  1. Px: patient; na: not applicable; AI: asymptomatic infection; UA: data unavailable.
  2. aParasite density cannot be calculated; PCR results were obtained from post-mortem tissue.
  3. bPatient was initially diagnosed with P. falciparum by the OptiMAL-IT Rapid test.
  4. cPatient reported a previous malaria infection in the DRC; received artequine as treatment.
  5. dDates corresponds to thin/thick blood smears results for patient 1–5 and PCR results for patients 6-12.
  6. eNo of asexual parasites/μl of blood.
  7. fCQ resistance type in the pfcrt gene: CVMNK (wild type); CVIET (CQ resistant).
  8. gSequencing results showed a major peak for CVIET and minor peak for CVMNK when retested.
