, a syndrome where the immune system begins to fail, leading to many life-threatening opportunistic infections.

No one has ever conclusively shown that any HIV infection was spread by mosquito bite.\n\nIt is believed that the virus is unable to survive in the mosquito as the insect is cold-blooded, and the environmental temperature within the insect would fluctuate too much for HIV to survive (which is one reason that HIV is a blood borne disease, instead of being able to be spread by sneezing/coughing and the like).\n\nAlso, the mosquito injects anti-coagulant saliva into a wound through a hollow stylet known as the hypopharynx, but blood is drawn into the mosquito via the labrum/epipharynx - a totally separate hollow tube.  They do not inject blood back into their victim, making transfer by this method highly unlikely.\n\nThe only way that a mosquito could transfer infected blood from one victim to another would be if some blood were left on the maxillae or mandibles that they use to pierce their victim's skin, and they moved to another victim and transfered that blood before the virus expired.  The amount of blood transferred in this fashion would be minute (perhaps a few cells at the most), and it would need to be done soon after the first feeding or the virus would die.\n\nWhen you consider the number of mosquito bites per person in somewhere like sub-Saharan Africa, and the infection rates of people positive for HIV in that region, even something as unlikely as a mosquito transferred case of HIV cannot be completely and totally ruled out.  It might have happened once or twice.  There's no way to know for sure.\n\nIt is exceedingly unlikely though.

Start by reading the texts.  We did not descend from chimps.  We evolved from a common ancestor.\n\nWe share more DNA with Bonobo Chimps than we do with Neanderthal.\n\nLooking for predictions is interesting but not likely to be helpful.  First the rate of genetic mutation in DNA is known. \n\nSecond, there is no telling what evolutionary pressures will cause an expression of a gene to reflect a mutation ahead of the event.\n\nThird, given all of the mutagenic chemicals used in so many facets of production and general living, it is hard to make the prediction you ask for.\n\nConsider these: \n\nIn fewer than 70 years our ability to use penicillin and many of the early antibiotics is severely diminished.  in fact there are strains of bacteria that are completely resistant to some antibiotics (i.e: vancomycin resistant enterococus = VRE). As people improperly use antibiotics, new and hardier strains of bacteria emerge.\n\nThe thre most devistating epidemics in human history were variation of the inlfuenza.  The first is the Spanish Flu of 1918 which killed more people in 18 months than WWI, or (24 years of AIDS).  Here is what the WHO says about all three (Spanish Flu, Asian Flu, and Hong Kong Flu).\n\nPandemic influenza\n\nThree times in the last century, the influenza A viruses have undergone major genetic changes mainly in their H-component, resulting in global pandemics and large tolls in terms of both disease and deaths. The most infamous pandemic was “Spanish Flu” which affected large parts of the world population and is thought to have killed at least 40 million people in 1918-1919. More recently, two other influenza A pandemics occurred in 1957 (“Asian influenza”) and 1968 (“Hong Kong influenza”) and caused significant morbidity and mortality globally. In contrast to current influenza epidemics, these pandemics were associated with severe outcomes also among healthy younger persons, albeit not on such a dramatic scale as the “Spanish flu” where the death rate was highest among healthy young adults.\n\nMost recently, limited outbreaks of a new influenza subtype A(H5N1) directly transmitted from birds to humans have occurred in Hong Kong Special Administrative Region of China in 1997 and 2003.

It is theoretically possible, yes.  However, there have been *NO* confirmed cases of HIV transmission through oral sex and the risk of this type of transmission is very, very low.
