Transmission dynamics of Plasmodium vivax haplotypes and haplogroups in San Carlos community. Panel A : Monthly distribution of the 162 P. vivax haplotypes found among 164 P. vivax infections (patent and sub-patent) between April 2008 and June 2010. Twenty unique haplotypes were detected and are represented by different colours. Panel B : Monthly distribution of the haplogroups containing closely related haplotypes determined using eBURST. Composition of each haplogroup: A (H1, H2, H3, H6, H12, H13, H14, H15, H16, H19), B (H17, H20), C (H4, H5), D (H9, H10, H11), singletons (H7, H8, H18).
