This study sought to estimate for the first time the prevalence of fascioliasis among the rural population in the Chilean provinces of Curico, Talca, and Linares, while also determining the disease's prevalence among horses and wild rabbits in Curico and Talca and among pigs in Talca. From January 1986 to December 1990 a randomly selected sample of 5,861 persons in the three provinces was given intradermal, complement-fixation, double-diffusion, and immunoelectrophoresis tests to detect antibody to Fasciola hepatica. In addition, the ELISA test was used in Talca and Linares. Fecal specimens from horses and pigs were inspected for eggs, and the liver and bile ducts of rabbits were examined histopathologically. The overall prevalence of infection among the human subjects was 0.70%, with rates of 0.6% in Curico, 0.75% in Talca, and 0.71% in Linares. The prevalences of infection in horses, rabbits, and pigs were 13.5%, 6.1%, and 20.6%, respectively. It is estimated that some 2,000 people are infected in the study area. It is recommended that rabbits be taken into account in all control programs for this zoonosis.
