Differential impact of malaria control interventions on <em>P. falciparum</em> and <em>P. vivax</em> infections in young Papua New Guinean children (Publications)
children and the key risk factors for malaria infection and illness in 2013. RESULTS: Between 2006 and 2008, P. falciparum infection prevalence, molFOB, and clinical malaria episodes reduced by 47%, 59% and [...] INTRODUCTION: As malaria transmission declines, understanding the differential impact of intensified control on Plasmodium falciparum relative to Plasmodium vivax and identifying key drivers of ongoing [...] cohort, children aged 1-5 years were actively monitored for infection and...
Investigating the drivers of the spatio-temporal patterns of genetic differences between <em>Plasmodium falciparum</em> malaria infections in Kilifi... (Publications)
Knowledge of how malaria infections spread locally is important both for the design of targeted interventions aiming to interrupt malaria transmission and the design of trials to assess the interventions [...] to account for the observed patterns. The mean geographic distance between parent and offspring malaria infections for the base model was 0.5 km (95% CI 0.3-1.5), for a distribution with 68% of distances
Strengthening surveillance systems for malaria elimination by integrating molecular and genomic data (Publications)
elimination efforts are currently going on with the objective of reducing malaria morbidity and mortality by 90% and malaria elimination in at least 35 countries by 2030. Strengthening surveillance systems [...] Unprecedented efforts in malaria control over the last 15 years have led to a substantial decrease in both morbidity and mortality in most endemic settings. However, these progresses have stalled over [...] such as polymerase chain reaction (PCR) and quantitative PCR (qPCR) are...
The development and evaluation of a self-marking unit to estimate malaria vector survival and dispersal distance (Publications)
diseases such as malaria. Mosquito mark-release-recapture (MMRR) experiments are a popular method of measuring the survival and dispersal of disease vectors; however, examples with African malaria vectors are [...] This study demonstrates the successful use of a self-marking device in an MMRR study with African malaria vectors. This method may be useful in investigating population structure and dispersal of mosquitoes
<em>Vivax </em>malaria in pregnancy and lactation: a long way to health equity (Publications)
BACKGROUND: The Sustainable Development Goals (SDG) call for increased gender equity and reduction in malaria-related mortality and morbidity. Plasmodium vivax infections in pregnancy are associated with maternal [...] is hindered by gender-specific complexities. CASE PRESENTATION: A symptomatic episode of vivax malaria at 18 weeks of gestation in a primigravid woman was associated with maternal anaemia, a recurrent [...] treatment and found to be heterozygous for Mahidol variant. CONCLUSION:...
Malaria elimination transmission and costing in the Asia-Pacific: developing an investment case (Publications)
the regional goal of malaria elimination by 2030 will require an intensification of efforts and a plan for sustainable financing. This article presents an investment case for malaria elimination to facilitate [...] billion. Malaria elimination provides a 6:1 return on investment. Conclusion: This investment case provides compelling evidence for the benefits of continued prioritization of funding for malaria and can [...] Background: The Asia-Pacific region has made significant progress against m...
Molecular malaria surveillance using a novel protocol for extraction and analysis of nucleic acids retained on used rapid diagnostic tests (Publications)
Acids from RDTs) approach; a complete workflow for large-scale molecular malaria surveillance. Using RDTs collected during a malaria indicator survey we demonstrated that ENAR provides a powerful tool to [...] The use of malaria rapid diagnostic tests (RDTs) as a source for nucleic acids that can be analyzed via nucleic acid amplification techniques has several advantages, including minimal amounts of blood [...] systematically developed and extensively evaluated a procedure to extract total...
The duration of chemoprophylaxis against malaria after treatment with artesunate-amodiaquine and artemether-lumefantrine and the effects of <em>pfmdr1... (Publications)
BACKGROUND: The majority of Plasmodium falciparum malaria cases in Africa are treated with the artemisinin combination therapies artemether-lumefantrine (AL) and artesunate-amodiaquine (AS-AQ), with a [...] amodiaquine being also widely used as part of seasonal malaria chemoprevention programs combined with sulfadoxine-pyrimethamine. While artemisinin derivatives have a short half-life, lumefantrine and a [...] reinfection. The estimated duration of chemoprophylaxis was then used in a...
