A targeting methodology to define target areas and assign ranking based on population and malaria incidence. a Health facility incidence is calculated from the confirmed and unconfirmed incidence data. b Target areas are defined as clusters of ≥25 structures that all lie within a contiguous area generated using 50-m buffers around each structure. c The malaria incidence per target area is generated using the estimated population and nearest facility incidence. d Target areas are ranked with final inclusion/exclusion based on local knowledge
