Results: Out of the 1,236 individuals enrolled in this survey, 688 were diagnosed as cases of CL, giving an infection rate of 55.7%. Children constituted 244 (35.5%) of infected cases. Majority of skin lesions were found in the Extremities 524 (76.2%). The average duration of skin lesions was 3.6 months (±1.6). Conclusion: This outbreak among IDPs affected a large proportion of inhabitants of the newly established villages in north Sudan. Preventive measures might have help control such outbreaks.
