Cancer cell infecting the bloodSince the HPTN 052 study, we have concluded that having a viral load HIV undetectable disease greatly reduces the risk of HIV transmission. But how safe is condomless sex if one partner has an undetectable viral load?

The PARTNER study is a European study to great extent with the aim of examining the transmission of HIV among seronegative (men who have sex with men) heterosexual or MSM couples who do not regularly use condoms expressly or take pre-exposure prophylaxis (PrEP or post-exposure prophylaxis (PEP, the English Post Exposition Profilaxy). The positive partner had to have a HIV viral load count was lower than 200 copies / ml at baseline.

Seven hundred and seventy-six couples are currently enrolled, with data already contributed some 900 couples / year and an estimated 44.400 sexual acts. About 30% of sex acts were reported to have been without condom use. There was no HIV transmission events between the partners in the study, both heterosexual and homosexual. The authors were cautious in their conclusions, but said the higher estimate of risk for HIV (ie the 95% confidence interval) was 0,45% per annum and for anal sex 1% per year. The researchers speculate that these rates translate into a maximum of 5% chance of transmission over a period of 10 years.


While it is important to remember that sex without a condom still carries with it the risk of other sexually transmitted infections, the findings of this study are profoundly important. The PARTNER study confirms the simple fact that HIV treatment is prevention. In the real world, where condom use is imperfect, HIV positive people in treatment can prevent transmission of HIV to their partners of the same sex or different sexes.

There is also the possible legal implications for legal systems that criminalize sex between discordant people, an issue that was pioneered by Swiss government statements. Along with HPTN 052, this study gives further support to treatment as an essential component of HIV prevention programs.

claudiusNote from the editor of Soropositivo Web Site: Note that the text is clear and this stance, the stance of treatment as prevention is not 100% safe (like everything in medicine) and that, in my opinion, based on my personal experience throughout twenty years old, the proposal is good as a way to increase security. In other words, the ideal is that there is, yes, sexual intercourse, but that it is safe, with the use of condoms, leaving treatment as prevention as a second defense zone, in warlike terms, because that is what it is about, a war between a virus and the human race; Mostly I have published several texts about the problem itself, such as this text, this other text and even more this show excellent results, it is necessary to take into account that even among the most “caxias” in the treatment, which includes me , adherence may not be total and, in some cases, there may be a migration, from one organism to the other, of a modified virus that is resistant to PrEP and PEP. In this case, there would be transmission, to a subject who may not be aware of the fact that he is being infected by a resistant virus and, what is worse, he can transmit it to another person and this to another and another and another and so on and so on. , in the end, we would have a completely “new” epidemic with a virus resistant to truvada and, by table, to other antiretrovirals (read, in another window, on another website on cross-resistance.
