  1. A much higher infection prevalence was detected by qPCR than by RDT
  2. Plasmodium vivax and P. falciparum were detected in similar numbers (Pv: n = 16, Pf: n = 21, Mixed: n = 5)
  3. Infections were highly clustered, with 64% occurring in the Khumi and Mro groups (27/42)
  4. No infections were detected among Bengalis (0/100)
