BREAKTHROUGH: Study Shows Zero HIV Transmissions When Undetectable

New research shows probability of transmission is zero while on antiretroviral treatment.

A groundbreaking study on antiretroviral treatment showed that the drugs can disable HIV and stop sexual transmission. The randomized study of 1,700 couples was conducted by UNC-Chapel Hill and confirmed a 2011 study that stated ART could prevent transmission of HIV if it is taken reliably. The medications suppress HIV and can render it virtually harmless, unable to transmit to a sexual partner.
