Fasciola hepatica is a trematode of the subclass Digenea, it has an extensive worldwide distribution, becoming present on all continents and infecting a large number of mammals including man, it produces a disease known as fasciolasis, its main source of transmission is the consumption of food contaminated with feces especially grasses. To carry out its biological cycle, this parasite needs an intermediate host, being a mollusk of the Lymnaeidae family. The liver is the main organ where the lesions occur, the clinical manifestations are usually nonspecific and will vary according to the phase of the disease, which can be acute, chronic or latent. The diagnosis can be made by various methods such as parasitological from flotation or sedimentation techniques, immunological using ELISA tests, and interpretation of the pathological findings at necropsy. Regarding the epidemiology of this parasitosis, since 1980 the number of cases of infected animals has grown significantly, in many countries it has been considered an enzootic disease of bovines causing great economic losses for the livestock and food industry, due to the seizure of carcasses and their high mortality, becoming a pathology of great importance in the veterinary area. Its prevention is mainly focused on the control of intermediate hosts and secondly, the administration of drugs to animals, in endemic areas it is necessary to carry out an immediate sanitary intervention. This review covers relevant aspects about the infection caused by Fasciola hepatica.
