HIV causes AIDS. At this stage, it is dangerous and negligent to suggest otherwise.
The claim that there are no "documents" that show HIV causes AIDS is simply mistaken.
Here are some documents that do demonstrate that, or that, in turn, list the evidence that HIV causes AIDS.
Numerous studies of HIV-infected people have shown that high levels of infectious HIV, viral antigens, and HIV nucleic acids (DNA and RNA) in the body predict immune system deterioration and an increased risk for developing AIDS. Conversely, patients with low levels of virus have a much lower risk of developing AIDS.
It is AVERT's considered opinion that the evidence that HIV causes AIDS is abundant and conclusive. This page outlines some of that evidence, while also mentioning how some dissidents have interpreted things differently.
Other indirect evidence that HIV was the cause of AIDS came from the demonstration, in 1984, of its high degree of tropism for the subgroup of CD4+ T cells, its consistent isolation from patients of different origins who had AIDS, and the isolation of similar viruses that cause AIDS in nonhuman primates (specifically, macaques). Thus, the causative relation between HIV and AIDS was accepted by the scientific and medical community in 1984 and was further verified through the later isolation of HIV type 2 in West African patients with AIDS. The relation was also supported by the clinical efficacy of drugs that specifically inhibit HIV enzymes and the demonstration that mutations in one of the coreceptors for HIV (CCR5) make some persons highly resistant to HIV infection and AIDS.
Although the scientific evidence is overwhelming and compelling that HIV is the cause of AIDS, the disease process is still not completely understood. This incomplete understanding has led some persons to make statements that AIDS is not caused by an infectious agent or is caused by a virus that is not HIV. This is not only misleading, but may have dangerous consequences. Before the discovery of HIV, evidence from epidemiologic studies involving tracing of patients’ sex partners and cases occurring in persons receiving transfusions of blood or blood clotting products had clearly indicated that the underlying cause of the condition was an infectious agent. Infection with HIV has been the sole common factor shared by AIDS cases throughout the world among men who have sex with men, transfusion recipients, persons with hemophilia, sex partners of infected persons, children born to infected women, and occupationally exposed health care workers.
The conclusion after more than 28 years of scientific research is that people, if exposed to HIV through sexual contact or injecting drug use for example, may become infected with HIV. If they become infected, most will eventually develop AIDS.
