Fig. 3

The distribution of PfRh5 YH and HD haplotypes in Kilifi County in the east of Kenya by the Indian Ocean. The map highlights the Kilifi health and demographic surveillance system (KHDSS). a The distribution of YH and HD haplotypes in all three malaria infection populations (uncomplicated, asymptomatic, complicated) between 2007 and 2009. The years are represented by different symbols, triangle for 2007, circle for 2008 and square for 2009. b YH and HD haplotype distribution in 2007 showing a significant cluster (depicted by the red circle showing the region of the cluster) in the north of the KHDSS that contains more YH alleles compared to the parasites from the south (relative risk = 2, p = 0.0024) using the SaTScan software. c YH and HD allele distribution in 2008; and, d YH and HD haplotype distribution in 2009. The black cross indicates the health centres Kilifi District Hospital, Junju and Pingilikani dispensaries. The alleles are depicted as blue for HD and red for YH
