Hydatid cyst is one of the most common Zoonotic diseases occurs due to infection with larval stage of Echinococcus granulosus parasite. Based on epidemiological reasons, World Health Organization has introduced Iran as a hyperendemic region. This study aims to investigate the clinico-epidemiological characteristics of patients with hydatid cyst in Iran. We used information registered in the surveillance system of the Iranian Ministry of Health and Medical Education attributed to Mazandaran province. Data were entered into SPSS software V.20 after refinement and analyzed using percent frequency, mean, standard deviation and statistical tests such as Chi-square and Exact Fisher tests. Mean (SD), minimum and maximum ages of the participants were 42.2 (17.2), 6 and 72 years respectively. Most of them were female (63.4 %) and mean (SD) number of cysts was 1.6 ± 0.8. Of them, 51.2 % living in rural areas and 58.5 % of them were housewives. Liver was the most common organ involved. The main diagnostic procedures were radiography and CT scanning. The majority of participants (73.2 %) consumed unsterilized vegetables. This study showed women more susceptible compared to men probably because of more exposure to parasites through vegetables. We also found the liver as the most affected organ in hydatid cyst patients.
