Persons whose behaviors may increase their risk for infection with human immunodeficiency virus (HIV) but who may be underserved by existing HIV prevention and testing programs (in part because of limited access) include those who are homeless, chemically dependent but not in treatment, and mentally ill. To assess the prevalence of high-risk behaviors for HIV infection, the acceptance of HIV counseling and testing, and HIV seropositivity in such populations in Colorado Spring, Colorado (1995 population: 465,885), the El Paso County Department of Health and Environment (EPCDHE) conducted a study during July-September 1995. This report summarizes the results of the study, which indicate that such presumably underserved persons are accessible, commonly report high-risk behaviors and previously have been tested for HIV infection and that social isolation, in part, accounted for the low seroprevalence of HIV in this study population.
行为可能增加感染人类免疫缺陷病毒（HIV）风险，但现有HIV预防和检测项目可能服务不足（部分原因是获取途径有限）的人群包括无家可归者、药物依赖但未接受治疗者以及精神疾病患者。为评估科罗拉多州斯普林斯市此类人群中HIV感染高危行为的流行情况、对HIV咨询和检测的接受程度以及HIV血清阳性率（1995年人口：465,885），埃尔帕索县卫生与环境部（EPCDHE）于1995年7月至9月开展了一项研究。本报告总结了该研究结果，结果表明，这类可能服务不足的人群是可以接触到的，他们普遍报告有高危行为，并且之前接受过HIV感染检测，而且社会隔离在一定程度上导致了该研究人群中HIV血清阳性率较低。
