This report describes a contact investigation conducted in rural South Carolina to identify, counsel, and educate persons infected with or exposed to the human immunodeficiency virus (HIV). Starting with one HIV antibody-positive man and his 19 sex contacts, we identified 83 sex contacts of HIV antibody-positive men. Of these, 64 were residents of the county and 63 (98%) agreed to be tested for evidence of HIV infection. Eight (13%) were HIV antibody positive. Thirty-six initially HIV antibody-negative men were reevaluated at a six-month follow-up visit, and three had seroconverted during this time. Of 25 men who reported practicing anal receptive intercourse, 13 (52%) were HIV antibody positive vs none of 43 men who reported strictly anal insertive intercourse. Comparing reported numbers of sexual contacts for the six-month periods before and after our initial investigation, the mean numbers of named sex contacts decreased by 82% for antibody-positive men and 54% for antibody-negative men. None of the men reported using condoms before entering the study; at the six-month follow-up visit, four (80%) of five of the antibody-positive men and 25 (69%) of 36 of the antibody-negative men reported using condoms at least some of the time.
本报告描述了在南卡罗来纳州农村地区开展的一项接触者调查，以识别、咨询和教育感染或接触人类免疫缺陷病毒（HIV）的人员。从一名HIV抗体阳性男子及其19名性接触者开始，我们识别出了83名HIV抗体阳性男子的性接触者。其中，64名是该县居民，63名（98%）同意接受HIV感染证据检测。8名（13%）为HIV抗体阳性。36名最初HIV抗体阴性的男子在6个月的随访中接受了重新评估，其中3名在此期间发生了血清转化。在报告有接受肛交行为的25名男子中，13名（52%）为HIV抗体阳性，而在报告只有插入式肛交行为的43名男子中无人为HIV抗体阳性。比较我们初步调查前后6个月期间报告的性接触次数，抗体阳性男子的指名性接触平均次数减少了82%，抗体阴性男子减少了54%。在进入研究前，所有男子均报告未使用避孕套；在6个月的随访中，5名抗体阳性男子中有4名（80%）、36名抗体阴性男子中有25名（69%）报告至少有时会使用避孕套。
