Probing <em>Plasmodium falciparum</em> sexual commitment at the single-cell level (Publications)
Background: Malaria parasites go through major transitions during their complex life cycle, yet the underlying differentiation pathways remain obscure. Here we apply single cell transcriptomics to unravel [...] programs, with important implications for our understanding of parasite biology and the ongoing malaria elimination campaign.
Assessing whether universal coverage with insecticide-treated nets has been achieved: is the right indicator being used? (Publications)
(ITNs) are the primary tool for malaria vector control in sub-Saharan Africa, and have been responsible for an estimated two-thirds of the reduction in the global burden of malaria in recent years. While the [...] ITN for 2 people did not exceed 60% at the national level in any survey, except in Uganda's 2014 Malaria Indicator Survey (MIS). At 80% population ITN access, the expected proportion of households with [...] success of an ITN distribution programme. Under current ITN distribution...
Association between the proportion of <em>Plasmodium falciparum</em> and <em>Plasmodium vivax</em> infections detected by passive surveillance and the... (Publications)
proportion of infections detected in routine malaria data, P(Detect), was derived from paired household cross-sectional survey and routinely collected malaria data within health facilities. P(Detect) was [...] BACKGROUND: Passively collected malaria case data are the foundation for public health decision making. However, because of population-level immunity, infections might not always be sufficiently symptomatic [...] model in 431 clusters spanning the Americas, Africa, and Asia. The...

unknown. An increase in risk of Plasmodium vivax malaria in early childhood resulting in a cross-species protection against severe P. falciparum malaria has been proposed as a possible mechanism in Melanesian [...] wild-type allele. No significant differences in the incidence of P. falciparum (Pf) or P. vivax (Pv) malaria were observed between alpha(+)-thalassemia homozygote (Pf: Incidence rate ratio (IRR) = 1.13, CI(95) [...] = 0.008). This study therefore failed to confirm an increased risk of...
Ultra-sensitive detection of <em>Plasmodium falciparum</em> by amplification of multi-copy subtelomeric targets (Publications)
qPCR in community surveillance and for monitoring interventions to better describe malaria epidemiology and inform malaria elimination efforts [...] BACKGROUND: Planning and evaluating malaria control strategies relies on accurate definition of parasite prevalence in the population. A large proportion of asymptomatic parasite infections can only be [...] might still remain undetected when absent in the limited blood volume sampled. CONCLUSIONS: Measured malaria prevalence in communities is...

Population pharmacokinetics of the antimalarial amodiaquine: a pooled analysis to optimize dosing (Publications)
Amodiaquine plus artesunate is the recommended antimalarial treatment in many malaria-endemic countries. However, pediatric doses are largely based on a linear extrapolation from adult doses. We pooled [...] amodiaquine, to optimize the dose across all age groups. Adults and children with uncomplicated malaria received daily weight-based doses of amodiaquine or artesunate-amodiaquine over three days. Plasma [...] 22.4% (15.6 - 31.9%) lower at the start of treatment than during convalescence,...
