Spatial pattern of annual malaria RDT positivity rate by enumeration zones and spatial hotspots of fever test positive cases stratified into quarterly monthly periods. The red shading in the choropleth map indicates very high TPR (≥ 60%), brown indicated high TPR (40–59%), dark green is low-moderate TPR regions (20–39%) and light green shading indicating lower TPR (< 20%). The large black circles indicate the location of high-risk clusters detected by purely spatial scan statistics using geographic coordinates of the centroid of each EZ. Cluster 1 indicates the primary cluster located and clusters 2–7 are the secondary hotspots
