Highly heterogeneous residual malaria risk in western Thailand (Publications)
substantial and poses a challenge for the national malaria elimination program. To determine epidemiological parameters as well as risk factors for malaria infection in western Thailand, we carried out a [...] Over the past decades, the malaria burden in Thailand has substantially declined. Most infections now originate from the national border regions. In these areas, the prevalence of asymptomatic infections [...] provinces on the Thailand-Myanmar border. Blood samples from 999 local...
High cure rates and tolerability of artesunate-amodiaquine and dihydroartemisinin-piperaquine for the treatment of uncomplicated falciparum malaria in... (Publications)
BACKGROUND: The Tanzanian National Malaria Control Programme (NMCP) and its partners have been implementing regular therapeutic efficacy studies (TES) to monitor the performance of different drugs used [...] mefantrine, which is the first-line anti-malarial for the treatment of uncomplicated falciparum malaria. Data on the performance of other artemisinin-based combinations is urgently needed to support timely [...] parasitological responses of ASAQ and DP for directly observed treatment of...
Insufficient sensitivity of laser desorption-time of flight mass spectrometry-based detection of hemozoin for malaria screening (Publications)
detection of hemozoin was assessed for its performance characteristics as a rapid screening test for malaria. In spite of good specificity of > 95%, poor sensitivity of 80.2% for microscopically positive samples
RTS,S malaria vaccine pilot studies: addressing the human realities in large-scale clinical trials (Publications)
A malaria vaccine as part of the integrated malaria control and elimination efforts will have a major impact on public health in sub-Sahara Africa. The first malaria vaccine, RTS,S, now enters pilot i [...] the malaria vaccine clinical trial experiences, key ethical practices for effective clinical trial research in low-resource settings are described. For successful vaccine integration into malaria intervention
Linking human behaviours and malaria vector biting risk in south-eastern Tanzania (Publications)
To accelerate malaria elimination in areas where core interventions such as insecticide-treated nets (ITNs) are already widely used, it is crucial to consider additional factors associated with persistent [...] persistent transmission. Qualitative data on human behaviours and perceptions regarding malaria risk was triangulated with quantitative data on Anopheles mosquito bites occurring indoors and outdoors in sou [...] south-eastern Tanzania communities where ITNS are already used but lower...
Spatial-temporal heterogeneity in malaria receptivity is best estimated by vector biting rates in areas nearing elimination (Publications)
when vector control can be withdrawn after malaria is eliminated depend on the receptivity or potential of an area to support vector populations. To guide malaria control and elimination programmes, the potential [...] estimate malaria receptivity and transmission were compared within and among geographically localised villages of active transmission in the Western Province of the Solomon Islands. RESULTS: Malaria transmission [...] inoculation and parity rates could not be measured with the...
Diagnostic performance of conventional and ultrasensitive rapid diagnostic tests for malaria in febrile outpatients in Tanzania (Publications)
Background: A novel ultra-sensitive malaria RDT (us-RDT) has been developed for improved active P.falciparum case detection. The utility of this us-RDT in clinical diagnosis and fever management has not [...] infections. Conclusion: There is neither gain nor risk to apply us-RDT rather than co-RDT for clinical malaria diagnosis. In febrile patients, only a small proportion of infections are characterized by parasite
Inter-sectoral approaches for the prevention and control of malaria among the mobile and migrant populations: a scoping review (Publications)
knowledge about malaria, initiation and promotion of bed nets utilization, increased access to diagnosis and treatment in a surveillance context and contributed towards a reduction in malaria transmission [...] with correct knowledge about malaria transmission (70%, 95% CI 57-83%). Interventions targeting the use of bed nets utilization were two times more likely to reduce malaria incidence amongst the targeted [...] BACKGROUND: Malaria cases among mobile and migrant populations (MMPs) represent...
Adherence to intermittent preventive treatment for malaria in Papua New Guinean infants: a pharmacological study alongside the randomized controlled... (Publications)
(IPTi) trial that took place in Papua New Guinea showed an overall reduction of 29% of the risk of malaria when delivering single-dose sulfadoxine-pyrimethamine (SP) associated to 3 days of amodiaquine (AQ) [...] to discuss the efficacy of the intervention and on feasibility of self-administered preventive malaria treatment. METHODS AND FINDINGS: During the three-arm randomized double-blinded IPTi trial, each [...] studied when discussing the efficacy of the interventions in trials...
