Spatial distribution of<em> Falciparum</em> malaria infections in Zanzibar: implications for focal drug administration strategies targeting... (Publications)
Background.: Optimal use of mass/targeted screen-and-treat or mass or focal drug administration as malaria elimination strategies remains unclear. We therefore studied spatial distribution of Plasmodium
Mosquito behavior change after distribution of bednets results in decreased protection against malaria exposure (Publications)
efficacy of vector control in reducing malaria transmission. Methods.: In this study, we quantified human exposure to both bites and infective bites of a major malaria vector in Papua New Guinea over the [...] the course of 4 years surrounding nationwide bednet distribution. We also quantified malaria infection prevalence in the human population during the same time period. Results.: We observed a shift in mosquito [...] period and was lowest in the adult population, who may be an important...
Asymptomatic and sub-microscopic malaria infection in Kayah State, eastern Myanmar (Publications)
be targeted for malaria elimination. METHODS: A mass blood survey was conducted among 485 individuals from six villages in Kayah State, an area of endemic but low transmission malaria in eastern Myanmar [...] BACKGROUND: Myanmar has the heaviest burden of malaria in the Greater Mekong Sub-region. Asymptomatic Plasmodium spp. infections are common in this region and may represent an important reservoir of t [...] Myanmar. Malaria infection was screened by rapid diagnostic test (RDT), light...
Nouvelles approches pour la prévention de la malaria chez le voyageur (Publications)
Malaria is declining in many tropical countries. This reduction challenges our usual preventive strategies. In moderate to low risk areas, the Swiss guidelines recommend a stand-by emergency treatment [...] making through three clinical studies. The first showed that travelers visiting moderate to low risk malaria areas prefer a standby emergency treatment rather than chemoprophylaxis. The second study investigates
Sensitive and accurate quantification of human malaria parasites using droplet digital PCR (ddPCR) (Publications)
of parasite density in the human host is essential for understanding the biology and pathology of malaria. Semi-quantitative molecular methods are widely applied, but the need for an external standard curve
Gametocyte carriage in uncomplicated <em>Plasmodium falciparum</em> malaria following treatment with artemisinin combination therapy: a systematic... (Publications)
BACKGROUND: Gametocytes are responsible for transmission of malaria from human to mosquito. Artemisinin combination therapy (ACT) reduces post-treatment gametocyte carriage, dependent upon host, parasite [...] pharmacodynamic factors. The gametocytocidal properties of antimalarial drugs are important for malaria elimination efforts. An individual patient clinical data meta-analysis was undertaken to identify
Malaria vectors and their blood-meal sources in an area of high bed net ownership in the western Kenya highlands (Publications)
BACKGROUND: Blood-meal sources of malaria vectors affect their capacity to transmit the disease. Most efficient malaria vectors prefer human hosts. However, with increasing personal protection measures [...] measures it becomes more difficult for them to find human hosts. Here recent malaria vector blood-meal sources in western Kenya highlands were investigated. METHODS: Adult mosquitoes resting indoors, outdoors [...] domesticated animals and 83.6 % had people sharing houses with livestock at...
Asymptomatic only at first sight: malaria infection among schoolchildren in highland Rwanda (Publications)
BACKGROUND: Plasmodium infection and malaria in school children are increasingly recognized as a relevant public health problem, but data on actual prevalence and health consequences are insufficient. [...] district of Rwanda, 1089 children aged 6-10 years were clinically and anthropometrically examined, malaria parasites were diagnosed by microscopy and PCR, haemoglobin concentrations were measured, and so [...] exception of underweight, these conditions were also increased at submicroscopic...
Haemoglobin changes and risk of anaemia following treatment for uncomplicated falciparum malaria in sub-Saharan Africa (Publications)
BACKGROUND: Anaemia is common in malaria. It is important to quantitate the risk of anaemia and to distinguish factors related to the natural history of disease from potential drug toxicity. METHODS: [...] data analysis based on nine randomized controlled trials of treatments of uncomplicated falciparum malaria from 13 sub-Saharan African countries. Risk factors for reduced haemoglobin (Hb) concentrations and
Natural immune response to <em>Plasmodium vivax </em>alpha-helical coiled coil protein motifs and its association with the risk of <em>P. vivax</em>... (Publications)
selected coiled coil antigens might be good markers of both exposure and acquired immunity to P. vivax malaria, and further preclinical investigation should be performed to determine their potential as P. vivax
