今天發布的最新研究顯示，人類免疫缺乏病毒（HIV）抑制藥物，可讓男同志伴侶間即便未用保險套從事性行為，也不會傳染愛滋病毒。
法新社報導，這項研究追蹤歐洲各地近1000對男同性伴侶達8年，受試伴侶裡一人為HIV陽性反應者並接受「抗反轉錄病毒療法」（ART），另一人則為HIV陰性反應。
這段期間，醫生們未發現任何受測伴侶間相互傳染HIV病毒的個案，大大增添ART能終止HIV傳染的希望。
這項研究發表在英國醫學雜誌「刺胳針」（The Lancet），共同帶領這項研究、來自倫敦大學學院（University College London）的羅傑斯（Alison Rodgers）說：「我們的發現提供確切證據，在接受ART治療的前提下，男同志伴侶間的HIV傳染為零。」
「病毒量低到難以測出，就能使HIV無法傳染。這有助於透過防止HIV病毒傳染，終止愛滋病，解決許多HIV患者所面臨的污衊和歧視。」
研究人員估計，這段研究期間，這項新療法讓所有受試伴侶之間成功避免了470次HIV傳染。
儘管近年有所進展，但HIV和其引發的致命疾病仍是全球最大的健康危機之一。超過2100萬人現正接受ART治療，但這僅佔全球受HIV感染者的59%。
不過這項研究的人員也提及到一些侷限性，包括受試者HIV呈陰性者的平均年齡是38歲，但大多數HIV傳染發生在年齡25歲以下的人。
此外，目前接受ART治療的患者，餘生必須每天服藥，但治療療程常因許多原因而被打斷。
不過也有專家認為，讓男同志伴侶多年來從事不用保護措施的性行為而不傳染病毒，實務上幾無價值。北卡羅來納大學（UNC）「全球衛生及傳染病研究所」專家柯恩（Myron Cohen）就說，及時發現遭感染者並提供有效治療，就足以終止HIV傳染風險、回到接近正常健康狀態。
