今天釋出的兩個試驗的結果首次提供了證據,表明服用抗逆轉錄病毒藥物可以預防異性戀男性和女性的HIV感染。

這種預防策略,被稱為暴露前預防(PrEP),最初被證明對男同性戀者有效。但PrEP在4月份遭受挫折,當時一項在非洲女性中測試藥物Truvada的研究由於缺乏療效而不得不提前停止。然而,新的試驗資料表明,根據該領域專家的說法,這種方法在預防HIV傳播的探索中具有廣泛的潛力。

美國疾病控制與預防中心(CDC)國家艾滋病、病毒性肝炎、性病和結核病預防中心主任Kevin Fenton在今天早些時候的新聞釋出會上說:“這是首個強有力的、令人信服的證據,表明PrEP可以在這一人群中發揮作用。” “這是一個重要的里程碑。”

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.
