Since the start in 1988 of the present epidemic of kala-azar (visceral leishmaniasis) in western Upper Nile state in southern Sudan, the epidemiology of the disease in all parts of the Sudan where kala-azar has been reported was reassessed by the Leishmaniasis Research Group in Khartoum. In this paper, the spread of the epidemic is described among a nomadic tribe originating from southern Kordofan state, who migrate every year with their cattle to the Bentiu area in western Upper Nile state where the epidemic is still raging. 200 cases from this tribe were seen in Khartoum; another 56 cases were found during a field trip to the area. In addition, the Bentiu area was visited, where 301 cases were under treatment and another 52 of 1120 individuals screened were confirmed parasitologically. 20 cases of post-kala-azar dermal leishmaniasis were found. Parasites isolated from the nomadic tribe were of the same zymodeme as parasites isolated previously from the Nuer in western Upper Nile. The epidemiological findings in each state are discussed in relation to the tribes that were affected and the ecology of the area.
自1988年苏丹南部上尼罗州西部出现黑热病（内脏利什曼病）疫情以来，喀土穆的利什曼病研究小组对苏丹境内所有报告有黑热病的地区的该病流行病学情况进行了重新评估。本文描述了疫情在一个来自科尔多凡州南部的游牧部落中的传播情况，该部落每年带着牲畜迁移到上尼罗州西部的本提乌地区，那里疫情仍在肆虐。在喀土穆诊治了该部落的200例病例；在对该地区进行实地考察期间又发现了56例。此外，还走访了本提乌地区，那里有301例正在接受治疗，在对1120人进行筛查时，另有52例经寄生虫学确诊。发现了20例黑热病后皮肤利什曼病病例。从该游牧部落分离出的寄生虫与先前从上尼罗州西部的努尔人分离出的寄生虫属于同一酶谱型。针对受影响的部落和该地区的生态环境，对每个州的流行病学调查结果进行了讨论。
