Revisiting the effect of pharmaceuticals on transmission stage formation in the malaria parasite <em>Plasmodium falciparum</em> (Publications)
Malaria parasites rely on specialized stages, called gametocytes, to ensure human-to-human transmission. The formation of these sexual precursor cells is initiated by commitment of blood stage parasites [...] vivo. These observations suggest that therapeutic interventions may promote gametocytogenesis and malaria transmission. Here, we engineered a P. falciparum reporter line to quantify sexual commitment rates [...] rates after exposure to antimalarials and other pharmaceuticals commonly...
Multi-insecticide resistant malaria vectors in the field remain susceptible to malathion, despite the presence of <em>Ace1</em> point mutations (Publications)
Insecticide resistance in Anopheles mosquitoes is seriously threatening the success of insecticide-based malaria vector control. Surveillance of insecticide resistance in mosquito populations and identifying the
<em>Plasmodium falciparum</em> parasite prevalence in East Africa: updating data for malaria stratification (Publications)
Burden High Impact (HBHI) strategy for malaria encourages countries to use multiple sources of available data to define the sub-national vulnerabilities to malaria risk, including parasite prevalence. Here [...] to provide a more contemporary understanding of the sub-national malaria prevalence stratification across the sub-region for 2019. Malaria prevalence data from surveys undertaken between January 2010 and
Detection of asymptomatic malaria in Asian countries: a meta-analysis of diagnostic accuracy (Publications)
Background: Achieving malaria elimination requires the targeting of the human reservoir of infection, including those patients with asymptomatic infection. The objective was to synthesise evidence on the [...] accuracy of the rapid- onsite diagnostic tests (RDTs) and microscopy for the detection of asymptomatic malaria as part of the surveillance activities in Asian countries. Methods: This was a meta-analysis of [...] that evaluated the diagnostic per- formance of RDTs and microscopy for...
Multi-dose priming regimens of PfSPZ vaccine: safety and efficacy against controlled human malaria infection in Equatoguinean adults (Publications)
Tolerability, safety, immunogenicity, and vaccine efficacy (VE) against homologous-controlled human malaria infection (CHMI) 6-7 weeks after vaccination were assessed to down-select the best regimen. All four
Leveraging mathematical models of disease dynamics and machine learning to improve development of novel malaria interventions (Publications)
targeted reductions in malaria prevalence. METHODS: A mathematical model of malaria transmission dynamics is used to simulate deployment and predict potential impact of new malaria interventions by considering [...] mathematical models of malaria dynamics coupled with machine learning. Our analysis identifies requirements of efficacy, coverage, and duration of effect for five novel malaria interventions to achieve [...] achieve specified health goals. RESULTS: We apply our approach to five malar...
Rethinking human resources and capacity building needs for malaria control and elimination in Africa (Publications)
considerable success in controlling malaria worldwide, progress toward achieving malaria elimination has largely stalled. In particular, strategies to overcome roadblocks in malaria control and elimination in Africa [...] Africa are critical to achieving worldwide malaria elimination goals—this continent carries 94% of the global malaria case burden. To identify key areas for targeted efforts, we combined a comprehensive [...] ve review of current literature with direct feedback gathered from...
