The participants’ characteristics such as age, gender, occupation, place of residence, organinvolved, clinical signs and, diagnosis and treatment methods were collected using a questionnaire. Thestatistical analysis was carried out using SPSS (version ۲۳) software package.Results: The results revealed that ۵۳.۲۱% and ۴۶.۷۹% of patients were females and males, respectively.Most cases were uban residents (۵۷.۶۹%), and ۶۲.۱۸% of them were housewives. Liver involvementwas the most common localization of hydatid cysts reported in ۷۳.۷% of patients. The main diagnosticprocedures were computed tomography scanning and indirect hemagglutination (IHA). Abdominal painwas reported in ۶۲.۲% of cases, and the most common treatment method for the disease was surgical(۸۴.۶%).
