Geographic location of dip tanks and foot and mouth disease primary outbreaks. The dip tanks are presented in black and grey dot (n = 4960). The FMD primary outbreaks are presented as black dots (the size of the dots is proportional to the number of outbreaks, n = 110) from 1931 to 2016 in Zimbabwe. The protected areas (where African Buffalo populations are present) are presented as grey areas. The dot-line represented the Mashonaland West province for which the dataset for dip tanks location was not complete.
