The largest outbreak of human leishmaniasis in Europe took place in Fuenlabrada, Spain, between 2009 and 2017. The University Hospital "12 de Octubre" in Madrid serves the population residing in three districts of Madrid located just north of the outbreak area (Villaverde, Usera, and Carabanchel). Villaverde and Usera are connected by rail to the outbreak area, unlike Carabanchel. We performed a retrospective study including all cases of leishmaniasis diagnosed between 2011 and 2020. Fifty-one cases were documented. In the districts connected by rail to the outbreak area, a higher-than-expected incidence was observed (13.45-15.55 versus 5.2 per 100,000 inhabitants). Apart from the linear distance from the place of residence to the railway tracks, no differences in terms of demographics or risk factors were detected between the populations of the districts. We hypothesize that the direct connection with the outbreak area by rail could explain the higher incidence observed in Villaverde and Usera.
2009 年至 2017 年期间,西班牙富恩拉夫拉达(Fuenlabrada)爆发了欧洲最大规模的人类利什曼病疫情。马德里的 12 月 10 日大学医院(Hospital "12 de Octubre")为马德里三个位于疫情爆发区北部的地区(比利亚韦德(Villaverde)、乌塞纳(Usera)和卡拉班切(Carabanchel))的居民提供服务。比利亚韦德和乌塞纳通过铁路与疫情爆发区相连,而卡拉班切则不然。我们进行了一项回顾性研究,纳入了 2011 年至 2020 年间确诊的所有利什曼病病例。共记录了 51 例病例。在与疫情爆发区通过铁路相连的地区,发病率高于预期(13.45-15.55 比每 10 万人 5.2 例)。除了居住地与铁路之间的直线距离外,两个地区的人口统计学或风险因素方面没有差异。我们假设通过铁路与疫情爆发区的直接联系可以解释在比利亚韦德和乌塞纳观察到的更高发病率。
