Closing this gap will enable monitoring the spread of drug resistance, classifying infections as local or imported, and distinguishing reinfection, recrudescence, and relapse. To achieve these objectives, microhaplotype marker panels that allow powerful genotyping of polyclonal infections are needed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We designed a globally applicable amplicon panel for P. vivax (PvGAP), selecting targets based on both genetic diversity and distance to maximize discriminatory capability between geographic regions.
