how did the aids'virus spread from green monkey's in africa to human's?
154438
I heard it came from some natives engaging in sexual contact with the monkeys, getting infected with the virus and passing it on to a human partner.I have absolutely no refference material for this speculation tho, it's something i heard a long time ago.

Acquired Immune Deficiency Syndrome (AIDS or Aids) is a collection of symptoms and infections in humans resulting from the specific damage to the immune system caused by the human immunodeficiency virus (HIV).[1] The late stage of the condition leaves individuals prone to opportunistic infections and tumors. Although treatments for AIDS and HIV exist to slow the virus's progression, there is no known cure. HIV is transmitted through direct contact of a mucous membrane or the bloodstream with a bodily fluid containing HIV, such as blood, semen, vaginal fluid, preseminal fluid, and breast milk.[2][3] This transmission can come in the form of anal, vaginal or oral sex, blood transfusion, contaminated hypodermic needles, exchange between mother and baby during pregnancy, childbirth, or breastfeeding, or other exposure to one of the above bodily fluids.\n\nMost researchers believe that HIV originated in sub-Saharan Africa during the twentieth century;[4] it is now a pandemic, with an estimated 38.6 million people now living with the disease worldwide.[5] As of January 2006, the Joint United Nations Programme on HIV/AIDS (UNAIDS) and the World Health Organization (WHO) estimate that AIDS has killed more than 25 million people since it was first recognized on June 5, 1981, making it one of the most destructive epidemics in recorded history. In 2005 alone, AIDS claimed an estimated 2.4–3.3 million lives, of which more than 570,000 were children.[5] A third of these deaths are occurring in sub-Saharan Africa, retarding economic growth and destroying human capital. Antiretroviral treatment reduces both the mortality and the morbidity of HIV infection, but routine access to antiretroviral medication is not available in all countries.[6] HIV/AIDS stigma is more severe than that associated with other life-threatening conditions and extends beyond the disease itself to providers and even volunteers involved with the care of people living with HIV.\n\nTAKE CARE AND GOOD LUCK !

There is a great article on this...web address is below.  Explains that the HIV virus first developed in monkeys, transferred to chimps, them to men who hunted and ate the chimps.  Read it...very interesting.

I don't know if the % is that high but many articles tell you that it is easier to transmit aids through anal intercourse, hence gays have a higher %\n\nThis articles says\n"Transmission through anal sex has been reported to be 10 times higher than by vaginal sex."\n\nThis holds true with heterosexuals who have anal intercourse with women as a form of controception. This is another reason why it is spreading so fast in africa.

That's not true.\n\nHIV 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.\n\nIf a cross species jump is indeed the origin of HIV then the following conditions would most likely be required:\na large human population,\na large nearby population of a host animal,\na pathogen that eventually mutates to spread from animal to human,\ninteraction between the species to transmit enough of it to humans to establish a human foothold, which may take millions of individual exposures,\na mutation of same pathogen that can spread from human to human,\nsome method that allows the pathogen to disperse widely so it does not "burn out" in a local population of humans.\n\nSuch requirements existed in the remote past with smallpox, and also with the 20th century Spanish Flu.\n\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.\n\nBoth 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.

They think it began in Africa among animals and spread to the humans who ate those animals.  It is spread through bodily fluids--blood transfusions, sexual intercourse and intravenous drug use are the most common ways it is spread.

How is HIV Transmitted?      \n\nHIV can be transmitted from an infected person to another through:\n\nBlood (including menstrual blood) \nSemen \nVaginal secretions \nBreast milk \nBlood contains the highest concentration of the virus, followed by semen, followed by vaginal fluids, followed by breast milk.\n\n* Activities That Allow HIV Transmission\n\nUnprotected sexual contact \nDirect blood contact, including injection drug needles, blood transfusions, accidents in health care settings or certain blood products \nMother to baby (before or during birth, or through breast milk) \nSexual intercourse (vaginal and anal): In the genitals and the rectum, HIV may infect the mucous membranes directly or enter through cuts and sores caused during intercourse (many of which would be unnoticed). Vaginal and anal intercourse is a high-risk practice.\n\nOral sex (mouth-penis, mouth-vagina): The mouth is an inhospitable environment for HIV (in semen, vaginal fluid or blood), meaning the risk of HIV transmission through the throat, gums, and oral membranes is lower than through vaginal or anal membranes. There are however, documented cases where HIV was transmitted orally, so we can't say that getting HIV-infected semen, vaginal fluid or blood in the mouth is without risk. However, oral sex is considered a low risk practice.\n\nSharing injection needles: An injection needle can pass blood directly from one person's bloodstream to another. It is a very efficient way to transmit a blood-borne virus. Sharing needles is considered a high-risk practice.\n\nMother to Child: It is possible for an HIV-infected mother to pass the virus directly before or during birth, or through breast milk. Breast milk contains HIV, and while small amounts of breast milk do not pose significant threat of infection to adults, it is a viable means of transmission to infants.\n\nThe following "bodily fluids" are NOT infectious:\n\nSaliva \nTears \nSweat \nFeces \nUrine

