detected between 2013 (labelled 1) and 2016 (labelled 4). 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

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.
