The Search for Plasmodium falciparum histidine–rich protein 2/3 Deletions in Zambia and Implications for Plasmodium falciparum histidine-rich protein 2-Based Rapid Diagnostic Tests

We attempted to identify Plasmodium falciparum histidine–rich protein 2/3 (pfhrp2/3) deletions among rapid diagnostic test (RDT)–negative but PCR- or microscopy-positive P. falciparum–infected individuals in areas of low transmission (Choma District, 2009–2011) and high transmission (Nchelenge District, 2015–2017) in Zambia. Through community-based surveys, 5,167 participants were screened at 1,147 households by P. falciparum histidine-rich...
