PaulKing - 07 Jan 2005 04:52 GMT 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. 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. Smith GL, Smith KF. Lack of HIV infection and condom use in licensed prostitutes. Lancet. 1986;1392. 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. Altough 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 reported by David W. Rasnick, Ph.D., in a letter published by the British Medical Journal Sex has nothing to do with AIDS.
Of course, sex-trade workers taking 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.

Background. Sexually transmitted diseases (STDs) enhance human immunodeficiency virus (HIV)-1 susceptibility, but few studies have examined the reciprocal effect of HIV-1 on STD acquisition.Methods. Data from a prospective cohort study conducted among female sex workers in Mombasa, Kenya between 1993 and 2003 were used to determine the effect of HIV-1 infection on STD susceptibility. The cohort included 1215 HIV-1-seronegative women who underwent monthly HIV-1 and STD screening, of whom 238 experienced seroconversion to HIV-1 during follow-up. Andersen-Gill proportional-hazards models were used to compare the incidence rates for genital-tract infections (syphilis, genital ulcer disease [GUD], Neisseria gonorrhoeae infection, Chlamydia trachomatis infection, Trichomonas vaginalis infection, vulvovaginal candidiasis, and bacterial vaginosis) in HIV-1-seropositive versus HIV-1-seronegative women, after controlling for sexual behavior and other potential confounding factors.Results. HIV-1 infection was associated with a significantly higher incidence of GUD (hazard ratio [HR], 2.8; 95% confidence interval [CI], 2.0-3.9), gonorrhea (HR, 1.6; 95% CI, 1.1-2.2), and vulvovaginal candidiasis (HR, 1.5; 95% CI, 1.3-1.8). The risks of GUD and vulvovaginal candidiasis increased with progressive levels of immunosuppression.Conclusions. The increased incidence of genital-tract infections among HIV-1-seropositive women could promote the spread of both HIV-1 and other STDs, particularly in areas where these conditions are highly prevalent.

Background. The objective of the present study was to compare the sociodemographic characteristics and sex work patterns of women involved in the traditional Devadasi form of sex work with those of women involved in other types of sex work, in the Indian state of Karnataka.Methods. Data were gathered through in-person interviews. Sampling was stratified by district and by type of sex work.Results. Of 1588 female sex workers (FSWs) interviewed, 414 (26%) reported that they entered sex work through the Devadasi tradition. Devadasi FSWs were more likely than other FSWs to work in rural areas (47.3% vs. 8.9%, respectively) and to be illiterate (92.8% vs. 76.9%, respectively). Devadasi FSWs had initiated sex work at a much younger age (mean, 15.7 vs. 21.8 years), were more likely to be home based (68.6% vs. 14.9%), had more clients in the past week (average, 9.0 vs. 6.4), and were less likely to migrate for work within the state (4.6% vs. 18.6%) but more likely to have worked outside the state (19.6% vs. 13.1%). Devadasi FSWs were less likely to report client-initiated violence during the past year (13.3% vs. 35.8%) or police harassment (11.6% vs. 44.3%).Conclusion. Differences in sociobehavioral characteristics and practice patterns between Devadasi and other FSWs necessitate different individual and structural interventions for the prevention of sexually transmitted infections, including human immunodeficiency virus infection.

Oh really. They why are prostitutes NOT a CDC high risk group?
GMCarter - 08 Jan 2005 11:13 GMT >"Many sex workers have HIV." > >Oh really. They why are prostitutes NOT a CDC high risk group? First, who says CDC claims they are not?
You?
Well. Oddly, I find relying on your opinions to be unreliable.
See: http://www.cdc.gov/mmwr/preview/mmwrhtml/mm5021a3.htm First paragraph notes: "As a bloodborne and sexually transmitted infection, HIV has variable patterns of transmission and impact among world regions and has disproportionately affected disadvantaged or marginalized persons such as commercial sex workers, injection drug users, men who have sex with men (MSM), and persons living in poverty."
and regarding heterosexual transmission, also note: http://www.cdc.gov/hiv/pubs/facts/hispanic.htm
The pie charts underscore that among Latinas, heterosexual transmission is a primary route of infection.
Another: http://www.niaid.nih.gov/factsheets/womenhiv.htm Note the third paragraph: "Worldwide, more than 90 percent of all adolescent and adult HIV infections have resulted from heterosexual intercourse. "

Don't mix up Third World statements with American statistics and risk groups.

