Malaria is a disease with focal distribution. In Brazil, settlement and gold mining areas in the Legal Amazon region present a great concentration of cases. This paper analyzes the spatial distribution of malaria cases taking into consideration environmental and social factors in the Vale do Amanhecer settlement in the municipality of Juruena, Mato Grosso, Brazil. In 2005, 359 autochthonous cases were notified in the settlement. Using the Kernel method, areas of greater and lesser intensities of case numbers were identified. The areas of greater intensity presented 290 cases and those of lesser intensity, 64 cases. The intensity of distribution varied within the settlement, thus indicating areas of great intensity of cases favoring transmission, like gold mining areas. Therefore, although the settlement was considered to be the main focus for malaria, there were specific factors within it that, once identified, could contribute towards the disease control.
疟疾是一种呈局部分布的疾病。在巴西，法定亚马逊地区的定居点和金矿开采区病例高度集中。本文考虑了巴西马托格罗索州茹雷纳市阿马内塞河谷定居点的环境和社会因素，分析了疟疾病例的空间分布情况。2005年，该定居点报告了359例本地病例。采用核密度估计法，确定了病例数强度较高和较低的区域。病例数强度较高的区域有290例病例，强度较低的区域有64例病例。定居点内分布强度各不相同，这表明病例数强度高的区域有利于疾病传播，如金矿开采区。因此，尽管该定居点被认为是疟疾的主要疫源地，但其中存在一些特定因素，一旦识别出来，有助于疾病控制。
