Public health impact and cost-effectiveness of the RTS,S/AS01 malaria vaccine: a systematic comparison of predictions from four mathematical models (Publications)
BACKGROUND: The phase 3 trial of the RTS,S/AS01 malaria vaccine candidate showed modest efficacy of the vaccine against Plasmodium falciparum malaria, but was not powered to assess mortality endpoints [...] settings. Decisions about implementation will need to consider levels of malaria burden, the cost-effectiveness and coverage of other malaria interventions, health priorities, financing, and the capacity of the [...] iveness of routine use of the RTS,S/AS01 vaccine in African settings....
Immuno-gold silver staining assays on capillary-driven microfluidics for the detection of malaria antigens (Publications)
a lack of highly sensitive malaria RDTs that can detect low antigen concentration at the onset of infection. Here, we present a strategy to improve the sensitivity of malaria RDTs by using capillary-driven [...] al to the concentration of antigen in a sample. We illustrate this method using the recombinant malaria antigen Plasmodium falciparum histidine-rich-protein 2 (rPfHRP2) spiked in human serum. This antigen [...] min, which is approaching the desired sensitivity needed in the Target...
Hemozoin-catalyzed precipitation polymerization as an assay for malaria diagnosis (Publications)
Methods to diagnose malaria are of paramount interest to eradicate the disease. Current methods have severe limitations, as they are either costly or not sensitive enough to detect low levels of parasitemia [...] increase is proportional to the concentration of hemozoin, with a detection limit of 0.85 ng mL(-1). Malaria parasites in human blood can be detected down to 10 infected red blood cells muL(-1). The assay could
High cure rates and tolerability of artesunate-amodiaquine and dihydroartemisinin-piperaquine for the treatment of uncomplicated falciparum malaria in... (Publications)
BACKGROUND: The Tanzanian National Malaria Control Programme (NMCP) and its partners have been implementing regular therapeutic efficacy studies (TES) to monitor the performance of different drugs used [...] mefantrine, which is the first-line anti-malarial for the treatment of uncomplicated falciparum malaria. Data on the performance of other artemisinin-based combinations is urgently needed to support timely [...] parasitological responses of ASAQ and DP for directly observed treatment of...
Mosquito repellents for malaria prevention (Review) (Publications)
BACKGROUND: Malaria is an important cause of illness and death across endemic regions. Considerable success against malaria has been achieved within the past decade mainly through long-lasting insecti [...] alone. It is unclear if topical repellents can prevent clinical malaria (RR 0.65, 95% CI 0.4 to 1.07, very low certainty evidence) or malaria infection (RR 0.84, 95% CI 0.64 to 1.12, low-certainty evidence) [...] repellentsTwo cluster-randomized RCTs investigated mosquito coils for malaria...
Performance of antigen concentration thresholds for attributing fever to malaria among outpatients in Angola (Publications)
The density of malaria parasites is a key determinant in whether or not an infected individual develops fever. While the pyrogenic threshold for malaria parasite density has been well-studied, there is [...] latent-class modeling to attribute malaria etiology to the fevers and to estimate the sensitivity and specificity of different antigen thresholds for detecting malaria fevers. Amongst patients positive [...] febrile HRP2+ patients compared to afebrile HRP2+ patients. When considering HRP2...
Antagonistic effects of <em>Plasmodium</em>-helminth co-infections on malaria pathology in different population groups in Côte d'Ivoire (Publications)
INTRODUCTION: Plasmodium spp. and helminths are co-endemic in many parts of the tropics; hence, co-infection is a common phenomenon. Interactions between Plasmodium and helminth infections may alter t
Measuring and characterizing night time human behaviour as it relates to residual malaria transmission in sub-Saharan Africa: a review of the... (Publications)

Among studies that quantified human-vector [...] BACKGROUND: Malaria cases and deaths decreased dramatically in recent years, largely due to effective vector control interventions. Persistence of transmission after good coverage has been achieved with [...] , namely insecticide-treated nets or indoor residual spraying, poses a...
