1. Background

  • Over two-thirds of all malaria diagnoses in Africa are made using rapid diagnostic tests that detect histidine rich protein 2 (HRP2).1
  • A recently described deletion mutation of the P. falciparum histidine-rich protein 2 and/or 3 (pfhrp2/3) genes allows it to escape detection by common rapid diagnostic tests (RDTs).2, 3
  • Increasing reports from Africa indicate that parasites with this mutation are common in select locations.4
  • We previously found a 6.4% national prevalence of pfhrp2-negative parasites among asymptomatic children in the DRC.5
  • Initial hypothesis: Pfhrp2-deleted parasites are responsible for missed clinical cases of falciparum malaria in the DRC.
