ABSTRACT:
Fascioliasis is a zoonosis of global distribution caused by the parasitic trematode Fasciola spp. Infection in humans can occur in areas endemic for animal fascioliasis, suggesting the need for studies on this parasitosis and its determinants. This exploratory study aimed to analyze the spatial distribution of bovine fascioliasis in the state of Santa Catarina, Brazil, based on cases notified between 2015 and 2017 in a state abattoir, located in the municipality of Orleans, and to associate disease occurrence with altitude, temperature, and rainfall. The research was conducted at Centro Universitário Barriga Verde (UNIBAVE)/Orleans, SC and Fundação Oswaldo Cruz/Rio de Janeiro, RJ. During the study period, the abattoir received animals from 58 municipalities in that state. Of the animals slaughtered in that period, 10,81% were infected with Fasciola hepatica. Presence of bovine fascioliasis infection was identified in the South and Southeast regions of the state, with higher prevalence rates in the latter. There was an association between low altitudes and higher occurrence of cases in the municipalities assessed. In addition, prevalence of bovine fascioliasis was higher in municipalities with high temperatures and low rainfall. Therefore, these results should be considered for planning disease control measures in the South and Southeast regions of the state of Santa Catarina.
