Naturally acquired immune responses to <em>P. vivax</em> merozoite surface protein 3alpha and merozoite surface protein 9 are associated with reduced... (Publications)
is the most geographically widespread human malaria parasite. Cohort studies in Papua New Guinea have identified a rapid onset of immunity against vivax-malaria in children living in highly endemic areas [...] and Merozoite Surface Protein 9 (PvMSP9) were measured and related to prospective risk of P. vivax malaria during 16 months of active follow-up. Overall, there was a low prevalence of antibodies to PvMSP3alpha [...] PvMSP9 N-terminus (aIRR = 0.68, p = 0.035) were associated with protection...
Seeking treatment for symptomatic malaria in Papua New Guinea (Publications)
reported suffering from malaria in the previous four weeks. A probit model was then used to identify the factors determining whether or not people sought treatment for presumptive malaria. Multinomial logit [...] BACKGROUND: Malaria places a significant burden on the limited resources of many low income countries. Knowing more about why and where people seek treatment will enable policy makers to better allocate [...] resources. This study aims to better understand what influences...
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,...
Inaugural meeting of the malaria policy advisory committee to the WHO: conclusions and recommendations (Publications)
conclusions and recommendations from that meeting, as part of the newly launched Malaria Journal thematic series "WHO Malaria Policy Advisory Committee: Reports and Recommendations".Summaries are provided [...] sessions on global malaria control, drug resistance and containment, rapid diagnostic test procurement criteria, larviciding, classification of countries for elimination, estimating malaria cases and deaths [...] The Malaria Policy Advisory Committee to the World Health Organization met...
