Differences by geographical information system in prevalence of disease in a farm animal practise

In the present study, the incidence of diseases in cattle in the area of a veterinary practice was analyzed spatially. Furthermore, the relationship between the incidence of diseases and the distance to geographical elements was investigated. For this study, all cattle farms that were customers of the ambulatory clinic of the animal hospital in Zurich (Tierspital Zurich) were exactly localized on a map. From clinical and treatment data program (Oblon Data (R)) all services and drugs between January 1st 2013 and December 31st 2013 were evaluated and added as attributes to the according farm. Along with the data of the animals kept on the respective farm, the relationship between prevalences and geographical elements was analyzed. Using these data, it was possible to define fifteen diseases of which incidences were spatially analyzed using a geographic information system (GIS). The results indicate that also on the level of a veterinary practice there are spatial differences in the incidence of diseases to find. However, the majority of diseases occur mainly in regions where the density of animals is also very high. As in earlier findings, this suggests that the size, the management and the proximity of a farm to the next farm (density) have a strong impact. A connection could be found between the distance to the geographical elements street, water and forest and the incidences of gastrointestinal parasitosis, claw disorders, reproduction disorders and cryptosporidiosis.
