Background: Hydatidosis is one of the most important parasitic zoonosis, which is endemic in Iran like many other countries. However, no comprehensive data are available about its prevalence rate, especially in Zanjan. Awareness of epidemiological aspects of the disease is of great value in prevention and control of the infection. In this regard the present study was carried out for seroepidemiology of human hydatidosis in Zanjan (Islam-Abad area).
Materials and Methods: A total of 2367 serum samples out of 1000 families were collected from over 2 years of age, population of Islam-Abad through randomized clustered method during 2002. Hydatid fluid antigen was prepared from sheep livers and lungs infected with hydatid cysts. Using this antigen, all serum samples were tested by indirect ELISA. Data were analyzed by T-test and Chi- Square.
Results: Out of 2367 tested sera, 71(3%) samples were positive. Positive rate among age groups was not statistically different, as the highest rate belonged to 10-19 and 20-29 years old with 3.6% and 3.3%, respectively. Infection rate was low at the ages over 50 years old. Positive rate in males and females were 2.7% and 3.2%, respectively. Moreover, no correlation was seen between positive rate and education of the population.
Conclusion: Regarding remarkable prevalence of positive cases among this population like other regions of country, prevention and control of the disease should be considered as one of the health priorities in this area. Moreover, for identification of transmission routes and infection sources, more studies are recommended.
