Plasmodium falciparum histidine rich protein-2 diversity and the implications for PfHRP 2: based malaria rapid diagnostic tests in Ghana

Abstract

A high number of P. falciparum parasites, which lack pfhrp2 exon 2 gene have been identified in two communities in Ghana. Continuous nationwide monitoring of the prevalence of pfhrp2 deletant parasites would be essential to malaria control. The use of RDT kits that are effective at malaria diagnosis despite deletion of pfhrp2, such as the PfHRP-2/PfLDH combo RDT kit could enhance the diagnosis of clinical malaria in Ghana.
