Hiv patients who are treated with antiretrovirals, give the virus more by. This is evident from a European survey among almost a thousand homosexual couples.
For the study, 972 couples from fourteen European countries for eight years followed. They consisted of a partner with a virus and one without the virus. They had in the study period, unprotected anal sex with each other.
The results of the research, published Thursday in the prestigious British medical journal The Lancet.
They let the researchers see that the virus not through sexual acts can be passed as so-called retroviral medication (hiv-inhibitors) are used to the hiv virus in the blood and bring it back to a level where it will no longer detect.
Hiv-inhibitors provide, among other things, that hiv-patients are not aidsverschijnselen. At the time that the body of an hiv patient by the virus may not protect against other viruses and bacteria, there is the issue of aids.
Evidence that antiretrovirals potential for transmission removal
“Our results provide conclusive evidence that the chances of gay men who are hiv-inhibitors of the hiv-virus transfer is zero,” says co-principal investigator Alison Rodger of University College London.
Rodger believes that this “powerful message” can help the global aids epidemic to end to prevent groups at high risk for contamination run the virus spread. During the eight-year study period occurred treatment with antiretrovirals, approximately 472 new besmettingsgevallen, according to researchers.
Fifteen of the subjects walked during the test period, a hiv-infection, but genetic research showed that those who are of a different sexual partner received.
Still 1.8 million new infections per year
The research embroidered builds on the results of a previous study among heterosexual couples in whom one of the partners is hiv-positive. Also there brought antiretrovirals, the risk of new infections to zero.
Since the beginning of the aids epidemic in the eighties of the last century have been worldwide more than 77 million people became infected with hiv. Almost half, compared to 35.4 million people, died of aids.
Experts say that the annual number of aids deaths is falling and that the number of people who are hiv-inhibitors get worldwide increases, but with 1.8 million new cases per year, the number of infections remains high.
