A couple of years ago, European researchers began studying more than a thousand couples, gay and straight, in which one member had been infected with H.I.V. and the other hadn’t. These couples weren’t using condoms. But the infected partner was taking antiretrovirals successfully; the virus was suppressed, undetectable in the blood. The researchers published their results in July 2016 in the Journal of the American Medical Association.
