Spatial high (red lines) and low (blue lines) risk clusters for malaria infection in Phi (2016). The amount of Plasmodium infections within each household is displayed by a size and colour gradient, with circles indicating field houses and triangles indicating village houses. The large solid red line borders a Plasmodium hotspot in the field (red soil area), which is equivalent to the P. malariae cluster (Cluster 1 in Table 2). The upper small solid red line borders a P. vivax hotspot in the red soil area (Cluster 2 in Table 2), whereas the lower small solid red line borders a P. malariae hotspot in the village (Cluster 5 in Table 2). The large solid blue line indicates a coldspot for P. malariae along the road to the red soil area (Cluster 4 in Table 2). The small solid blue line borders a coldspot for P. vivax in the red soil area (Cluster 3 in Table 2)
