边疆疟疾是一种生物、生态和社会人口现象，随着时间的推移，在三个空间尺度上（微观/个人、社区、州和国家）发生作用。我们通过整合来自遥感调查、地面调查和民族志评估的数据来解释这些联系，重点关注巴西朗多尼亚的Macha-dinho定居点项目。空间显式分析表明，边疆定居的早期阶段主要是环境风险，其结果是生态系统的转变促进了达林按蚊的幼虫栖息地。随着森林砍伐的推进以及农业、牧场和城市发展的建立，疟疾传播大大减少，新感染的风险在很大程度上是由人类行为因素驱动的。边境定居点的疟疾缓解战略要求将预防和治疗方法结合起来，并要求卫生部门和农业部门密切合作。最重要的是使特定地块的农业潜力与新移民的经济和技术能力相匹配。同样重要的是提供有效的农业推广服务。
Frontier malaria is a biological, ecological, and sociodemographic phenomenon operating over time at three spatial scales (micro/ individual, community, and state and national). We explicate these linkages by integrating data from remote sensing surveys, ground-level surveys and ethnographic appraisal, focusing on the Macha-dinho settlement project in Rondonia, Brazil. Spatially explicit analyses reveal that the early stages of frontier settlement are dominated by environmental risks, consequential to ecosystem transformations that promote larval habitats of Anopheles darlingi. With the advance of forest clearance and the establishment of agriculture, ranching, and urban development, malaria transmission is substantially reduced, and risks of new infection are largely driven by human behavioral factors. Malaria mitigation strategies for frontier settlements require a combination of preventive and curative methods and close collaboration between the health and agricultural sectors. Of fundamental importance is matching the agricultural potential of specific plots to the economic and technical capacities of new migrants. Equally important is providing an effective agricultural extension service.
