The envelope containing most of the detected cases is defined as the OD outbreak area. C) The distribution of pig farmers in the territory. Black filled symbols stand for surveyed farms (which are all outdoor farms), close grey symbols for outdoor farms that were not surveyed, open symbols for indoor farms, circles for farms rearing pigs for consumption, triangles for pet pig farms and squares for wild boar farms. The envelope defines the OD outbreak area.
