A STUDY OF HYDATID CYST CASES IN IRAN-A SYSTEMATIC REVIEW

Hydatid cyst is an infectious disease common between humans and animals which is spread worldwide and has been known to humans since old times. Different accounts have been presented on the individual characteristics of people suffering from hydatid cyst, clinical course, different treatment and diagnosis methods, and its recurrence. The hydatid cyst infection exits in various parts of the world, and Iran is on the endemic belt of the disease, in a way that different rates have been reported in different studies. Depending on climate conditions, social customs, nutritional status, and the amount of contact with canidae animals, incidence rates of up to 10% have been reported in human populations for these diseases. The present research is a systematic review study. In order to find the studies conducted in Iran, the articles in national and international journals and dissertations available on Magiran, Iranmedex, SID, Google-scholar, and PubMed databases were used, and more than 100 articles were found, among which 14 articles related to the topic that met the criteria for entering the study were investigated. The data collected were analyzed by SPSS version 18 through using descriptive-analytical statistics and chi-squared statistical test (X2 test). The results of the study showed that infection rate in the liver of cows to hydatid cyst is 62%, while lung infection in native and hybrid breeds in the city of Baneh is 7.75%. In rural area of Tehran, 437 person, 276 women and 161 men, in the age range of 4-76 years of age were studied, and one person was positive and seven persons were suspected to the disease. The results of the present study showed that, although the infection rate of hydatid cyst in urban and developed parts of Iran is at an acceptable and satisfactory level, the statistics in lesser-developed areas is endemic and alarming and deserves paying more attention and developing organized plans to control the disease.
