Studies on the leishmaniases in the Sudan. 1. Epidemic of cutaneous leishmaniasis in Khartoum

Abstract
A recent outbreak of cutaneous leishmaniasis (CL) in Khartoum province, the first ever reported, involved about 10,000 recorded cases. The peak incidence was in September 1986. It was widespread all over the province, but the most affected areas were along the banks of the River Nile. People of both sexes, all age groups, different ethnic origins, and all socio-economic classes were equally affected, suggesting that this epidemic was a new occurrence among a non-immune population. A leishmaniasis clinic was established and 736 cases were treated and studied. The control measures, responsible parasite, possible animal reservoir, and vector are discussed. Possible contributory factors were mass population movement from known endemic areas of CL in Khartoum, expanding towns and new settlements in previously uninhabited areas, high population densities of sandflies, and an increase in the rodent population, including Arvicanthis species.
