Replying to my own posting, I have further information on this topic: Here is the actual text of Dr. Quinn's report on that study: ==================== Viral Load and Risk of Heterosexual Transmission of HIV-1 among Sexual Partners T. C. QUINN*, M. J. WAWER, N. SEWANKAMBO, D. SERWADDA, C. J. LI, F. WABWIRE-MANGEN, M. MEEHAN, T. LUTALO, and R. H. GRAY* NIAID. Johns Hopkins Univ., Baltimore, MD; Columbia Univ., New York, NY; Makerere Univ., Rakai Project Team, Uganda Objective: To determine the effect of viral load on the risk of heterosexual transmission of HIV, 415 HIV-discordant (HIV-positive/HIV-negative) couples were followed over a 30-month period in a study of 15,127 people in Rakai district, Uganda. Incidence of transmission and acquisition/100 person-years (py) were determined in relation to HIV viral load, sociodemographic and behavioral characteristics, and active STDs. Results: The male partner was HIV infected in 228 (55%) and the female was HIV positive in 187 (45%). 90 (21.7%) of 415 discordant couples seroconverted (incidence 11.8/100 py). The transmission rate from males to females was 12.0/100 py and not statistically different from female-to-male transmission (11.6/100 py). Incidence was highest among 15 to 19-year-olds (15.2/100 py) and among uncircumcised males (16.7/100 py); no seroconversions occurred in circumcised males (p<0.0001). Mean viral load was significantly higher in transmitters vs. non-transmitters (90,254 vs. 38,029; p=0.01). There was a dose response of higher transmission with increasing viral load (p<0.0001), with no transmissions <1500 copies/mL, and up to 23.0/100 py for a viral load >50,000 copies/ml. In multivariate analyses, HIV viral load was the major predictor of HIV risk; each log10increment in viral load was associated with a 2.45-fold increased risk of transmission (95% CI 1.85*3.26). Conclusion: HIV-1 viral load was the major predictor of heterosexual transmission, with no differences by gender. However, circumcision among men reduced risks of acquisition. With no transmissions at viral loads <1500 copies/ml, reductions in viral load with antiretrovirals or vaccines may reduce transmission of HIV-1. ============================ The entire conference data is available at http://www.retroconference.org/. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- NOTE: other factors must be taken into account (than circumcision & viral load) and what the other environmental and hygienic circumstances that resulted in these228 males infected with the virus must also be studied. At best, (as indicated in his conclusions) one can agree that in this particular study and among this particular group of individuals in Uganda, "circumcision among men reduced risks of acquisition" but there is a far cry from "reduced risk" to "protects" as in the news release. I think we do need to be clear that we should avoid advocating a clear misinformation such as "Circumcision protects men from HIV" and I further hope no 13 year old boy gets that news release and think for a second that since he is circumcised, he is "protected" from HIV and can do whatever he likes. >>> Tony Cisse <[log in to unmask]> 3/February/2000 04:34pm >>> Jaajef wa G-L, I recieved this through another mailing list and thought it was interesting enough to pass on...
