We used kernel density and scan statistics to examine the spatial distribution of cases of pediatric and adult American cutaneous leishmaniasis in an urban disease-endemic area in Salta Province, Argentina. Spatial analysis was used for the whole population and stratified by women > 14 years of age (n = 159), men > 14 years of age (n = 667), and children < 15 years of age (n = 213). Although kernel density for adults encompassed nearly the entire city, distribution in children was most prevalent in the peripheral areas of the city. Scan statistic analysis for adult males, adult females, and children found 11, 2, and 8 clusters, respectively. Clusters for children had the highest odds ratios (P < 0.05) and were located in proximity of plantations and secondary vegetation. The data from this study provide further evidence of the potential urban transmission of American cutaneous leishmaniasis in northern Argentina.
我们使用核密度和扫描统计来检查阿根廷萨尔塔省一个城市流行地区的小儿和成人美国皮肤利什曼病病例的空间分布。空间分析用于整个人口以及按女性> 14 岁（n = 159）、男性> 14 岁（n = 667）和< 15 岁儿童（n = 213）进行分层。尽管成年人的核密度几乎涵盖了整个城市，但儿童的分布在城市的外围地区最为普遍。针对成年男性、成年女性和儿童的扫描统计分析分别发现了 11、2 和 8 个集群。儿童集群的优势比最高（P < 0.05），且位于种植园和次生植被附近。本研究的数据进一步提供了阿根廷北部美国皮肤利什曼病潜在城市传播的证据。