Can HIV Prevention Make a Difference for Men Who Have Sex With Men?
Have we made any progress in the gay community? Absolutely. Men who have sex with men (MSM) were hit hard with HIV early in the epidemic, and remain the group predominantly affected by AIDS nationally. Recent publications have highlighted increased HIV infection in certain MSM populations, drawing the dangerous conclusion that prevention is not working in the gay community. Prevention does work, and many gay/bisexual men would not be alive today if it weren't for rigorous prevention efforts. In the second decade of this epidemic, it's extremely important to balance anecdotes with the weight of scientific evidence that prevention can, indeed, make a difference.
In 1990, MSM accounted for 73.2% of AIDS cases, but declined to 68.7% in 1994. Clearly, most of the decline occurred in White MSM, whose percentages declined from 51.2% to 45.5%. No such declines were observed for African-American, Asian-American, or Native-American MSM.(1)
While AIDS cases among certain segments of MSM have declined, another wave of infection threatens the gay community if commitment to HIV prevention should falter. We can learn a lesson from the public health experience with tuberculosis. In 1969 the federal government provided $20 million for prevention efforts. Tuberculosis cases went down and with the decrease came further decreases in funding, until twenty years later tuberculosis cases had increased past the level from 1969. This is called a "u-shaped curve of concern", where public health improvements lead to diminished funding, which leads to increased new cases.(2) Funding and dedication to HIV prevention efforts must not follow a similar route.
Why are some men still taking risks? J ust because safer sex is effective at preventing HIV, doesn't mean it's easy. Continuing safer sex behavior over a long time is difficult; we all know that it's easier to start a diet than to stay on one. For many men in the gay community, the challenge is not to start having safer sex, but to do so consistently and for the long haul.(3)
In the second decade of the epidemic, the gay community is struggling with the fact that AIDS is here to stay, and that the prospect of a cure is far away. Overwhelming psychological, cultural and spiritual issues surrounding living in the midst of an epidemic often overcome the ability or desire to remain uninfected.(4)
Can prevention reduce new infections? Yes. Significant and substantial reductions in HIV incidence, risk behaviors, incident AIDS cases, and surrogate markers for risk behaviors (like rectal gonorrhea) have been observed, especially among White MSM aged 30 or beyond.(5)
In San Francisco, CA, new HIV infections reached a high of 8,000 in 1982. In 1992, the estimated number of new HIV infections was 1,000. Comprehensive community-based HIV prevention programs targeted towards gay and bisexual men in the early to mid-1980s certainly contributed to this dramatic reduction in new HIV infections.(6)
Rates of rectal gonorrhea, an indicator of male-to-male transmission, have declined significantly across the US. In New York City, rates declined from 1,577 in 1982 to 50 in 1994. In Denver, CO, rates declined from 354 in 1985 to 10 in 1994.(5)
What's working now? HIV prevention programs using small group counseling, community outreach, community mobilization, stress reduction counseling, peer education, and skills training have been effective among all segments of MSM: men in epicenter cities, men in rural communities, young men, adolescents, men of color, and bisexual men.
AIDS education led by peers on a community level is effective at reaching higher-risk men. In several medium-sized towns, the most popular people in social settings were trained to deliver AIDS risk-reduction messages to their friends and acquaintances in gay bars. As a result, fewer men practiced unprotected sex.(7)
The STOP AIDS Project, which grew out of focus groups conducted early in the epidemic in San Francisco, CA, uses community outreach and small group counseling to reduce HIV risk. About 8,000 men are reached annually, and about 1,800 attend workshops. Self-reported rates of unprotected anal intercourse declined after the workshops, from 25.1% to 19.4%, with even greater differences among HIV positive men.
Who is prevention missing? Young MSM continue to be at high risk for HIV infection. In California between 1987 and 1991, HIV incidence among men born 1960-64 increased 216% in Los Angeles County and 206% in San Francisco. One study estimated that a 20-year old MSM has a 20.2% chance of seroconverting before reaching age 25.(8)
MSM of color in the US are disproportionately affected by the HIV epidemic.(9) By March 1993, Latinos comprised 17% of all diagnosed AIDS cases in the US, yet represented only 9% of the general population.(10) In Washington, DC, White MSM showed a 16% decrease in AIDS incidence between 1988 and 1993, while African-American MSM showed a 63% increase.(11)
Men who use alcohol or drugs are at a much higher risk for contracting HIV. A recent study of gay men in substance abuse treatment found alarming levels of high-risk sex, levels that approached those recorded before the AIDS epidemic.(12)
What needs to be done? Clearly, the scope of HIV among MSM calls for a national effort to reduce new infections. In Canada, the federal government sponsored a simultaneous survey of 4,803 men in 35 cities across the country. Results were published for the public, and based on this, a national intervention project for MSM i s being sponsored by the Canadian AIDS Society.(13) The US is more than ready for a similar national effort.
Maintenance of safer practices must be encouraged and examined. Without assistance otherwise, return to unsafe practices should be expected. Service providers and scientists need to study this phenomenon and be prepared to assist those who might or have already relapsed from safer sexual practice either occasionally or altogether.
Better surveillance systems are needed. Vital and important HIV data should be much easier to find. Regular systems of surveillance that keep closer track of changes in the epidemic are needed, so that rapid responses can be mobilized in target groups where the spread of HIV is occurring.
Interventions targeted to "missed" populations are urgently needed. Although programs exist across the country, shamefully few have been evaluated for effectiveness. A comprehensive HIV prevention strategy uses multiple elements to protect as many of those at risk of HIV infection as possible. Continued funding, evaluations, and controlled trials of HIV prevention interventions for diverse groups of MSM must become a priority.(14)
