seroepidemiology of human hydatid cyst in jahrom

The most common determinant for hydatidosis in human population is the confirmed cases per year or ‎those undergoing surgery, but these are only a few cases of infection. Hydatidosis is one of the ‎important health problems in Iran; therefore, seroepidemiological studies of hydatidosis can be an ‎essential step to promote the social health and prevent this disease by determination of positive cases. In this descriptive cross-sectional study, 1096 sera were randomly collected from the patients referred ‎to a clinical laboratory in Jahrom from 2006 to 2007. They were tested by ELISA for IgG against ‎Ecchinococcus granulosus. During sampling, demographical features of these patients were recorded ‎and the results were analyzed in SPSS.‎ Anti‏-‏Ecchinococcus granulosus IgG was detected in 69 (6.3%) out of 1096 sera including 45 (65.2%) ‎males and 24 (34.8%) females. In 46-60 year old cases, the prevalence rate was higher than the others ‎‎(21 cases, 5.7%). The rates of seropositivity in rural and urban areas were 7.54% and 5.24%, ‎respectively. There was no significant difference between seropositivity of hydatid cyst and variables ‎such as gender, age groups and the area of living (P0.05). The results showed that the seroprevalence of hydatidosis was 6.3% in Jahrom. There was a higher ‎seropositivity in rural areas as compared to urban areas but there was no significant difference ‎between seropositivity of hydatid cyst and area of living.‎
