From February through June 1999, seven human immunodeficiency virus (HIV)-infected young persons were identified in a small town in rural Mississippi. Two persons were identified through routine voluntary HIV testing during sexually transmitted disease (STD) evaluations, and five were identified subsequently through contact investigation by the local health department. Contact investigation identified sex partners and social contacts (i.e., persons who shared social surroundings) and defined a social network of 122 sex and social contacts. Seven (9%) of 78 persons tested from the social network were HIV-infected. Within the social network, a sexual contact network of 44 persons (the seven HIV-infected persons and their sex partners) was identified. The Mississippi State Department of Health asked CDC to join the investigation to describe further the cluster and help direct prevention efforts. This report summarizes the investigation of this cluster and underscores the need for HIV prevention and treatment in rural areas.
1999年2月至6月期间，在密西西比州农村的一个小镇上发现了7名感染人类免疫缺陷病毒（HIV）的年轻人。其中两人是在性传播疾病（STD）评估期间通过常规自愿HIV检测发现的，另外五人随后通过当地卫生部门的接触者调查被发现。接触者调查确定了性伴侣和社会接触者（即共享社会环境的人），并确定了一个由122个性接触和社会接触者组成的社交网络。在该社交网络接受检测的78人中，有7人（9%）感染了HIV。在这个社交网络中，确定了一个由44人组成的性接触网络（7名HIV感染者及其性伴侣）。密西西比州卫生部请求疾病控制与预防中心（CDC）加入调查，以进一步描述这一聚集性病例并协助指导预防工作。本报告总结了对这一聚集性病例的调查，并强调了农村地区进行HIV预防和治疗的必要性。
