Application of GIS in epizootiological surveillance of swine trichinellosis in one endemic district in Serbia*

Application of new tools for epizootiological investigations in veterinary medicine, such as Geographical Information Systems (GIS), offers a new approach and possibilities for the eradication or control of infectious diseases. GIS is particularly useful for research conducted in small areas strongly impacted by man. Trichinellosis is a world-wide zoonosis, which is endemic in some European countries, Balkan district and Serbia in particular. There are very few data on GIS application in the field of trichinellosis. We here present the application of GIS for mapping Trichinella spp. occurrence and spatial and temporal patterns of Trichinella infection in one endemic district in Serbia. Settlements with trichinellosis were marked and particular points of interest were designated. Data on prevalence of Trichinella infection in domestic swine accompanied by location of foci indicated the existence of disease geographical stationarity. This first report on GIS application in Serbia will facilitate trichinellosis surveillance and monitoring of Trichinella spp. circulation among domestic pigs, and populations of synanthropic and sylvatic animals
