Some epidemiological and ecological aspects of Zoonotic cutaneous leishmaniasis (ZCL) in Ouarzazate province, southern Morocco, were explored with the objective of analyzing ZCL distribution and associated ecological factors. Information on cutaneous leishmaniasis patients attending the local health centers of Ouarzazate during the period 2002-2009 was gathered and compiled. Urban, peri-urban, rural origin, precipitation, wind speed, temperature, water irrigation, dam volume, and altitude were studied. The findings show that the disease affected 5405 person during this period; the major part was found in the municipalities near both oases (desert oasis) and water resources, with a high concentration of cases in the peri-urban area. The highest percentage of cases was recorded mainly in September. Considerable associations were found between relative humidity and wind speed with ZCL occurrence. A large number of cases were recorded in areas with altitude ranging from 800 to 2000 m.a.s.l. and spatial precipitation from 15 to 150 mm. The statistical analysis showed a strong association between water storage volume and water irrigation with the annual ZCL occurrence recorded in the downstream area (Zagora province). The results will lead us to understand ZCL risk areas for effective control. Further work is needed mainly for gathering these variables in one single and simplest model.
为分析摩洛哥南部瓦尔扎扎特省人兽共患皮肤利什曼病（ZCL）的分布及相关生态因素，对其一些流行病学和生态学方面进行了探索。收集并整理了2002年至2009年期间前往瓦尔扎扎特当地卫生中心就诊的皮肤利什曼病患者的信息。研究了城市、城郊、农村来源、降水量、风速、温度、水灌溉、水坝蓄水量和海拔高度。研究结果表明，在此期间该疾病影响了5405人；大部分病例出现在绿洲（沙漠绿洲）和水资源附近的市镇，城郊地区病例高度集中。病例百分比最高主要记录在9月。发现相对湿度和风速与ZCL的发生之间存在显著关联。大量病例记录在海拔800至2000米、年降水量15至150毫米的地区。统计分析表明，下游地区（扎戈拉省）记录的年ZCL发生率与蓄水量和水灌溉之间存在密切关联。这些结果将有助于我们了解ZCL的风险区域以便进行有效控制。主要需要进一步开展工作，以便将这些变量整合到一个单一且最简单的模型中。
