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...
Haematological consequences of acute uncomplicated <em>falciparum </em>malaria: a WorldWide Antimalarial Resistance Network pooled analysis of... (Publications)
falciparum malaria to identify the factors associated with malarial anaemia. METHODS: Individual patient data from eligible antimalarial efficacy studies of uncomplicated P. falciparum malaria, available [...] BACKGROUND: Plasmodium falciparum malaria is associated with anaemia-related morbidity, attributable to host, parasite and drug factors. We quantified the haematological response following treatment of [...] = 2.06 [95%CI 1.39-3.05], p < 0.001). CONCLUSIONS: In patients with uncomplicated...
Insights from modelling malaria vaccines for policy decisions: the focus on RTS,S (Publications)
ns. This review illustrates the utility of simulation approaches by reviewing the literature on malaria vaccine modelling, with a focus on its link to the development of policy guidance for the first licensed
Methods and indicators for measuring patterns of human exposure to malaria vectors (Publications)
BACKGROUND: Effective targeting and evaluation of interventions that protect against adult malaria vectors requires an understanding of how gaps in personal protection arise. An improved understanding [...] collected and used consistently, this information can contribute to an improved understanding of how malaria transmission persists in the context of current intervention tools, how exposure patterns may change
Malaria infection prevalence and sensitivity of reactive case detection in Zanzibar (Publications)
BACKGROUND: Reactive case detection (RCD) is a commonly used strategy for malaria surveillance and response in elimination settings. Many approaches to RCD assume detectable infections are clustered within [...] household and up to 9 additional neighboring households. RESULTS: Of 12,487 participants tested by malaria rapid diagnostic test (RDT), 3.2% of those residing in index households and 0.4% of those residing [...] Sensitivity of RDT to detect qPCR-detectable infections was 34% (95%CI:...
