今天发布的两个试验的结果首次提供了证据,表明服用抗逆转录病毒药物可以预防异性恋男性和女性的HIV感染。

这种预防策略,被称为暴露前预防(PrEP),最初被证明对男同性恋者有效。但PrEP在4月份遭受挫折,当时一项在非洲女性中测试药物Truvada的研究由于缺乏疗效而不得不提前停止。然而,新的试验数据表明,根据该领域专家的说法,这种方法在预防HIV传播的探索中具有广泛的潜力。

Hannah Waters is a science writer fascinated by the natural world, the history of its study, and the way people think about nature. On top of science blogging, she runs the Smithsonian's Ocean Portal, a marine biology education website, and is science editor for Ladybits.

Hannah is a child of the internet, who coded HTML frames on her Backstreet Boys fanpage when she was in middle school. Aptly, she rose to professional science writing through blogging (originally on Wordpress) and tweeting profusely. She's written for The Scientist, Nature Medicine, Smithsonian.com, and others.

Before turning to full-time writing, Hannah wanted to be an oceanographer or a classicist, studying Biology and Latin at Carleton College in Northfield, Minnesota. She's done ecological research on marine food webs, shorebird conservation, tropical ecology and grassland ecosystems. She worked as a lab technician at the University of Pennsylvania studying molecular biology and the epigenetics of aging. And, for a summer, she manned a microphone and a drink shaker on a tour boat off the coast of Maine, pointing out wildlife and spouting facts over a loudspeaker while serving drinks.
