A 100 × 100 m human population density map developed from fine resolution satellite imagery, land cover and available information on human population counts from the highest resolution census administration boundaries showing the catchment areas around each hospital [47,48]. Graph panels show monthly cases of malaria admissions observed (black bars) and imputed (gray bars) across the 11-year period.
