Author Contributions

CAG, SIH, and RWS wrote the manuscript and developed and implemented the biological rules of exclusion. CAG designed and implemented the databases. CAG, PWG, and RWS compiled and mapped PfAPI and PfPR data. AJT processed the environmental data required for the temperature and aridity masks. CAG implemented the masks and extracted populations at risk. AMN advised on GIS applications. DLS advised on the age-standardization of PfPR data.
