Table 4 Weights applied to key variables regarding suitability for endemic and epidemic Rift Valley fever.

From: Application of knowledge-driven spatial modelling approaches and uncertainty management to a study of Rift Valley fever in Africa

Factor Weight: Endemic suitability Weight: Epidemic suitability
Rainfall 0.45 0.55
Land Surface Temperature 0.18 0.06
Elevation 0.08 0.13
Distance to major rivers 0.15 0.17
Distance to minor rivers 0.07 0.04
Livestock density 0.07 0.05
  1. Ordering and allocation of weights was guided by the results of a systematic review of the published literature.
