how did aids started?

*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

im not sure .. but if you look into aids you come up with some interesting things that seem to be supported by some pretty convincing evidence ... in a nutshell they say aids was started through vaccines in africa and select groups of people in the US.

Dr. David Ho and colleagues from the Aaron Diamond AIDS Research Center in New York told a conference they traced the very first case of HIV infection to a man, David Carr, living in what was then the Belgian Congo in 1959.   \n\nThese scientists believe the HIV virus crossed over from ape polulations to humans in the late 40's or early 50's based on the fact that it must have been present for that long in order for someone to be sick with AIDS in 1959.  Other early HIV infections are the following:\nHIV found in tissue samples from an American teenager who died in St. Louis in 1969. \nMost scientists estimate that the disease developed in Africa around 1930.\nHIV found in tissue samples from a Norwegian sailor who died around 1976.\n\nThere is another interesting theory out there with some intriguing evidence is that HIV was accidentally introduced to Africa through administration of polio vaccine that was contaminated with HIV from the chimpanzee organs used to make the polio vaccine.  This is a VERY controversial theory since it implies that Western Medicine gave AIDS to Africa.  Here's a summary of the evidence:Overview of the theory\nOne theory of the origin of AIDS is that it developed from contaminated vaccines used in the world's first mass immunisation for polio. There are a number of reasons why this theory is plausible enough to be worthy of further investigation.\n\nThe location coincides dramatically. The earliest known cases of AIDS occurred in central Africa, in the same regions where Koprowski's polio vaccine was given to over a million people in 1957-1960. \nThe timing coincides. There is no documented case of HIV infection or AIDS before 1959. Centuries of the slave trade and European exploitation of Africa exposed Africans and others to all other diseases then known; it is implausible that HIV could have been present and spreading in Africa without being recognised. \nPolio vaccines are grown (cultured) on monkey kidneys which could have been contaminated by SIVs. Polio vaccines could not be screened for SIV contamination before 1985. \nAnother monkey virus, SV-40, is known to have been passed to humans through polio vaccines. A specific pool of Koprowski's vaccine was later shown to have been contaminated by an unknown virus. \nIn order for a virus to infect a different species, it is helpful to reduce the resistance of the new host's immune system. Koprowski's polio vaccine was given to many children less than one month old, before their immune systems were fully developed. Indeed, in one trial, infants were given 15 times the standard dose in order to ensure effective immunisation. \n\nIf this theory is correct, it has serious ethical, health and policy implications. In particular, it points to the danger of interspecies transfer of material through vaccinations, organ transplants, etc., which could lead to new variants of AIDS as well as other new diseases. As well, studying the theory may lead to insights about responding to AIDS and preventing new diseases.\n\nHowever, there has been no sustained attempt to test the theory. This could be done, for example, by testing stocks of polio vaccine for the presence of SIV. An offer to undertake tests was made as early as 1991; only in 2000 were some samples tested, and then only US-made vaccine. Another possibility would be to test stored blood samples in Africa from before 1950. If HIV is found, this would undermine the theory.\n\nThere was a documentary made that details this theory too called "The Origin of AIDS" by Peter Chappell

A lot of scientists theorize that HIV first originated from chimpanzees and were transferred on at least three seperate occasions from chimpanzees to humans in Africa. They also say that chimpanzees have carried HIV for hundreds of thousands of years before, but do not show any symptoms. In other words, it doesn't affect them.\n\nSome scientists say that humans were first exposed to the virus in Africa, when bush-meat hunters slaughtered a chimpanzee and ate it. A lot of people in Africa still hunt chimpanzees for consumption; they kill so many of them that the number of wild chimpanzees in Central Africa is dwindling.\n\nBecause of speculation that the chimpanzees first had HIV before humans did, a lot of scientists are testing monkeys and wild chimpanzees to see if they can figure out why the virus doesn't harm the monkeys and possibly find a cure for HIV/AIDS from there.

This question is ridiculous. AIDS is not only an epidemic, it is a pandemic, and it is most certainly something to be scared of.\n\nThe HIV/AIDS virus is only transmissable through bodily fluids; blood and semen. For this reason, it is most commonly found in gay men and drug abusers. Gay men have anal sex, which usually results in some anal bleeding. When one man ejaculates, the semen can infect the open wounds from which the blood is emitting. This however, it not only seen in gay men, it is also a risk to women who have anal sex with an infected male. Transmission is no different.\n\nIn terms of transmission among drug abusers, this refers to drugs such as heroine which is taken with a needle. Drug abusers arent known for their cleanliness in this matter and  usually use needles which have already been used before. When the needle is used to inject someone with AIDS, it picks up the virus from their blood, when this needle is reused, the person who injects themself will most probably recieve the disease by introducing the infected blood of the first person into their own body.\n\nNo self respecting scientist...or educated person for that matter...would deny that AIDS is caused by a virus. It is a retrovirus and has been extensively studied. It cannot target any specific group of people. Those people are just more susceptible to it through unprotected anal sex and drug abuse with needles.\n\nIt is also very common for people who had blood transfusions in the late 70's and early 80's to have contracted the virus. This is because at that time there were far less restrictions on who could or could not give blood; also, not enough was known about the virus to test blood donors for the disease.\n\nI'm sorry to tell you that the AIDS in africa is the same AIDS we have here, in fact, 50% of the South African army is infected with the HIV virus. There have been more deaths in Africa due to AIDS than there have been deaths by malaria. It is more common in africa due to their lack of contraception, and their significantly less sanitary and deprived medical centers.

