This is especially true in Africa where most new infections are among heterosexuals. In these populations, vaginal sex is the predominant route of infection.
This study follows up on an earlier study by the same authors examining per-act heterosexual HIV transmission probabilities. It is a systematic review and analysis of all available study data related to the likelihood of heterosexual HIV transmission. The authors reviewed 43 published studies conducted in various countries that reported per-act heterosexual HIV-1 transmission probability estimates. The authors concluded that the average male to female risk of HIV transmission is. The authors' three objectives were to provide summary estimates of HIV-1 transmission probabilities per heterosexual contact; do in-depth single variable and multivariable analysis to explore the reasons for different study results; and estimate the role of risk factors such as viral load and STIs on the likelihood of transmission.
To the Editor. The observed case was in a couple described as unique in that vaginal and penile bleeding during intercourse was noted. On the other hand, male-to-female transmission was estimated to be De Vincenzi I.
