Abstract

Objective: Hydatidosis is a parasitic disorder that has become a significant concern worldwide. Iran is an endemic region for this disease. The present survey aimed to analyze the demographic and epidemiological features of infected cases over a 24-year period in the city of Mashhad, located in Northeast Iran.
Method: Pathology reports and hospital records of all patients with hydatid cyst between 2000 and 2024, were reviewed. Demographic characteristics including age, sex, place of residence, location and number of cysts and relapse were extracted and analyzed using SPSS version 29.
Results: The results revealed that 52.21% of patients were females, and 48.79% were males. Urban and rural areas had a fairly equal frequency of hydatid cyst (50.1% in rural and 49.9% in urban areas). 31.95% of patients were housewives. Lung involvement was the most common localization of hydatid cysts reported in 52.6% of patients, followed by the liver (40.33%). The peak incidence was in the age group of 21-40 years old. Most of patients (92.8%) had involvement of only one organ. 6.25% of them had simultaneous infection in two organs, mostly hepatopulmonary infection. Eighty percent of patients had one cyst. Relapse occurred in 4.5% of cases.
Conclusion: Given the substantial expenses associated with diagnosing and treating Hydatidosis, it is crucial to gather comprehensive data on disease prevalence, transmission patterns, and vulnerable populations to control and prevent the disease.
