An outbreak of leishmaniasis took place in the Ein el-Tal residential area near Aleppo during January and February 2001, due to the build-up of the sand fly population as a result of a breakdown in the adjacent municipal sewerage system.
2001年1至2月期间，由于邻近市镇下水道系统不通，沙蝇大量聚集，阿勒颇附近的Ein-el-Tal居民区爆发了一场利什曼病。
