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
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 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...
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
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...
Allomonal effect of breath contributes to differential attractiveness of humans to the African malaria vector Anopheles gambiae (Publications)
contributes to between-person differences in relative attractiveness to the highly anthropophilic malaria vector Anopheles gambiae sensu stricto remains unknown and was the focus of the present study. METHODS: [...] contributor to between-person differences in the relative attractiveness of humans to this important malaria vector
Interpreting malaria age-prevalence and incidence curves: a simulation study of the effects of different types of heterogeneity (Publications)
Individuals in a malaria endemic community differ from one another. Many of these differences, such as heterogeneities in transmission or treatment-seeking behaviour, affect malaria epidemiology. The [...] heterogeneity were incorporated into a comprehensive individual-based model of Plasmodium falciparum malaria epidemiology. The different types of heterogeneity were systematically simulated individually, and
Determinants of the cost-effectiveness of intermittent preventive treatment for malaria in infants and children (Publications)

METHODS: We use a dynamic, individual-based simulation model of Plasmodium falciparum malaria epidemiology, antimalarial drug [...] preventive treatment in infants (IPTi) and children (IPTc) have shown promising results in reducing malaria episodes but with varying efficacy and cost-effectiveness. The effects of different intervention [...] g and more expensive drugs, high frequencies of drug resistance and high levels...
The acceptability of intermittent preventive treatment of malaria in infants (IPTi) delivered through the expanded programme of immunization in... (Publications)
BACKGROUND: Intermittent preventive treatment of malaria in infants (IPTi) reduces the incidence of clinical malaria. However, before making decisions about implementation, it is essential to ensure that [...] attitudes or adherence to the expanded programme on immunisation (EPI) or treatment seeking or existing malaria prevention. CONCLUSION: In order to improve adherence to both EPI and IPTi local priorities should
