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
Determinants of the cost-effectiveness of intermittent preventive treatment for malaria in infants and children (Publications)
seasonality, proportions of malaria fevers treated and drug characteristics. 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...
Safety of falciparum malaria diagnostic strategy based on rapid diagnostic tests in returning travellers and migrants: a retrospective study (Publications)
developed severe malaria while 6/137 of both RDT and BS positive did so. The use of RDT allowed a reduction of a median of 2.1 hours to get a first malaria test result.CONCLUSIONS: A malaria diagnostic strategy [...] tests for malaria (RDT) allow accurate diagnosis and prompt treatment. Validation of their usefulness in travellers with fever was needed. The safety of a strategy to diagnose falciparum malaria based on [...] those, 2/2028 (0.1%) developed uncomplicated malaria with both RDT and BS...
Experience and challenges from clinical trials with malaria vaccines in Africa (Publications)
clinical trials and malaria control programmes as part of the Global Malaria Action Plan (GMAP). GMAP outlined and support global strategies toward the elimination and eradication of malaria in many areas, [...] Malaria vaccines are considered amongst the most important modalities for potential elimination of malaria disease and transmission. Research and development in this field has been an area of intense effort [...] Despite this, there is currently no licensed malaria vaccine. Researchers,...
<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...
Cost-effectiveness of intermittent preventive treatment of malaria in infants (IPTi) for averting anaemia in Gabon: a comparison between intention to... (Publications)
BACKGROUND: In Gabon, the impact of intermittent preventive treatment of malaria in infants (IPTi) was not statistically significant on malaria reduction, but the impact on moderate anaemia was, with some differences
A review of malaria vaccine clinical projects based on the WHO rainbow table (Publications)
As the malaria community considers the potential role of a first-generation malaria vaccine in malaria control efforts, it is an apposite time to carefully document terminated and ongoing malaria vaccine [...] Phase 3 testing of the most advanced malaria vaccine, RTS,S/AS01, indicates that malaria vaccine R&D is moving into a new phase. Field trials of several research malaria vaccines have also confirmed that [...] applied to increase the chances of success for second-generation malaria...
Simulation of malaria epidemiology and control in the highlands of western Kenya (Publications)
METHODS: Individual-based stochastic simulation models of malaria in humans and a deterministic model of malaria in mosquitoes as part of the OpenMalaria platform were parameterized to create a scenario for [...] to assist in planning for the control and elimination of malaria. This work investigates the applicability of mathematical modelling of malaria transmission dynamics in Rachuonyo South, a district with [...] CONCLUSIONS: The OpenMalaria model of P. falciparum transmission can be used to...
Population hemoglobin mean and anemia prevalence in Papua New Guinea: new metrics for defining malaria endemicity? (Publications)
