Mean predicted Lassa risk map for West Africa from the Model 2 series with two absence and one presence clusters, with positive localities indicated by stars.

The posterior probability colour scale, from 0.0 (no risk) to 1.0 (highest risk) is shown as an inset. Grey areas are either areas with no suitable imagery (because of cloud contamination; coastal Nigeria and Cameroon) or else are so far from any of the training set sites in their environmental conditions that no predictions are made for them.
