确定艾滋病毒阳性者中艾滋病毒传播风险行为的比率是公共卫生的优先事项，特别是因为受感染者的寿命更长，因为改进的医疗。很少有研究评估从事高风险活动的艾滋病毒抗体阳性者传染给其伴侣的可能性。从2000年6月至2002年1月，在洛杉矶、密尔沃基、纽约市和旧金山弗朗西斯科的诊所和社区机构中，共对3 723名HIV感染者（1918名男男性行为者[MSM]、978名女性和827名异性恋男性）进行了有关性行为和吸毒行为对传播HIV风险的访谈。不到四分之一的女性和异性恋男性有两个或更多的性伴侣，而59%的MSM报告有多个伴侣。大多数无保护的阴道和肛门性行为发生在与其他艾滋病毒阳性者的关系中。大约19%的妇女、15.6%的男男性行为者和13.1%的异性恋男子与艾滋病毒阴性或血清状况未知的伴侣进行无保护的阴道或肛交。大多数性活跃的参与者透露他们的血清状态，所有的合作伙伴，他们从事疾病无保护的性交。在3个月的报告期内，预计研究参与者的性伴侣中将有30.4例新感染（79.7%是由于与MSM的性互动）。在过去3个月内注射毒品的304名参与者中，有18%的人报告说，他们将使用过的注射设备借给了他人。除了更传统的艾滋病毒检测咨询和关注未感染者的方法外，还需要为艾滋病毒感染者提供强化预防方案，以阻止病毒的未来传播。
Determining rates of HIV transmission risk behavior among HIV-positive individuals is a public health priority, especially as infected persons live longer because of improved medical treatments. Few studies have assessed the potential for transmission to the partners of HIV-positive persons who engage in high-risk activities. A total of 3 723 HIV-infected persons (1918 men who have sex with men [MSM], 978 women, and 827 heterosexual men) were interviewed in clinics and community-based agencies in Los Angeles, Milwaukee, New York City, and San Francisco from June 2000 to January 2002 regarding sexual and drug use behaviors that confer risk for transmitting HIV. Less than one quarter of women and heterosexual men had 2 or more sexual partners, whereas 59% of MSM reported having multiple partners. Most unprotected vaginal and anal sexual activity took place in the context of relationships with other HIV-positive individuals. Approximately 19% of women, 15.6% of MSM, and 13.1% of heterosexual men engaged in unprotected vaginal or anal intercourse with partners who were HIV-negative or whose serostatus was unknown. The majority of sexually active participants disclosed their serostatus to all partners with whom they engaged ill unprotected intercourse. An estimated 30.4 new infections (79.7% as a result Of Sexual interactions with MSM) would be expected among the sex partners of study participants during the 3-month reporting period. Eighteen percent of 304 participants who injected drugs in the past 3 months reported lending their used injection equipment to others. In addition to the more traditional approaches of HIV test counseling and of focusing on persons not infected, intensive prevention programs for persons with HIV infection are needed to stein the future spread of the virus.
