Relapsing malaria caused by Plasmodium vivax parasites poses a significant challenge to global malaria elimination efforts. About one third of the population remains at risk of contracting P. vivax malaria, and 85% of P. vivax infections stem from reactivated latent parasites, leading to chronic ana...emia and increased morbidity and mortality. In addition to diagnostic tools that can detect the acute, blood-stage of P. vivax, new tools are needed to detect the dormant infections before they reactivate and contribute to morbidity and onwards transmission

2nd edition. The purpose of this document is to present updated standardized protocols that P. falciparum-endemic countries can use to determine the prevalence of parasites with pfhrp2/3 gene deletions causing negative HRP2 RDT results among symptomatic falciparum patients. The findings should be us...ed to guide RDT selection; more specifically when to shift away from exclusive use of HRP2 to detect P. falciparum infections.
