Factors affecting variations in exposure to infections by Leishmania donovani in eastern Sudan
AbstractA cross-sectional survey was carried out in Gedaref state, eastern Sudan to investigate the prevalence of positive leishmanin skin tests and environmental factors related to Leishmania donovani infection. A total of 3835 people living in 11 villages in 3 regions were screened. Soil types and tree densities were determined in 33 villages inhabited by 44 different tribes. The highest rates of positive skin tests were in Rahad region [33.9%], Atbara [21.6%] and Gedaref [10.6%], with an average of 21.1% for the state. Risk of infection by L. donovani varied significantly between different tribes. Higher densities of Acacia and Balanites spp. trees were in Masaleet villages, suggesting that the relatively high risk of L. donovani exposure in this tribe is due to environmental factors
