Fig 3.
Comparison of snakebite incidence maps for snakebite incidence.
Contour lines demarcate incidence higher than (A) 0.003 (B) 0.00398 (i.e. National rate) (C) 0.005.
Fig 4.
Comparison of probability contour maps (PCMs) for snakebite incidence.
pMaps represent probability that snakebite incidence in each area exceeds: (A) 0.003, (B) 0.00398 (i.e. National rate) an (C) 0.005. Contour lines represent P = 0.3 (dash lines) and P = 0.7 (solid lines); green colour area represents the exceedance probability < 0.3 and red colour are represents the exceedance probability > 0.7.

Comparison of envenoming incidence.
Contour lines demarcate incidence higher than (A) 0.001, (B) 0.00151(i.e. National rate) and (C) 0.025.

Comparison of probability contour maps for envenoming bites.
Maps represents probability that envenoming bite incidence in each area exceeds: (A) 0.001, (B) 0.00151 (i.e. National rate) and (C) 0.025; contour lines represent P = 0.3 (dash lines) and P = 0.7 (solid lines); green colour area represents the exceedance probability < 0.3 and red colour are represents the exceedance probability > 0.7.
