Article Synopsis
  • The study focuses on the role of asymptomatic malaria carriers in sustaining transmission and compares the effectiveness of two different diagnostic tests (uRDT and cRDT) for detecting asymptomatic malaria in Ghana over a year.
  • Researchers tested 4,000 participants in two towns, and through mass testing and treatment initiatives, they tracked the impact on malaria prevalence.
  • Results showed that while the intervention site saw a significant decrease in asymptomatic parasite prevalence, the control site did not experience a notable change, and the models indicated the impact of diagnosis sensitivity and human movement on the effectiveness of the interventions.

Reports of increasing false-negative HRP2-based rapid diagnostic test results across Africa require constant monitoring of factors associated with these false-negative outcomes, as failure of this diagnostic tool will have severe consequences on malaria treatment and control programs. This study characterized the extent of genetic diversity in the Plasmodium falciparum histidine-rich protein 2 (Pfhrp2) gene in P. falciparum isolates from symptomatic malaria patients across the regions of Ghana.

Background: Clinical presentations of malaria in Ghana are primarily caused by infections containing microscopic densities of Plasmodium falciparum, with a minor contribution from Plasmodium malariae and Plasmodium ovale. However, infections containing submicroscopic parasite densities can result in clinical disease. In this study, we used PCR to determine the prevalence of three human malaria parasite species harboured by suspected malaria patients attending healthcare facilities across the country.

Introduction: The global effort to eradicate malaria requires a drastic measure to terminate relapse from hypnozoites as well as transmission via gametocytes in malaria-endemic areas. Primaquine has been recommended for the treatment of P. falciparum gametocytes and P.

Background: Monitoring changes in the composition of the species circulating within the population over a period can inform appropriate treatment recommendations. This study monitored variations in the prevalence of four common human species carried by children with asymptomatic malaria infections over a two-year period.

Methods: Two cross-sectional studies were conducted in November 2017 and December 2019.

Background: The Alere™ Malaria Ag P.f Ultra-sensitive RDT (UsmRDT) kit is an HRP2-based malaria rapid diagnostic test (RDT) with enhanced sensitivity relative to the SD Bioline Malaria Ag P.f RDT (mRDT) kit.

Background: The ABO and the Rhesus blood group systems, as well as various abnormal haemoglobin (Hb) variants (haemoglobinopathies) are known to influence malaria parasite carriage and disease severity in individuals living in malaria endemic areas. This study identified the blood group and Hb variant distribution and Plasmodium falciparum infection status of afebrile individuals living in southern Ghana.

Methods: Afebrile participants were recruited from Obom (358) in the Greater Accra Region and Ewim (100) and Simiw (329) in the Central Region of Ghana.
