An End To Aids Is In Sight

Conclusive results of an eight-year study find that men on an antiretroviral HIV treatment have a zero risk of passing on the virus to sexual partners

An antiretroviral treatment developed by researchers at University College London (UCL) and the University of Copenhagen has reduced the possibility of passing on the virus that causes AIDS to zero. The study, named PARTNER2, involved nearly 1,000 European gay couples in which one partner was HIV positive and the other HIV negative. Over the course of the eight-year study, the couples reported having sex without the use of condoms nearly 80,000 times. None of them was found to pass on the virus to the HIV-negative partner. The researchers estimated that based on the type and frequency of sexual contact, the treatment prevented around 500 HIV transmissions.
