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...
<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...
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%...
Preventing childhood malaria in Africa by protecting adults from mosquitoes with insecticide-treated nets (Publications)
BACKGROUND: Malaria prevention in Africa merits particular attention as the world strives toward a better life for the poorest. Insecticide-treated nets (ITNs) represent a practical means to prevent malaria in [...] targets for ITN coverage beyond vulnerable groups. METHODS AND FINDINGS: Using field-parameterized malaria transmission models, we show that high (80% use) but exclusively targeted coverage of young children
A virosomal malaria peptide vaccine elicits a long-lasting sporozoite-inhibitory antibody response in a phase 1a clinical trial (Publications)
CSP-specific antibodies elicited in this phase 1a trial. METHODOLOGY/PRINCIPAL FINDINGS: 46 healthy malaria-naive adults were immunized with virosomal formulations of two peptide-phosphatidylethanolamine
From strategy development to routine implementation: the cost of Intermittent Preventive Treatment in Infants for malaria control (Publications)
Saharan Africa. Intermittent Preventive Treatment in infants (IPTi) is a promising new tool for malaria control. Although efficacy information is available for many interventions, there is a dearth of
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...
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...
Modelling the epidemiological impact of intermittent preventive treatment against malaria in infants (Publications)
preventive treatment against malaria in infants (IPTi) using sulphadoxine-pyrimethamine (SP) have shown a positive, albeit variable, protective efficacy against clinical malaria episodes. The impact of IPTi [...] periods. The predicted cumulative benefits were proportionately slightly greater for severe malaria episodes and malaria-attributable mortality than for acute episodes in the settings modelled. Modest increased [...] mortality. METHODS/PRINCIPAL FINDINGS: We used a comprehensive,...
