Fig. 3From: Spatial–temporal clustering of malaria using routinely collected health facility data on the Kenyan CoastSpatial pattern of annual malaria RDT positivity rate by enumeration zones and spatial hotspots of fever test positive cases. 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 in Chasimba health centre and clusters 2—9 are the secondary hotspots located in Ziani (clusters 2 and 3), Kadzinuni (clusters 4 and 8) and Bomani (cluster 6) dispensaries. The additional secondary clusters 5, 7 and 9 were located in Chasimba health centreBack to article page
