Background & Aims: Cutaneous leishmaniasis (CL) has been endemic in Bam district for many years and several epidemics have already occurred. Following a silent period, another outbreak of CL occurred after the earthquake in ۲۰۰۳. This study was performed to find the trend of CL during ۲۰ years (۱۹۸۸-۲۰۰۷) in Bam district. Methods: In a retrospective study, data of ۲۹۳۹۵ CL patients were collected from medical records of Center for CL Control and Treatment and also from previous published studies and analyzed. Results: Before the earthquake there were three periods of outbreak, control and silent. The highest prevalence (۸.۳%, ۶۷۳۴ cases) was in ۲۰۰۰, whereas the lowest (۰.۲%, ۲۱۵ cases) was in ۲۰۰۳ just prior to the earthquake. Again, in ۲۰۰۶ CL prevalence increased to an epidemic level (۲.۶%, ۲۸۸۰ cases). During these ۲۰ years, age of patients has increased and after the earthquake males infected more than females. Lesion sites has changed from face to hands and legs. The causative agent and the vector have been Leishmania tropica and phlebotomus sergenti, respectively. Conclusion: Epidemiology of CL varies with environmental changes and due to the immunity after infection, the incidence rate becomes equivalent to the birth rate. Increase in the prevalence of CL after the earthquake is mainly due to the immigration of non–immune individuals to this area. In endemic areas with frequent natural disasters such as earthquake, it is very essential to consider preventive programs in advance.
