Fig. 2

Spatial distribution of smoothed mean TPR across 12 months of surveillance at homesteads level aggregated at 1 km radius and the spatial hotspots of fever positive RDT cases, analysed without smoothing. Each plotted point represents an individual homestead, where red shading indicates high TPR and green shading indicates lower TPR. The large black circles indicate the significant hotspots (analysed without smoothing) where 1 indicates the primary cluster located in Chasimba health centre and clusters 2–9 are the secondary hotspots located in Ziani, Kadzinuni, Bomani and Jaribuni dispensaries
