PARTNER Study Reveals 'No One' w/ Undetectable Viral Load Transmits HIV
AIDS Map reports that results from the first two years of the PARTNER study have shown that no HIV-positive individual (homosexual or heterosexual) with an undetectable viral load has transmitted HIV:
The second large study to look at whether people with HIV become non-infectious if they are on antiretroviral therapy (ART) has found no cases where someone with a viral load under 200 copies/ml transmitted HIV, either by anal or vaginal sex.
Statistical analysis shows that the maximum likely chance of transmission via anal sex from someone on successful HIV treatment was 1% a year for any anal sex and 4% for anal sex with ejaculation where the HIV-negative partner was receptive; but the true likelihood is probably much nearer to zero than this.
When asked what the study tells us about the chance of someone with an undetectable viral load transmitting HIV, presenter Alison Rodger said: "Our best estimate is it's zero."
The final results of the study are due in 2017. We encourage you to read the full AIDS Map report here as we're sure it will answer many questions regarding the study.
In the meantime, we'd love to hear how the results of this study have impacted your perception of HIV, HIV treatment, and the stigma of sex with HIV-positive partners.
