Echotomographic and serologic screening for hydatidosis was carried out in 1,650 subjects aged over 5 years in a village located in a high risk region of central Tunisia. Echotomography detected liver cysts in 6 subjects (prevalence rate: 3.6 per 1,000). These 6 cases were among the 7 positive cases detected by ELISA. In all 6, the diagnosis of liver cysts was confirmed. No other localization was found in any of the subjects including one with a positive ELISA and a normal echotomographic examination. This work demonstrates the high feasibility of echotomography in the field and confirms the high prevalence rate of hydatidosis in the community.
