Abstract
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 to 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.
摘要
基于社区的流动艾滋病毒检测可能有助于在南非实现艾滋病毒普遍检测。我们比较了南非德班的伊滕巴拉班图诊所开展的流动艾滋病毒检测项目和基于诊所的艾滋病毒检测项目所检测人群的检测率、地理分布及人口统计学特征。2011年7月至11月，共检测了4701名受试者；在基于综合初级卫生保健的检测者中艾滋病毒感染率为35%，在流动检测者中为10%（p<0.001）。流动检测者的平均年龄（22 - 37岁）和男性比例（26% - 67%）各不相同。流动检测点的艾滋病毒感染率在0至26%之间。检测者前往的地点比离家最近的诊所更远；流动检测者更有可能在离家≥5公里的地方接受检测。流动艾滋病毒检测可以改善检测机会，并识别艾滋病毒感染率高的检测地点。人们前往流动检测点的距离通常比最近的诊所更远。地理空间技术有助于优化流动检测单位的部署，以在难以到达的人群中实现最大检测率。
