protection against P. vivax malaria by a mechanism that is independent of the Duffy antigen. P. vivax malaria may have contributed to shaping the unique host genetic adaptations to malaria in Asian and Oceanic [...] a 27-base pair deletion in the erythrocyte band 3 gene, SLC4A1Delta27) protects against cerebral malaria caused by Plasmodium falciparum; however, it is unknown whether this polymorphism also protects against
Malaria knowledge and long-lasting insecticidal net use in rural communities of central Côte d'Ivoire (Publications)
BACKGROUND: To improve effectiveness of malaria control interventions, it is essential to deepen the knowledge of contextual factors that govern people's practice for preventive and curative measures. [...] N'Dakonankro and Yoho) located in central Cote d'Ivoire. Indicators of socioeconomic position (SEP), malaria knowledge and practice, placing special emphasis on LLINs, were investigated during a cross-sectional [...] were used, as appropriate. RESULTS: Significant differences were found...
Ensemble modeling of the likely public health impact of a pre-erythrocytic malaria vaccine (Publications)
BACKGROUND: The RTS,S malaria vaccine may soon be licensed. Models of impact of such vaccines have mainly considered deployment via the World Health Organization's Expanded Programme on Immunization (EPI)
<em>Anopheles plumbeus</em> (Diptera: Culicidae) in Europe: a mere nuisance mosquito or potential malaria vector? (Publications)
of humans between Europe and malaria endemic countries and changes in environment and climate, these data strongly suggest that An. plumbeus could act as a vector for malaria and thus significantly contribute [...] to increasing the malaria transmission risk in Central-Western Europe. In locations showing high vulnerability to the presence of gametocyte carriers, the risk of transmission of malaria by An. plumbeus [...] ABSTRACT: BACKGROUND: Anopheles plumbeus has been recognized as a minor...
Simulation of the cost-effectiveness of malaria vaccines (Publications)
vaccination over 50% often exceed the benefits. CONCLUSION: The simulations indicate malaria vaccines might be efficient malaria control interventions, and that both transmission setting and vaccine delivery [...] BACKGROUND: A wide range of possible malaria vaccines is being considered and there is a need to identify which vaccines should be prioritized for clinical development. An important element of the information [...] individual-based stochastic model for the natural history and...
Quantifying behavioural interactions between humans and mosquitoes: Evaluating the protective efficacy of insecticidal nets against malaria... (Publications)
ABSTRACT: BACKGROUND: African malaria vectors bite predominantly indoors at night so sleeping under an Insecticide-Treated Net (ITN) can greatly reduce malaria risk. Behavioural adaptation by mosquitoes [...] allow vector mosquitoes to bite outside of peak sleeping hours and undermine efficacy of this key malaria prevention measure. METHODS: High coverage with largely untreated nets has been achieved in the Kilombero [...] peak sleeping hours, respectively. ITNs consistently conferred > 70%...
Spatio-temporal analysis of the role of climate in inter-annual variation of malaria incidence in Zimbabwe (Publications)
inter-annual variation in malaria incidence. Quantitative description of the space-time effect of this association has practical implications for the development of operational malaria early warning system [...] system (MEWS) and malaria control. We used Bayesian negative binomial models for spatio-temporal analysis of the relationship between annual malaria incidence and selected climatic covariates at a district level [...] 1988-1999. RESULTS: Considerable inter-annual variations were observed...
Target product profile choices for intra-domiciliary malaria vector control pesticide products: repel or kill? (Publications)
BACKGROUND: The most common pesticide products for controlling malaria-transmitting mosquitoes combine two distinct modes of action: 1) conventional insecticidal activity which kills mosquitoes exposed [...] mosquitoes to non-users rather than killing them outright. METHODS: A process-explicit model of malaria transmission is described which captures the sequential interaction between deterrent and toxic actions
Spatio-temporal malaria transmission patterns in Navrongo demographic surveillance site, northern Ghana (Publications)
BACKGROUND: The relationship between entomological measures of malaria transmission intensity and mortality remains uncertain. This is partly because transmission is heterogeneous even within small ge [...] analysed data from Kassena-Nankana districts in northern Ghana to obtain small area estimates of malaria transmission rates allowing for this uncertainty.METHODS: Independent Bayesian geostatistical models [...] mosquito densities.CONCLUSION: This study confirms the presence of...
From strategy development to routine implementation: the cost of Intermittent Preventive Treatment in Infants for malaria control (Publications)
