已知内脏利什曼病在索马里沿谢贝利河（中）和朱巴河（下）流域以及在肯尼亚与乌干达和东部各省交界的裂谷部分地区流行。从2000年5月到2001年8月，我们诊断出904例VL。患者来自横跨肯尼亚东北部、索马里南部和埃塞俄比亚东南部的瓦吉尔和曼德拉地区。在索马里北部也发现了少量病人。这些地区以前不是VL的流行地，或者在流行之前只有散发病例。我们描述了疫情的特征，并回顾了该地区VL的历史。不寻常的降雨模式、营养不良以及感染利什曼的人口为寻求食物和安全而迁移可能是导致此次疫情的原因。
Visceral leishmaniasis (VL) was known to be endemic in Somalia along the basins of the (Middle) Shebelle and (Lower) Juba rivers, and in Kenya in parts of the Rift Valley, on the border with Uganda and the Eastern Provinces. From May 2000 to August 2001, we diagnosed 904 patients with VL. The patients came from an area which spanned the Wajir and Mandera districts of north-eastern Kenya, southern Somalia, and south-eastern Ethiopia. Small numbers of patients were also seen in northern Somalia. These areas were either previously non-endemic for VL, or had only sporadic cases prior to the epidemic. We describe the features of the outbreak and review the history of VL in the region. Unusual rainfall patterns, malnutrition, and migration of a Leishmania-infected population seeking food and security may have contributed to this outbreak.
