An enormous trove of evidence has just been released that supports the increasingly solid global consensus that having an undetectable viral load thanks to antiretroviral (ARV) treatment is associated with effectively zero chance of transmission.
The long-awaited results from the PARTNER2 study of mixed-HIV-status gay male couples are finally in. Presented today at the International AIDS Conference in Amsterdam (AIDS 2018), the prospective observational study saw zero transmissions between study partners when the HIV-positive partner had a fully suppressed viral load, even after nearly 77,000 condomless anal sex acts. Together with the 12,000 condomless sex acts documented between such partners in the Opposites Attract study, researchers now have data on 89,000 such acts between male partners.
