Characterising co-infections with <em>Plasmodium </em>spp., <em>Mansonella perstans</em> or <em>Loa loa </em>in asymptomatic children, adults and... (Publications)
Equatorial Guinea are lacking. We aimed to demonstrate that blood retained on malaria rapid diagnostic tests, commonly deployed for malaria surveys, could be used as a source of nucleic acids for molecular based [...] with malaria in an asymptomatic population. METHODOLOGY: M. perstans, L. loa and Plasmodium spp. parasites were monitored by qPCR in a cross-sectional study using DNA extracted from a subset malaria rapid [...] rapid diagnostic tests (mRDTs) collected during the annual malaria...
Analysis of nucleic acids extracted from rapid diagnostic tests reveals a significant proportion of false positive test results associated with recent... (Publications)
Surveillance programmes often use malaria rapid diagnostic tests (RDTs) to determine the proportion of the population carrying parasites in their peripheral blood to assess the malaria transmission intensity. Despite [...] quality control activities for RDTs deployed in malaria surveillance programmes. Methods: The diagnostic performance of field-deployed RDTs used for malaria surveys was assessed by retrospective molecular [...] P. falciparum histidine rich protein 2 (PfHRP2) antigen...
Transcriptional correlates of malaria in RTS,S/AS01-vaccinated African children: a matched case-control study (Publications)
ted BTM correlations with malaria risk appeared to generalize to healthy, malaria-naive adults. CONCLUSIONS: A prevaccination transcriptomic signature associates with malaria in RTS,S/AS01-vaccinated African [...] we assessed the generalizability of our findings across three controlled human malaria infection studies of healthy, malaria-naive adult RTS,S/AS01 recipients. RESULTS: RTS,S/AS01 vaccination was associated [...] month 3 levels correlated with malaria risk. In contrast, baseline levels...
Infectivity of symptomatic malaria patients to <em>Anopheles farauti</em> colony mosquitoes in Papua New Guinea (Publications)
to mosquitoes is an understudied bottleneck in the transmission of malaria. Direct membrane feeding assays (DMFA) allow detailed malaria transmission studies from humans to mosquitoes. Especially for Plasmodium [...] were performed with venous blood collected from rapid diagnostic test (RDT) positive symptomatic malaria patients and subsequently analysed by light microscopy and quantitative real time polymerase chain
Sub-national tailoring of malaria interventions in mainland Tanzania: simulation of the impact of strata-specific intervention combinations using... (Publications)
2015-2020 national malaria strategic plan (NMSP) and the epidemiological risk stratification at the council level in 2018. METHODS: Intervention mixes, selected by the National Malaria Control Programme [...] either based on estimates from the malaria indicator survey in 2016 or set to a hypothetical target of 85%. A previously calibrated mathematical model in OpenMalaria was used to compare intervention impact [...] BACKGROUND: To accelerate progress against malaria in high burden countries, a...
Evaluating malaria prevalence and land cover across varying transmission intensity in Tanzania using a cross-sectional survey of school-aged children (Publications)
n of malaria in sub-Saharan Africa has become increasingly stratified following decades of malaria control interventions. The extent to which environmental and land cover risk factors for malaria may differ [...] and could provide actionable targets to maximize the success of malaria control efforts. METHODS: This study used cross-sectional malaria survey data from a nationally representative cohort of school-aged [...] land cover and malaria prevalence within three distinct strata of...
Tenfold difference in DNA recovery rate: systematic comparison of whole blood vs. dried blood spot sample collection for malaria molecular... (Publications)
BACKGROUND: Molecular and genomic surveillance is becoming increasingly used to track malaria control and elimination efforts. Blood samples can be collected as whole blood and stored at - 20 degrees C
