GDV1 induces sexual commitment of malaria parasites by antagonizing HP1-dependent gene silencing (Publications)
Malaria is caused by Plasmodium parasites that proliferate in the bloodstream. During each replication cycle, some parasites differentiate into gametocytes, the only forms able to infect the mosquito vector [...] vector and transmit malaria. Sexual commitment is triggered by activation of AP2-G, the master transcriptional regulator of gametocytogenesis. Heterochromatin protein 1 (HP1)-dependent silencing of ap2-g
Drug use in the management of uncomplicated malaria in public health facilities in the Democratic Republic of the Congo (Publications)
BACKGROUND: Malaria the first causes of death from parasitic infection worldwide. Interventions to reduce the burden of malaria have produced a tremendous drop in malaria morbidity and mortality. However [...] performed. RESULTS: A total of 2300 files out of 3300 (69.7%) concerned uncomplicated malaria and were included in analysis. Malaria treatment was initiated after a positive RDT or microscopy in 51.5% of cases [...] However, progress is slower in DRC, which shares with Nigeria 39% of...
Malaria infection in mosquitoes decreases the personal protection offered by permethrin-treated bednets (Publications)
BACKGROUND: Insecticides targeting adult mosquitoes are the main way of controlling malaria. They work not only by killing mosquitoes, but also by repelling and irritating them. Indeed their repellent [...] repellent action gives valuable personal protection against biting mosquitoes. In the context of malaria control this personal protection is especially relevant when mosquitoes are infectious, whereas to protect [...] not yet infectious are killed (so, not repelled) by the insecticide. As the...
Infant and child mortality in relation to malaria transmission in KEMRI/CDC HDSS, Western Kenya: validation of verbal autopsy (Publications)
(VA) is widely used for estimating malaria specific mortality rates, but does not reliably distinguish malaria from other febrile illnesses. Overall malaria attributable mortality includes both direct and [...] both all-cause and malaria-specific mortality. 48.2% of the deaths could be attributed to malaria by analysing the exposure-response relationship, though only 20.5% of VAs assigned malaria as the cause and [...] BACKGROUND: Malaria transmission reduction is a goal of many malaria control...
Assessing the variability in experimental hut trials evaluating insecticide-treated nets against malaria vectors (Publications)
Experimental hut trials (EHTs) are used to evaluate indoor vector control interventions against malaria vectors in a controlled setting. The level of variability present in the assay will influence whether
Species composition and insecticide resistance in malaria vectors in Ellibou, southern Côte d’Ivoire and first finding of <em>Anopheles... (Publications)
status of the target vector population is important to guide malaria vector control. The aim of this study was to characterize the malaria vector population in terms of species composition, insecticide [...] an early warning sign, as An. arabiensis shows a different biology than the currently documented malaria vectors. Because the local An. gambiae population was still susceptible to malathion, upregulation
The relative effect of climate variability on malaria incidence after scale-up of interventions in western Kenya: a time-series analysis of monthly... (Publications)
effect of climate variability on malaria incidence after scale-up of interventions in western Kenya. Methods Bayesian negative binomial models were fitted to monthly malaria incidence data, extracted from [...] variable selection was used to determine the elapsing time between climate suitability and malaria incidence. Results Malaria incidence increased by 50% from 2008 to 2010, then declined by 73% until 2015. There [...] associated with a decline in malaria incidence in children aged 6–59...
Modelling to inform next-generation medical interventions for malaria prevention and treatment (Publications)
Global progress against malaria has stagnated and novel medical interventions to prevent malaria are needed to fill gaps in existing tools and improve protection against infection and disease. Candidate [...] opportunity to link product characteristics with expected public health outcomes. Population models of malaria transmission can provide a better understanding of which, and at what magnitude, key intervention [...] deployment strategies. We describe how modelling evidence can guide and...
What Africa can do to accelerate and sustain progress against malaria (Publications)
weaknesses in the fight against malaria and instead reinforces a narrow, commodity-driven vision of disease control. This paper therefore describes the core challenges hindering malaria programs in Africa and [...] After a longstanding global presence, malaria is now largely non-existent or suppressed in most parts of the world. Today, cases and deaths are primarily concentrated in sub-Saharan Africa. According to [...] opportunities to rethink current strategies for sustainable control and...
