Rift Valley Fever Environmental Suitability and Spillover Potential Geospatial Estimates


General Info
Institute for Health Metrics and Evaluation (IHME)
Coverage type 
Time period covered 
01/1995 - 12/2016
Data type
  • Subnationally representative

This dataset includes predictions for the environmental suitability of Rift Valley Fever (RVF) transmission at the monthly level, as well as calculations of spillover potential, which combines suitability predictions with human and livestock population data. It also includes occurrence data extracted from a literature review combined with that downloaded in October 2018 from the Food and Agriculture Organization of the United Nations’ (FAO) EMPRES-i database of RVF occurrences in mammals.

The dataset includes the following:

  • GeoTIFF raster files for pixel-level mean environmental suitability predictions for each of the 12 calendar months and average months of suitability per year for 1995-2016
  • CSV files of each administrative level 2 units’ average spillover quintile for each of the 12 calendar months and average months per year in the top quintile of spillover values
  • Extracted occurrence data
  • Code files and custom polygons used to generate the estimates
