Since the start in 1988 of the present epidemic of kala-azar (visceral
leishmaniasis) in western Upper Nile state in southern Sudan, the epi
demiology of the disease in all parts of the Sudan where kala-azar has
been reported was reassessed by the Leishmaniasis Research Group in K
hartoum. 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 we
re seen in Khartoum; another 56 cases were found during a field trip t
o 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 leishma
niasis were found. Parasites isolated from the nomadic tribe were of t
he same zymodeme as parasites isolated previously from the Nuer in wes
tern Upper Nile. The epidemiological findings in each state are discus
sed in relation to the tribes that were affected and the ecology of th
e area.
