Based on a 19 comprehensive and geographically representative census of herds and farms in the area, more than 20 2000 cattle were randomly chosen and their blood sampled during field survey. Data on livestock 21 farming practices were recorded for each farm. All data were mapped within a GIS to generate new 22 information on spatial constraints in the area. 23 Surveys results were analysed and serological prevalence data were modelled using logistic 24 regression. The model allowed identification and quantification of risk factors. In a second step the 25 statistical model was used predictively on the entire farm population in the area.
