Study flowchart. Thirty-seven participants were enrolled and treated (CQ + PQ) on D0. Twenty-eight participants had at least one recurrence and nine participants had no recurrences after treatment. Only samples positive for P. vivax by ssPCR were genotyped with 15 microsatellites (MS). In total, 162 haplotypes were detected in monoclonal and polyclonal P. vivax samples. From 28 polyclonal infections only 37 haplotypes were identified as described in the Methods section. * = microscopically positive. Pv = P. vivax.
