WILCHES, Christian et al. Presence of infection by Fasciola hepatica in inhabitants from the valle de San Nicolás, eastern Antioquia. Infect. [online]. 2009, vol.13, n.2, pp.92-99. ISSN 0123-9392.

Introduction: The Programa de Estudio y Control de Enfermedades Tropicales (PECET) at the Universidad de Antioquia has found a prevalence of 90% of hepatic fasciolasis in cattle from valle de San Nicolás, eastern Antioquia. Objective: In this study the presence of infection in the human population that is in contact with livestock was determined. Materials and methods: The presence of antibodies in serum samples from 61 residents of the area and whose jobs require constant contact with cattle was determined by an ELISA test. Risk behaviors for acquisition of the parasite as well as the clinical and symptoms for the study population were also determined. Results: Three of the 61 sera tested were positive for the presence of specific antibodies to F. hepatica, corresponding to a prevalence of infection of 4.9%. These three subjects reported manipulating pasture for livestock and drinking water from streams near grazing fields. Only one person referred jaundice in the last six months. Conclusions: The findings of this study document the presence of F. hepatica in the human population that is in contact with infected livestock and identify the risk behaviors for acquisition of the disease among the inhabitants of the area. It is important to know the incidence and prevalence of infection in both human and animal population, to adopt preventive measures for those that are in contact with sick cattle, and treatment of infected people.
