Epidemiology of Fasciola Hepatica in Iran

Fascioliasis is a zoonotic disease. Their greatest importance lies in the economic impact. In order to know the current status of this parasite in the province, we decided to carry out the Epidemiology. We used history-necropsy technique for the diagnosis of this parasitosis in infected bovine animals. When we were suspecting to fascioliasis we did a proper history of the area where the animals were sick. A retrospective study was carried out based on the existent registrations of Fascioliasis discoveries in the bovine slaughterhouse of Ilam province during 3 years successively. In the year of (07-08), 8.48% of the sacrificed animals were infested. The year of (08-09) 6.03% and the third years (09-10) 11.09%. In the (2007-2010) we found a high prevalence of Fascioliasis in animals slaughtered in the province, rising more than one third of the total, with significant differences in proportions (P<0.01) among the three years. The findings were also subcapsular hematomas, venous congestion and fibrous peritonitis. The economic losses were considerable.
