The duration of chemoprophylaxis against malaria after treatment with artesunate-amodiaquine and artemether-lumefantrine and the effects of <em>pfmdr1... (Publications)
BACKGROUND: The majority of Plasmodium falciparum malaria cases in Africa are treated with the artemisinin combination therapies artemether-lumefantrine (AL) and artesunate-amodiaquine (AS-AQ), with a [...] amodiaquine being also widely used as part of seasonal malaria chemoprevention programs combined with sulfadoxine-pyrimethamine. While artemisinin derivatives have a short half-life, lumefantrine and a [...] reinfection. The estimated duration of chemoprophylaxis was then used in a...
Methodological framework for assessing malaria risk associated with climate change in Côte d'Ivoire (Publications)
Malaria is the leading cause of morbidity among children under five years of age and pregnant women in Côte d'Ivoire. We assessed the geographical distribution of its risk in all climatic zones of the [...] main driving components affecting the risk: Hazard, exposure and vulnerability. Considering the malaria impact chain, various variables were identified for each of the risk factors and for each variable [...] or equatorial (tropical transition regime) in the North and the mountainous (humid)...
A review of selective indoor residual spraying for malaria control (Publications)
BACKGROUND: Indoor residual spraying (IRS) is one of the most effective malaria control tools. However, its application has become limited to specific contexts due to the increased costs of IRS products [...] tive spray targeted to particular areas/surfaces of dwellings-has been proposed to maintain the malaria control and resistance-management benefits of IRS while decreasing the costs of the intervention [...] mosquitoes and (2) studies that evaluated the impact of selective spraying on...
Slow clearance of histidine-rich protein-2 in Gabonese with uncomplicated malaria (Publications)
Malaria rapid diagnostic tests (RDTs), which detect Plasmodium falciparum (Pf)-specific histidine-rich protein-2 (HRP2), have increasing importance for the diagnosis and control of malaria, especially [...] RDT-based assessment following a malaria treatment for weeks. A better understanding of the HRP2 clearance dynamics is critical for guiding the diagnosis of malaria when relying on RDTs. IMPORTANCE: Detecting [...] determine the long-term kinetic of HRP2-levels in peripheral blood after...
The impact of soil transmitted helminth on malaria clinical presentation and treatment outcome: a case control study among children in Bagamoyo... (Publications)
been documented between Plasmodium and STH. This study investigated the impact of STH on clinical malaria presentation and treatment outcome. METHODS: A matched case control study with a semi longitudinal [...] areas of Bagamoyo, coastal region of Tanzania. Cases were children with uncomplicated and severe malaria enrolled from the health facilities while controls were children with asymptomatic Plasmodium parasitemia [...] regression analysis there was a tendency for a protective effect of STH...
The effects of climatic and non-climatic factors on malaria mortality at different spatial scales in western Kenya, 2008-2019 (Publications)
relatively small size of the HDSS, there was spatial variation in malaria mortality that peaked every May-June. The rapid decline in malaria mortality was associated with bed nets, and finer spatial scale [...] BACKGROUND: Malaria mortality is influenced by several factors including climatic and environmental factors, interventions, socioeconomic status (SES) and access to health systems. Here, we investigated [...] ed the joint effects of climatic and non-climatic factors on under-five malaria...
Potential impact of climatic factors on malaria in Rwanda between 2012 and 2021: a time-series analysis (Publications)

Addressing this critical gap, this study analyses how climatic factors influence malaria transmission [...] BACKGROUND: Malaria remains an important public health problem, particularly in sub-Saharan Africa. In Rwanda, where malaria ranks among the leading causes of mortality and morbidity, disease transmission [...] temperature and cumulative rainfall on malaria incidence in Rwanda from...
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...
