Ensuring quality and access for malaria diagnosis: how can it be achieved?
TL;DR: In achieving this goal, the shift from symptom-based diagnosis to parasite-based management of malaria can bring significant improvements to tropical fever management, rather than represent a further burden on poor, malaria-endemic populations and their overstretched health services.
Journal ArticleDOI
Genetic Diversity of Plasmodium falciparum Histidine-Rich Protein 2 (PfHRP2) and Its Effect on the Performance of PfHRP2-Based Rapid Diagnostic Tests
Joanne Baker,James S. McCarthy,Michelle L. Gatton,Dennis E. Kyle,Vicente Y. Belizario,Jennifer Luchavez,David Bell,Qin Cheng +7 more
TL;DR: The genetic diversity of PfHRP2, which includes numerous amino acid repeats, is examined to provide an alternative explanation for the variable sensitivity in field tests of malaria RDTs that is not due to the quality of the RDT
Journal ArticleDOI

TL;DR: In this paper, a decision tree model and probabilistic sensitivity analysis applied to outpatients presenting at rural health facilities with suspected malaria was used to evaluate the relative cost-effectiveness in different sub-Saharan African settings of presumptive treatment, field standard microscopy and rapid diagnostic tests (RDTs) to diagnose malaria.
