Well, i don't know the exact year but i know it started sometime in the 1980's

1981: The Beginning In 1981, the first cases of AIDS (Acquired Immune Deficiency Syndrome) were identified among gay men in the United States, acquiring the designation, GRID (Gay-Related By the end of 2003, twelve million children in Sub-Saharan Africa were orphaned by AIDS. Source: AVERT.ORG Image Source: CDC/Dr. Lyle Conrad Immune Deficiency); however, scientists later found evidence that the disease existed in the world for some years prior, i.e., subsequent analysis of a blood sample of a Bantu man, who died of an unidentified illness in the Belgian Congo in 1959, made him the first confirmed case of an HIV infection. Source: CNN In an article, "1959 and all that: Immunodeficiency viruses," by Simon Wain-Hobson of the Pasteur Institute in Nature (Volume 391, 5 February 1998, pp. 532-533), Wain-Hobson wrote: "Where did HIV [Human Immunodeficiency Virus] come from? Both of the AIDS viruses, HIV-1 and HIV-2, originated in Africa... As is often the case with microbes, a jump from one species to another is probably to blame... chimpanzees (for HIV-1) and sooty mangabeys (for HIV-2)... When did the AIDS epidemic begin?... the Big Bang seems to have occurred around, or just after, the Second World War. Emerging microbial infections often result from adaption to changing ecological niches and habitats." Cases of Pneumocystis carinii pneumonia (PCP, a lung infection) and Kaposi's sarcoma (a rare skin cancer) were reported by doctors in New York and Los Angeles in 1981, then the Centers for Disease Control and Prevention (CDC) began tracking a growing population of young men, women, and babies, whose immune systems were nearly destroyed. Late in 1982, the condition began to be referred to as AIDS. Source: American Red Cross For a few at first, their awareness of AIDS began with the publishing of a little noticed entry on page two of the CDC's Morbidity and Mortality Weekly Report of June 5, 1981, where a strange outbreak of killer pneumonia was spreading among gay men. Since this report, AIDS has graduated from a seemingly local phenomenon to a global epidemic. Source: CNN

No one really knows, considering how long it might have been going on quite a while before the 'official' medical community paid attention. But it was known by the mid 1980's.
4 :
The first recognized cases of AIDS where in the 1980's. Keep in mind that is just when it was recognized as a disease and not the year it originated.
5 :
it's firstly reported in 1981 in homosexual partner.
6 :
very late 70's or early 80's.
7 :
The early 80's why?

Since HIV/AIDS worldwide is primarily a HETEROSEXUAL disease, why do some insist on calling it a gay disease

Since HIV/AIDS worldwide is primarily a HETEROSEXUAL disease, why do some insist on calling it a gay disease?
I realize that in the US it was first detected in homosexuals, but it was already being passed between heterosexuals in numerous other countries and continues to be a disease that primary affects heterosexuals. To hear it called a "gay disease" makes one think that people with suspect agendas are trying to wrongfully inspire hatred and bigotry by associating the disease with a segment of the population they don't like or understand, don't you think?

Blah blah blah..... its not a hetero/homo disease..... its the worlds disease and problem... blah blah blah
2 :
your absolutely right. its all about trying to hate someone and target a particular group of people..mainly the GLBTIQ community.
3 :
many of the people that call it a gay disease, are also the ones who take three or four obscure verses from the bible and twist them to "prove" their claim that god hates gays.
4 :
Being a person living with HIV, and knowing many people with I would defiantly say it is a human disease, it now less of a problem in gay community now because we were hit the hardest at the beginning and we learned to take precautions, where as the ones who said it was a punishment from God thought that they wouldn't contact the disease and so they did not take the precautions and now its running rampant in the hetero community. So I guess God doesn't care who he punishes, what kind of God is that, not my God.

Aids is Acquired Immune Deficiency Syndrome. It starts out as HIV (Human immunodeficiency virus). There are thee stages to HIV. There are case where people have been in the HIV stages for over 10 years before AIDS took over. The person gets infected and it starts to destroy their immune system. Once it has taken a toll the immune system leaving it open to opportunistic diseases that wouldn't have the chance to infect a healthy person. Once it gets to aids it means the persons immune system has completely been destroyed. There is no vaccine because scientist haven't been able to find one yet. All their attempts have fallen through.
2 :
because it weakens ur immune system and t lymphocites which take up the vacinne
3 :
I'll answer your primar question why a vaccine has proved so difficult. HIV-1 and similar retrovirii, have a remarkable (a compliment to them, bad for us in a way) ability to change their genetic make-up. Making a vaccine means exposing an organism to the pathogen, and the organism produces antigens which then recognize the pathogen. These antigens are then harvested, purified and injected into susceptible persons. Though smallpox vaccine does not actually use smallpox virus to generate antigens, but rather a close relative variola, the method works. Not so with HIV, even if a close cousing were used, each copy of the HIV virus that is made in an infected individual millions upon millions at times, is different and would eventually conquer the protection afforded by a vaccine.

What my understanding of how vaccines work there are two main types. The first is where dead microbes are injected into a person, this then causes the bodies immune system to react and build an antibody for the microbe. Antibodies work on a simple level by making shapes which fit around the microbe, thus rendering it useless. For this to work, the antibodies in a person must be identical (and made for) the dangerous microbe which is likely to infect the person. As someone mentioned, unlike bacteria, viruses (because they are not living) have a genetic code which changes regularly. This is why a new flu vaccine is bought out each in the UK. This brings me onto the second type of vaccine. The second type is where a microbe almost identical to the dangerous one is administered to the patient, although often the bacteria or such has been genetically modified so that it is not harmful. However, the bodies immune system still reacts forms an anti-body. So how does this relate to HIV/AIDs? Well, because the viruses genetic material and "shape" is changing regularly it means most vaccines which use antibodies are deemed useless. This is the same reason viruses such as the common cold have no known cure, and although vaccines can be made by the time they are, the virus has often changed to radically for these antibodies to be effective. This doesn't however mean that there is no cure for HIV/AIDs, as it is likely with up coming nanotechnology a cure may be possible. A "vaccine" could be made by manufacturing nanobots which recognize and destroy the HIV virus. Another possible way of killing a virus is through the use of a magic bullet. Magic bullets are chemicals which can travel unnoticed through the body but have the ability to destroy microbes or bacteria. The first was discovered by Paul Ehrlich and was named Salversan 606 (or scientifically known as Arsphenamine) and had the ability to kill the syphilis microbe. So although medical science offers a possible cure for the disease in the future, it could be argued that all the money which is being invested into research for a cure the disease might be better spent buying condoms and offering education to the people in the countries suffering most heavily. Hope that answered your question, maybe a bit more thoroughly than needed but ow well, knowledge is power!
