WASHINGTON — An AIDS-free generation: It seems an audacious goal, considering how the HIV epidemic still is raging around the world.

•Studies found treatment-as-prevention could lower an HIV patient’s chance of spreading the virus to an uninfected sexual partner by a stunning 96 percent. In the U.S., new guidelines recommend starting treatment early rather than waiting until the immune system has weakened. Abroad, the United Nations hopes to more than double the number of patients being treated in poor countries to 15 million by 2015.

•Other studies show a longtime AIDS medication named Truvada can prevent infection, too, if taken daily by healthy people who are at risk from their infected sexual partners. The U.S. Food and Drug Administration is expected to decide by fall whether to formally approve sale of Truvada as an HIV preventive.

•A study from South Africa found a vaginal gel containing anti-AIDS medication helped protect women when their infected partners wouldn’t use a condom, generating more interest in developing women-controlled protection.

•Globally, experts also stress male circumcision, to lower men’s risk of heterosexually acquired HIV.
