移动的、以社区为基础的艾滋病毒检测可能有助于在南非实现普遍的艾滋病毒检测。我们比较了南非德班的iThembalabantu诊所部署的基于移动的和诊所的艾滋病毒检测项目检测人群的产量、地理分布和人口统计学特征。从2011年7月至11月，对4，701名受试者进行了检测; IPHC检测者中艾滋病毒感染率为35%，移动的检测者中为10%（p<0.001）。移动的测试者的平均年龄（22-37岁）和男性百分比（26-67%）各不相同。移动的场所的艾滋病毒流行率从0%到26%不等。测试人员比离家最近的诊所走得更远;移动的测试人员更有可能离家≥ 5 km进行测试。移动的艾滋病毒检测可以改善检测的可及性，并确定艾滋病毒流行率高的检测地点。个人经常访问移动的测试站点比他们最近的诊所离家更远。地理空间技术有助于优化移动的部队的部署，以最大限度地提高难以接触人口的产量。
Mobile, community-based HIV testing may help achieve universal HIV testing in South Africa. We compared the yield, geographic distribution, and demographic characteristics of populations tested by mobile- and clinic-based HIV testing programs deployed by iThembalabantu Clinic in Durban, South Africa. From July–November 2011, 4,701 subjects were tested; HIV prevalence was 35% among IPHC testers and 10% among mobile testers (p<0.001). Mobile testers varied in mean age (22–37 years) and % males (26–67%). HIV prevalence at mobile sites ranged from 0% to 26%. Testers traveled further than the clinic closest to their home; mobile testers were more likely to test ≥ 5 km away from home. Mobile HIV testing can improve testing access and identify testing sites with high HIV prevalence. Individuals often access mobile testing sites farther from home than their nearest clinic. Geospatial techniques can help optimize deployment of mobile units to maximize yield in hard-to-reach populations.
