Viral load, HIV treatment, and HIV transmission in serodiscordant male homosexual couples

艾滋病毒治疗可降低人体内艾滋病毒的浓度。在异性恋者中，目前的研究将确定艾滋病毒治疗在防止艾滋病毒进一步传播方面的有效性。相比之下，对同性恋男性的此类研究很少，在澳大利亚，同性恋男性占艾滋病毒携带者的70%或更多。这项研究将对200多对男性同性恋夫妇进行为期四年的跟踪调查，其中一对是HIV阳性，另一对是阴性，以调查HIV治疗在预防HIV中的作用。

HIV treatment reduces the concentration of HIV in the body. In heterosexuals, current studies will determine the effectiveness of HIV treatment in preventing onwards HIV transmission. In contrast, there has been very little such research in homosexual men, who comprise 70% or more of people with HIV in Australia. This study will follow for four years over 200 male homosexual couples in which one is HIV positive and the other negative, to investigate the role of HIV treatment in HIV prevention.
