Result of the largest and longest study of the heterosexual transmission of ‘HIV’ in the United States:

  We followed 175 HIV-discordant couples over time, for a total of approximately 282 couple-years of follow up [...]

  We observed no seroconversion after entry into the study.

The ‘Prostitute’ Paradox

If ‘AIDS’ (‘HIV’) was sexually transmitted, we should find it in sex-trade workers. The following references, including five studies published in prestigious scientific journals, demonstrate no sexual transmission.

  In this study, the authors estimated overall and cause-specific mortality among prostitute women. They recorded information on prostitute women identified by police and health department surveillance in Colorado Springs, Colorado, from 1967 to 1999. The authors assessed cause-specific mortality in this open cohort of 1,969 women [...]

  Violence and drug use were the predominant causes of death, both during periods of prostitution and during the whole observation period. [...] Deaths from acquired immunodeficiency syndrome occurred exclusively among prostitutes who admitted to injecting drug use or were inferred to have a history of it.

Potterat J J et al. Mortality in a Long-term Open Cohort of Prostitute Women. Am J Epidemiol 2004;159:778-785.

  During a 36-month period, a multidisciplinary team manned a van that visited the major location of open prostitution in the Tel Aviv area [...]

  All 128 females who did not admit to drug abuse were seronegative.

  A thorough search of recent literature fail to demonstrate unequivocal seropositivity among British, French, German, Italian, or Dutch prostitutes without drug histories.

Michael Wright also report this study in A Former AIDS Researcher Has Second Thoughts, part one: Manufacturing the AIDS Scare.

  In order to determine whether prostitutes operating outside of areas of high drug abuse have equally elevated rates of infection, 354 prostitutes were surveyed in Tijuana, Mexico [...]

  None of the 354 [blood] samples [...] was positive for HIV-1 or HIV-2

  Condoms were used [...] for less than half of their sexual contacts.

  Only 4 female prostitutes (1%) admitted to ever having abused intravenous drugs.

  Infection with HIV was not found in this prostitute population despite the close proximity to neighboring San Diego, CA, which has a high incidence of diagnosed cases of AIDS, and to Los Angeles, which has a reported 4% prevalence of HIV infection in prostitutes.

David Crowe also report this study in Referenced Quotes about Transmission of HIV and AIDS.

  In order to evaluate the frequency of sexual transmission of human immunodeficiency virus (HIV) among promiscuous heterosexuals, we studied the prevalence of HIV infection among a group of predominantly Caucasian call girls and women working for escort services and massage parlors in New York City. In the 78 subjects studied, the mean age was 31.6 years and the mean duration of prostitution was 5.1 years. Study participants each had a median of 200 different sexual partners in the preceding year. [...]

  none of the 72 non-drug-abusers were seropositive for HIV. This study indicates that despite their promiscuity, HIV infection is still uncommon in call girls in New York City

  448 licensed female prostitutes in Nuremburg, West Germany, were studied in March and April 1986.

  No prostitute tested was anti-HIV positive [...] they had been prostitutes for 77 months on average [...] The mean number of clients was 13 per week [...]

  This heterosexually very active group of women has remained free from HIV infection.

  In September, 1985, we collected 56 samples of blood in the rue Saint-Denis, the most notorious street in Paris for prostitution. [...]

  No prostitute was seropositive.

  These women, aged 18-60 have sexual intercourse 15-25 times daily and do not routinely use protection. Although contracting AIDS is greatly feared by these women, only 15 used condoms with all their customers.

  [...] none of the Paris prostitute was a drug addict.

Brenky-Faudeux D, Fribourg-Blanc A. HTLV-III antibody in prostitutes. Lancet. 1985;2:1424.

  The same results were reported from Amsterdam, one of the world’s centers of legalized prostitution. When several hundred non-drug using prostitutes were studied, investigators found no HIV-positive women even though they averaged more than 200 clients per year

Coutinho RA, van der Helm TH. [No indications for LAV/HTLV-III in non-drug-using prostitutes in Amsterdam]. Ned Tijdschr Geneeskd, 1986;130(11):508. As presented by David W. Rasnick, PhD, in a letter published by the British Medical Journal Sex has nothing to do with AIDS.

We saw that sexual transmission has not been demonstrated in sex-trade workers. Of course, those who take hard drugs are more likely to become sick, it has nothing to do with ‘HIV’ or ‘AIDS’. Strong drugs have a proven immune suppressive effect, and intravenous drugs injections often carry some foreign proteins, adding an extra burden on the immune system.
