Sumario:AIM: The aim of this study was to investigate the prevalence of human and animal fascioliasis in Ilam Province, Iran. BACKGROUND: Fascioliasis, caused by Fasciola hepatica, is one of the most important zoonotic diseases. Snails are an intermediate host. Human infection with the parasite can led to hypertrophy and hyperplasia in bile duct. It also economic importance and further information is essential about the epidemiology of the parasite in Ilam province. PATIENTS AND METHODS: The study on animals was descriptive and retrospective. All records from abattoirs were analyzed. It was conducted on 27242 indigenous animals including 17055 sheep, 5703 goats, and 4484 cattle. For the study of human Fascioliasis infection 600 human sera, from person among 5-80 year old, were collected and ELISA test was used for identification of IgG antibody to Fasciola hepatica by commercial kit. RESULTS: The overall prevalence of Fasciola hepatica among 27242 slaughtered animals was 0.98%. Out of 267 domestic animals, 98 sheep, 28 goats and 141 cattle were infected with the parasite. The highest and lowest infection rate of 3.14% and 0.1% were cattle and goat, respectively. The prevalence of IgG antibody was0.66% (n = 4) against Fasciola hepatica in humans. Three infected people were living in rural areas. The highest infection rate (3 people) was found in women. CONCLUSION: Ilam province is among the areas where the prevalence of Fasciola hepatica is low. This is probably due to the drought in the region in recent years that makes conditions difficult for the survival of snails, the intermediate hosts. But there is a risk of the disease increasing in incidence, in this region.
