We analyzed georeferenced data on mobility and HIV infection from the 2009 Demographic and Health Survey of Lesotho. We found ∼50% of the population traveled in the preceding year. By constructing gender-specific mobility maps, we discovered that travel is highest in the urban areas bordering South Africa and in the mountainous interior of the country. For both genders, increased mobility was associated with increased levels of "recent" sexual behavior. Notably, mobility was only associated with an increased risk of HIV infection for men who traveled frequently. We discuss the implications of our results for designing effective treatment programs and HIV interventions.
我们分析了来自莱索托2009年人口与健康调查的地理定位的流动和艾滋病毒感染数据。我们发现约50%的人口在前一年有过出行。通过构建针对性别的流动地图，我们发现与南非接壤的城市地区以及该国山区内部的出行率最高。对于男女两性而言，出行增加都与“近期”性行为水平上升有关。值得注意的是，只有频繁出行的男性的流动才与艾滋病毒感染风险增加相关。我们讨论了研究结果对设计有效治疗方案和艾滋病毒干预措施的意义。
