Prevalence of pfhrp2 among the clonal lineages identified in Iquitos.

Clinical samples were collected in 1998–2001 (N = 92) and 2003–2005 (N = 96). Dark grey boxes represent the proportion of pfhrp2-positive samples while light grey boxes represent pfhrp2-negative isolates. The clonal lineage assignments are indicated along the x-axis.
