Epidemiology, Associated Factors and Treatment Methods of Cutaneous Leishmaniasis Based on Previous Data from 2013 to 2018 in Ilam, Western Iran

Objective: The aim of this study was to evaluate the epidemiology, clinical presentation and types of treatment of cutaneous leishmaniasis (CL) in the province of Ilam (Western Iran) in 5 years (from May 2013 to January 2018). This cross-sectional study involved patients diagnosed with CL who were referred to Mehran City Health center. Methods: All patients were diagnosed by clinical and parasitological (Giemsa staining of lesion to observe the parasite) methods. Moreover, a structured questionnaire on demographic data including age, sex, occupation, number and site of the lesions, treatment regimen was administered to each case. Results: In total, 2001 positive CL cases were observed in this study. The highest prevalence of CL was reported in the autumn season and mainly among male subjects residing in urban communities. The prevalence of CL varied with the age group: higher in the age group of 1–10 years than other groups. Besides, hands and faces were the most affected regions of the body. Most of the cases (47.35%) were managed by topical treatment (glucantime) and cryotherapy followed by systemic treatment (pentavalent antimony) 26.85%. Conclusions: The prevalence of disease varied with age, increasing the prevalence rate in children due to their habitats, the highest prevalence in autumn due to climatic conditions. These findings help to better discuss the prevention and treatment of infections.
