*Gray shading signifies a negative result with both the pan-pLDH and pfHRP2 antigen tests on the RDT. Africa indicates unknown country of origin. ID, identification; NA, not applicable; pan, pan–Plasmodium spp.; Pf, P. falciparum; pfHRP2, Plasmodium falciparum histidine-rich protein 2; pLDH, Plasmodium lactate dehydrogenase; RDT, rapid diagnostic test. †0–4 result scored by World Health Organization guidelines. ‡Sample results matched outcomes using CareStart Malaria RDT, whereas parasites were not detected by BinaxNOW RDT (Appendix Figures 2, 3).
