Estimating the duration of Plasmodium falciparum infection from trials of indoor residual spraying (Publications)
cross-sectional survey data collected from three historical trials of indoor residual spraying against malaria: one from two contiguous districts in Tanzania-Kenya (Pare Taveta) carried out in 1954, the others [...] showed considerable variation but no general age trend. There was also no clear relationship between malaria endemicity and infection duration. Analyses of successive sampling from the same individuals with [...] areas. Periods of several years may be required to evaluate long-term...
The influence of zinc supplementation on morbidity due to <em>Plasmodium falciparum</em>: a randomized trial in preschool children in Papua New Guinea (Publications)
determine the influence of zinc on malaria morbidity we conducted a randomized placebo-controlled trial of daily zinc supplementation in children residing in a malaria endemic region of Papua New Guinea [...] mg elemental zinc (n = 136) or placebo (n = 138) for 6 days a week for 46 weeks. Slide-confirmed malaria episodes were detected by surveillance of cases self-reporting to a local health center. Cross-sectional
Case studies in public-private-partnership in health with the focus of enhancing the accessibility of health interventions (Publications)
level NGO consortium with a focus on malaria and the second one is an international advocacy group with an overarching goal of protecting children against malaria through an innovative mechanism. The case [...] case study approach is used to analyze why the PPP approach was used to address malaria control and how it was implemented. Both PPPs demonstrated that relationships between the public and private sector
Clonal expansion of artemisinin-resistant <em>Plasmodium falciparum</em> in Uganda is associated with substandard treatment practices (Publications)
the frame of the Community Access to Rectal Artesunate for Malaria project, blood samples were collected from children with signs of severe malaria before and after RAS implementation. K13 polymorphisms were [...] a driver of this recent emergence. Rectal artesunate (RAS) as pre-referral treatment for severe malaria in children was implemented in 2019 in Northern Uganda. The objective of this study was to determine
Evaluation of anopheline diversity and abundance across outdoor collection schemes utilizing cdc light traps in Nchelenge District, Zambia (Publications)
In the global fight against malaria, standard vector control methods such as indoor residual spraying (IRS) and insecticide-treated nets (ITNs) are intended to protect inside residential structures and [...] may be exposed to outdoors. Nchelenge District in northern Zambia experiences persistently high malaria transmission even with ITNs and IRS in place. However, very few studies have examined outdoor vector [...] including a number of infectious An. funestus, may partially explain the...

Imaging of <em>Plasmodium</em> liver stages to drive next-generation antimalarial drug discovery (Publications)
Most malaria drug development focuses on parasite stages detected in red blood cells, even though to achieve eradication, next-generation drugs active against both erythrocytic and exo-erythrocytic forms [...] imidazolopiperazine confers complete causal prophylactic protection (15 mg/kg) in rodent models of malaria and shows potent in vivo blood-stage therapeutic activity. The open source chemical tools resulting
The epidemiology of multiple <em>Plasmodium falciparum</em> infections. 7. Dynamics of multiple <em>Plasmodium falciparum </em>infections in infants... (Publications)
The force of infection and recovery rate for malaria in infants in a highly endemic area of Tanzania were analysed using polymerase chain reaction-restriction fragment length polymorphism genotyping of [...] recovery rates were in children under 4 months of age. The higher susceptibility of infants to clinical malaria in comparison with older children, in areas of very high transmission, may be largely a consequence

For the directed optimization of these activities, an investigation of the mode of action [...] their pharmacological potential as a valuable lead structure against the widespread tropical disease malaria
Discovery and characterization of ACT-451840: an antimalarial drug with a novel mechanism of action (Publications)
More than 40 % of the world's population is at risk of being infected with malaria. Most malaria cases occur in the countries of sub-Saharan Africa, Central and South America, and Asia. Resistance to standard
