The following epidemiological data conflict with this announced that HIV was the cause ofAIDS, and an antibody hypothesis. (i) Noncorrelations exist between HIV and AIDS; test for HIV, termed the AIDS test, was registered as a patent for example, the AIDS risks of infected subjects vary >10-fold by Gallo and collaborators (13-15).

Thus HIV became the first virus for which a positive because if it occurs, then only on average 10 years after antibody test is interpreted as an indicator for primary transfusion of HIV, because specific AIDS diseases are not diseases that have yet to come.

HIV acts as a marker for American AIDS risks, than any other human virus (16-21).

This virus-AIDS hypothesis was accepted by most medical Epidemiology is like a bikini: what is revealed scientists, in particular virologists, by 1986 (16-18, 30). is interesting; what is concealed is crucial. Accordingly, the virus was named HIV by an international committee of retrovirologists (30) and became the only basis AIDS is a newly defined syndrome of 25 old parasitic, for the definition of AIDS: "Regardless of the presence of neoplastic, and noninfectious diseases, including in the other causes of immunodeficiency, in the presence of labo- United States 53% pneumonia, 19% wasting disease, 13% ratory evidence for HIV, any disease listed .. indicates a candidiasis, 11% Kaposi sarcoma, 6% dementia, 3% lym- diagnosis of AIDS" (2).

Here this epidemiological evidence is called into deficiencies associated with hemophilia, acting over the long question. time periods said to be latent periods of HIV, have all been identified as pathogenic factors for AIDS-like diseases in Noncorrelations Between AIDS and HIV hemophiliacs (55-61). To determine whether HIV or clinical deficiencies and their treatment cause AIDS in hemophiliacs, AIDS Risks of HIV-Infected Persons Differ 10- to 65-Fold either controlled epidemiological studies comparing matched Depending on Their Country. If AIDS is caused by HIV, the hemophiliacs, with and without HIV, or epidemiological ratio of infected to diseased carriers should be similar in evidence that the mortality of hemophiliacs is increased by different countries. However, in the United States about 10% HIV would be necessary. (or 100,000) (1) of 1 million HIV-positives (16, 18, 49, 50) have Surprisingly, in view of the many claims that HIV causes developed AIDS since 1985, but in Uganda only 0.8% (or AIDS in hemophiliacs, there is not one controlled study that 8000) of 1 million (51), and in Zaire only 0.15% (4636) (52) of has found HIV to be a health risk. There is also no report from 3 million HIV-positives (34). Although AIDS surveillance by any country that the mortality rate of hemophiliacs has some African countries has been questioned, surveillance by increased due to the infection of hemophiliacs with HIV (59). Uganda is reported as "highly successful," providing "the In fact, it appears to be lower than ever (56, 59). About 75% highest number . .. of cases . in Africa" (51). Since the of the 20,000 severe hemophiliacs in the United States are HIV epidemics of both the United States and Africa are said reported to be HIV-positive at least since 1980 to 1982, owing to be new and to have an African origin (17, 20, 36, 45), but to the administration of blood or factor VIII (16, 18, 59, 61, the AIDS risks ofinfected Americans are 10- to 65-fold higher 62).

Moreover, if AIDS equaled opportunistic philiacs may have been HIV-positive for >10 years now (56, infections resulting from immunodeficiency, more, instead of 59). Since 50-100% ofHIV-infected persons are postulated to less, AIDS per HIV carrier would be expected in Africa than develop AIDS after an average latent period of 10 years (18, in the United States. 21, 34), at least half of the 15,000 HIV-positive hemophiliacs AIDS Risks Among HIV-Infected Americans Differ About should have died from AIDS.
