Time to move from presumptive malaria treatment to laboratory-confirmed diagnosis and treatment in African children with fever (Publications)
declining malarial transmission in parts of sub-Saharan Africa, declining proportions of fevers due to malaria, and the availability of rapid diagnostic tests mean it may be time for this policy to change. This [...] to support a shift toward laboratory-confirmed rather than presumptive diagnosis and treatment of malaria in children under five
Simulated impact of RTS,S/AS01 vaccination programs in the context of changing malaria transmission (Publications)
INTRODUCTION: The RTS,S/AS01 pre-erythrocytic malaria vaccine is in phase III clinical trials. It is critical to anticipate where and how it should be implemented if trials are successful. Such planning [...] planning may be complicated by changing levels of malaria transmission. METHODS/RESULTS: Computer simulations were used to examine RTS,S/AS01 impact, using a vaccine profile based on phase II trial results,
Temporal correlation between malaria and rainfall in Sri Lanka (Publications)
potential use for malaria prediction. However, the relationship between rainfall and the number of malaria cases is indirect and complex. METHODS: The statistical relationships between monthly malaria case count
Age-patterns of malaria vary with severity, transmission intensity and seasonality in sub-Saharan Africa: a systematic review and pooled analysis (Publications)
P. falciparum clinical malaria, hospital admissions with malaria and malaria-diagnosed mortality. Studies were allocated to a 3x2 matrix of intensity and seasonality of malaria transmission. Maximum likelihood [...] falciparum malaria were concentrated in the youngest age groups across all settings. Despite recently observed declines in malaria transmission in several countries, which will shift the burden of malaria cases [...] for each outcome. Clinical malaria incidence was relatively evenly...
Virosome-formulated <em>Plasmodium falciparum</em> AMA-1 & CSP derived peptides as malaria vaccine: randomized phase 1b trial in semi-immune... (Publications)
evaluate the safety and immunogenicity of two virosome formulated malaria peptidomimetics derived from Plasmodium falciparum AMA-1 and CSP in malaria semi-immune adults and children. METHODS: The design was a [...] age-deescalating study with two immunizations. 10 adults and 40 children (aged 5-9 years) living in a malaria endemic area were immunized with PEV3B or virosomal influenza vaccine Inflexal(R)V on day 0 and 90 [...] from 4 to 66 in children. As an exploratory outcome, we found that the...
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
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,...
Epidemiology and clinical features of vivax malaria imported to Europe: sentinel surveillance data from TropNetEurop (Publications)
Plasmodium vivax is the second most common species among malaria patients diagnosed in Europe, but epidemiological and clinical data on imported P. vivax malaria are limited. The TropNetEurop surveillance network [...] network has monitored the importation of vivax malaria into Europe since 1999. OBJECTIVES: To present epidemiological and clinical data on imported P. vivax malaria collected at European level. MATERIAL AND [...] AND METHODS: Data of primary cases of P. vivax malaria reported...
Mapping malaria risk among children in Côte d'Ivoire using Bayesian geo-statistical models (Publications)
estimated 767,000 disability-adjusted life years are due to malaria, placing the country at position number 14 with regard to the global burden of malaria. Risk maps are important to guide control interventions [...] ons, and hence, the aim of this study was to predict the geographical distribution of malaria infection risk in children aged
Potential benefits, limitations and target product-profiles of odor-baited mosquito traps for malaria control in Africa (Publications)
as suitable technologies for controlling malaria and other mosquito-borne diseases. We investigated the potential benefits of such traps for preventing malaria transmission in Africa and the essential [...] users and non-users of insecticide-treated nets (ITNs), currently the primary malaria prevention method. We determined that malaria transmission declines as trap coverage (proportion of total availability of [...] match the impact of 50% community-wide ITN coverage. If such traps are used to...
