目的了解红树地区昏睡病的传播和传播情况，为其防治提供依据。方法在几内亚Forecariah红树林地区，对19例昏睡病患者和19例对照者在其生活区域（家中、田间和供水点）进行随访。所有的职业场所和路径都被绘制出来，然后置于其环境背景中。结果昏睡病患者的空间占用比对照组更广泛、更多样化。他们每天步行的距离是对照组的两倍，平均多两个工作地点，其中大多数位于红树林。确定了具有较高传播风险的活动（水稻栽培、独木舟码头的使用）以及高风险地区和途径。结论提出了针对传播风险区域的昆虫学控制策略。将其纳入控制规划将使整个地区传统病媒控制规划所需的努力减少86%。在特定地点（如独木舟码头和高风险路径）进行的医疗调查也应能够更好地针对风险最高的人群。
OBJECTIVES To provide a better understanding of sleeping sickness transmission and spread in mangrove areas to optimize its control.METHODS In the Forecariah mangrove area, Guinea, 19 sleeping sickness cases and 19 matched controls were followed up in their living areas (at home, in fields and at water points). All occupational sites and pathways were mapped and then placed in their environmental context.RESULTS The sleeping sickness cases displayed a significantly broader and more diverse spatial occupation than the controls. They covered double the daily walking distances of controls and had on average two more occupational sites, most of which were located in mangrove forests. Activities with a higher transmission risk (rice culture, attendance of pirogue jetties) were identified as well as high-risk areas and pathways.CONCLUSIONS An entomological control strategy targeting transmission risk areas is proposed. Its implementation in a control programme would reduce by 86% the efforts needed for a classical vector control programme throughout the area. Medical surveys set up at specific locations, such as pirogue jetties and high-risk paths, should also enable better targeting of the population at highest risk.
