Study confirms the impact of ART on prevention
Monday, 16 May 2011
A study known as HPTN 052 shows men and women living with HIV reduced their risk of transmitting HIV to their sexual partners by taking oral antiretroviral medicines. The study, which was supported by the United States National Institute of Health (NIH), began in April 2005 and enrolled 1,763 predominantly heterosexual (97%) HIV-discordant couples from 13 sites across Africa, Asia, and the Americas. It is the first large-scale study to confirm that ART greatly reduces HIV transmission risk in HIV-discordant couples, where the person living with HIV has a CD4 cell count of between 350 -550.
