An estimated 250,000 persons living with human immunodeficiency virus (HIV) in the United States are not aware of their infections and their risk for transmitting HIV. As part of CDC's Advancing HIV Prevention Initiative, identifying persons with undiagnosed HIV infection and linking them to medical care and prevention services is a national priority. In 2003, a 2-year demonstration project was begun with nine community-based organizations (CBOs) in seven cities to evaluate the effectiveness of using a social network strategy at multiple sites to identify persons at risk for HIV infection and direct them to HIV counseling, testing, and referral (CTR). In this strategy, HIV-positive persons and HIV-negative persons at high risk (i.e., recruiters) are enlisted to recruit for CTR persons from their social, sexual, and drug-use networks (i.e., network associates [NAs]) believed to be at risk for HIV infection. This report summarizes preliminary results from the first year of this 2-year project, which indicated that 133 persons recruited 814 NAs, resulting in 46 newly identified HIV infections (approximately 6% of all persons tested). Health departments and CBOs should consider this strategy as an effective method for recruiting persons for CTR and identifying those with undiagnosed HIV infection.
据估计，美国有25万感染人类免疫缺陷病毒（HIV）的人并不知道自己已被感染，也不清楚他们传播HIV的风险。作为美国疾病控制与预防中心（CDC）推进HIV预防计划的一部分，识别未被诊断出感染HIV的人并将他们与医疗护理及预防服务联系起来是一项国家优先事项。2003年，在七个城市与九个社区组织（CBO）开展了一个为期两年的示范项目，以评估在多个地点使用社交网络策略来识别有HIV感染风险的人并引导他们接受HIV咨询、检测及转诊（CTR）的有效性。在该策略中，HIV阳性者和高危HIV阴性者（即招募者）被招募来从他们的社交、性及吸毒网络中招募被认为有HIV感染风险的人（即网络关联者 [NA]）接受CTR。本报告总结了这个为期两年项目第一年的初步结果，结果显示133人招募了814名网络关联者，新发现了46例HIV感染（约占所有检测者的6%）。卫生部门和社区组织应将此策略视为招募人员接受CTR及识别未被诊断出感染HIV者的有效方法。
