Absract: Visceral Leishmaniasis (VL) is a protozoan disease caused by Leishmania donovani and transmitted by phlebotomus sand fly. The disease is endemic in Sudan and large area of tropics. It has been reported in eastern Sudan since the beginning of the twentieth century. This is a cross-sectional study conducted in Tabark Allah Village, eastern Sudan to measure the seroprevalence of visceral Leishmaniasis. Samples of blood sera were collected from 373 individuals selected by systematic random technique. The samples were examined using Direct Agglutination Test (DAT) to detect the anti-leishmania antibodies. Demographic and socio-economic data were obtained by direct interview with the study group using a pre-tested questionnaire.The seroprevalence at a cut off ≥ reciprocal titre of 3200 was found to be 17.2% which was more prevalent among children (70.2%) with p value of 0.000, compared to adults. Family income had a significant association with the seroprevalence of visceral Leishmaniasis (p value: 0.05).