People believe that HIV virus first originated from Africa.\nIn 1982 HIV virus was defined the first time in USA community.\nTwo men ( homo sexual ) were captured and brought to the hospital with strange symptom.\nA  scientist had done many research project to find out the role of this virus. \nHe drew the conclusion that virus HIV causes AIDS decease including some distinctive symptom

Actually the virus has its origins in Africa. In the 1950s when the African government with the aid of the united nations began vaccinations for polio. HIV was introduced to the people in the vaccine. The polio vaccine was grown using Rhesus and Simian monkey which has a very similar viral infection. In fact they are cousins or genetically related. The vaccines for polio were contaminated with the HIV virus. There is a good book that talks about this occurrence called "The River". It was titled this because it was along this route that the virus spread and the polio vaccine was implemented. This may be a coincidence but some people think it was done on purpose. I think it was a medical mistake.

Science pretty much backs up the theory that HIV evolved from SIV (Simian Immunodeficiency virus.)  SIV has been present in the ape population for probably thousands or millions of years.  \n\nSomeone may have become infected through a blood transfer - either by a bite, or by preparing a chimp for food.\n\nThe virus probably hung around in the human population for several years to maybe hundreds of years until it mutated into what we now know as HIV.  A virus is a great mutater and evolver.\n\nImmunodefiecency viruses are common in animals - there is FIV (feline), Bovine (cows,) etc.  None of them are transmittable to humans and HIV is not transferrable to them.  Because humans and apes are so similar, it makes sense that a virus that affects them would eventually be able to mutate into something that could infect us.\n\nThe idea that it was transferred by people having sex with chimps is ridiculous.

In short, there has never been a documented case of a mosquito trans-\nmitting the AIDS virus.  The virus cannot live inside a mosquito's \ngut, and even if it did, the mosquito does not ingest enough virus \nparticles when it feeds to pose any substantial threat of transmission.

There are many theories about the origin of the HIV virus but none of them have them proved.\n\n\nNo record of HIV virus exists in history and it has been said that it started in central Africa and from there it started spreading slowly and slowly.\n\n\nHIV was identified in 1983.Earlier the researchers found that chimps acquired the disease from eating one of their favorite preys: monkeys.\n\n\n“Chimps are 98 percent genetically the same as humans, and they don’t get sick from SIV. This is an especially important clue for developing an HIV vaccine, the researchers said. Understanding what prevents chimps from getting sick would help scientists duplicate resistance to AIDS symptoms in humans.”\n\n\nResearchers say, “Chimps likely picked up viruses from both types of monkeys, and eventually a hybrid formed, the researchers said. That probably happened tens of thousands of years ago, which may have given chimps an opportunity to evolve resistance to an AIDS-like disease.”\n\n\nSome researchers say that virus related to HIV is found in monkeys in Africa. Many scientists believe that the first humans got the HIV virus from monkeys by eating them as food or being scratched or bitten by them. It is possible that during preparation of the food or butchering the meat the infected blood could have entered the human body through a cut.\n\n\nA Canadian flight attendant, nicknamed “patient zero” dies of AIDS he had sexual connection with several of the first victims of AIDS. It is believed that he is responsible for introducing the virus into the general population. By 1984 there are almost 8000 confirmed cases in the US, with 3700 confirmed deaths (CDC surveillance report, Dec. 1984).

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

i really have no idea where it came from. for some reasons monkeys come to mind. i think they were carriers and some human got it and then it just kindof spread from there. it took a while to become mainstream.