"Human immunodeficiency virus (commonly known as HIV, and formerly known as HTLV-III and lymphadenopathy-associated virus) is a retrovirus that primarily infects vital components of the human immune system such as CD4+ T cells, macrophages and dendritic cells. It also directly and indirectly destroys CD4+ T cells. As CD4+ T cells are required for the proper functioning of the immune system, when enough CD4+ T cells have been destroyed by HIV, the immune system functions poorly, leading to the syndrome known as AIDS. HIV also directly attacks organs, such as the kidneys, the heart and the brain leading to acute renal failure, cardiomyopathy, dementia and encephalopathy. Many of the problems faced by people infected with HIV result from failure of the immune system to protect from opportunistic infections and cancers.\n\nHIV is transmitted through direct contact of a mucous membrane with a bodily fluid containing HIV, such as blood, semen, vaginal fluid, preseminal fluid or breast milk. This transmission can come in the form of: penetrative (anal or vaginal) sex; oral sex; blood transfusion; contaminated needles; exchange between mother and infant during pregnancy, childbirth, or breastfeeding; or other exposure to one of the above bodily fluids.\n\nHIV is hypothesized to have originated in southern Cameroon after jumping from wild chimpanzees (Pan troglodytes troglodytes) to humans during the twentieth century[1][2]. Infection in humans is now pandemic. 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 December 1, 1981, making it one of the most destructive pandemics in recorded history. In 2005 alone, AIDS claimed an estimated 2.4 - 3.3 million lives, of which more than 570,000 were children.[3] A third of these deaths are occurring in sub-Saharan Africa, retarding economic growth by destroying human capital. Current estimates say that about 28 million people have died and that HIV is set to infect 90 million people in Africa, resulting in a minimum estimate of 18 million orphans in Africa.[4] Antiretroviral treatment reduces both the mortality and the morbidity of HIV infection, but routine access to antiretroviral medication is not available in all countries.[5] 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."

Aids virus has been suggested that it is Biological warfare compound and that HIV is indeed attached to the Aids virus. \n\nThe reason it is so prevalent in Africa is that the peoples in Africa are very susceptible to parasites and other pathogens, so much so that their immune systems are compromised. It didn't originate there though.

Humans are the only known animals that can carry the human immunodeficiency virus (HIV), which causes AIDS.

it all started when God created the heavens and the earth.  He didnt want people to have sex between species so he made the aids virus.  well some genius in africa thought it would be fun to have sex with a monkey.  he got aids, then he went and spread it to others. now it is a Pandemic

Wow some of these answers are scaring me.\n\nAIDS is caused by a VIRUS - HIV - not by people.  \n\nWhoever it was that said its been around for a long time had it right - and we won't ever know for sure how and when it started.\n\nYes, it was first identified as a "gay man's disease," but obviously, or I thought obviously, we had moved beyond that.  \n\nAnd if its "punishment," then how do you explain babies becoming infected, and the people that were infected early on from blood transfusions, etc?\n\nCome on people.  Get logical here.\n\nViruses aren't punishments.  Viruses and bacteria don't take personal inventories of those they infect.  They just biologically do their thing, and that is to make people sick.  \n\nHIV isn't a punishment anymore than the common cold or the flu is.

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.

1959 Scientists isolate what is believed to be the earliest known case of AIDS. The discovery suggests that the multitude of global AIDS viruses all shared a common African ancestor within the past 40 to 50 years. \n  \n \n1978 Gay men in the US and Sweden -- and heterosexuals in Tanzania and Haiti -- begin showing signs of what will later be called  AIDS\n\n1980  Deaths in US -- 31 (includes all known cases 1981 and before)

The AIDS epidemic was discovered June 5, 1981, when the U.S. Centers for Disease Control and Prevention reported a cluster of Pneumocystis carinii pneumonia (now classified as Pneumocystis jiroveci pneumonia) in five homosexual men in Los Angeles.[96] Originally dubbed GRID, or Gay-Related Immune Deficiency, health authorities soon realized that nearly half of the people identified with the syndrome were not homosexual men.
