MOESM4 of Malaria hotspots defined by clinical malaria, asymptomatic carriage, PCR and vector numbers in a low transmission area on the Kenyan Coast

Additional file 4. Overlapping of malaria transmission hotspots detected in 2012 with those detected in 2013. Empty cells indicates no intersection and no overlapping was observed i.e. d > R + r. A ratio = 1 indicates a total overlapping i.e. d = 0 and R = r, or d < R - r, where d is the distance between the centres of two given hotspots, R and r the radii of these hotspots. HS index hotspot index in relation to Additional file 8.
