Hemolysis after oral artemisinin combination therapy for uncomplicated <em>Plasmodium falciparum</em> malaria (Publications)
weeks after treatment of severe malaria with intravenous artesunate have been described. We performed a prospective observational study of patients with uncomplicated malaria to investigate whether posttreatment [...] occurs after oral artemisinin-based combination therapy. Eight of 20 patients with uncomplicated malaria who were given oral artemisinin-based combination therapy met the definition of posttreatment hemolysis [...] g/dL; p = 0.002). These findings indicate a need for increased...
Mass mosquito trapping for malaria control in western Kenya: study protocol for a stepped wedge cluster-randomised trial (Publications)
of malaria threaten the efficacy of existing vector control tools used against malaria mosquitoes. The development of odour-baited mosquito traps has led to the possibility of controlling malaria through [...] mass mosquito trapping could be an effective tool for elimination of malaria. If proven to be effective, this novel approach to malaria control would be a valuable addition to the existing strategies of [...] through mass trapping of malaria vectors. Through daily removal trapping against...
Evaluation of malaria diagnoses using a handheld light microscope in a community-based setting in rural Côte d'Ivoire (Publications)
Portable microscopy may facilitate quality diagnostic care in resource-constrained settings. We compared a handheld light microscope (Newton Nm1) with a mobile phone attachment to conventional light m
Pregnant women and infants as sentinel populations to monitor prevalence of malaria: results of pilot study in Lake Zone of Tanzania (Publications)
screened for malaria infection using a malaria rapid diagnostic test (RDT) from December 2012 to November 2013, regardless of symptoms. Participants who tested positive were treated for malaria per national [...] BACKGROUND: As malaria control interventions are scaled-up, rational approaches are needed for monitoring impact over time. One proposed approach includes monitoring the prevalence of malaria infection among [...] facility (HF) visits. This pilot explored the feasibility and utility of...
Mapping intra-urban malaria risk using high resolution satellite imagery: a case study of Dar es Salaam (Publications)
of malaria in rapidly growing African urban settlements. The complex and heterogeneous nature of urban malaria requires a better understanding of the spatial and temporal patterns of urban malaria risk [...] localized heterogeneity of malaria transmission and develop a high resolution predictive malaria risk map of Dar es Salaam. RESULTS: Results indicate that the risk of malaria infection varied across the [...] settlements by 2030, the burden of malaria among urban populations in Africa...
Spatially aggregated clusters and scattered smaller loci of elevated malaria vector density and human infection prevalence in urban Dar es Salaam,... (Publications)
density and eight of malaria infection prevalence were detected over both phases. Only a third of vectors were collected in hotspots in phase 1 (30 %) and phase 2 (33 %). Malaria prevalence hotspots accounted [...] BACKGROUND: Malaria transmission, primarily mediated by Anopheles gambiae, persists in Dar es Salaam (DSM) despite high coverage with bed nets, mosquito-proofed housing and larviciding. New or improved [...] improved vector control strategies are required to eliminate malaria from...
Mapping hotspots of malaria transmission from pre-existing hydrology, geology and geomorphology data in the pre-elimination context of Zanzibar,... (Publications)
BackgroundLarval source management strategies can play an important role in malaria elimination programmes, especially for tackling outdoor biting species and for eliminating parasite and vector populations [...] larval source management requires tools for identifying geographic foci of vector proliferation and malaria transmission where these efforts may be concentrated. Previous studies have relied on surface topographic [...] examine the relationship between dry and wet season spatial...
Estimating malaria burden in Nigeria: a geostatistical modelling approach (Publications)
This study has produced a map of malaria prevalence in Nigeria based on available data from the Mapping Malaria Risk in Africa (MARA) database, including all malaria prevalence surveys in Nigeria that [...] correlating with malaria presence were land surface temperature for day and rainfall. It was also found that malaria prevalence increased with distance to water bodies up to 4 km. The malaria risk map estimated [...] low malaria prevalence were found to be scattered around the country with...
Severe malaria in Europe: an 8-year multi-centre observational study (Publications)
lly confirmed severe Plasmodium falciparum malaria according to the 2006 WHO criteria. RESULTS: From 2006 to 2014 a total of 185 patients with severe malaria treated in 12 European countries were included [...] patients with severe malaria in this study were tourists or migrants acquiring the infection in West Africa. Intravenous artesunate is increasingly used for treatment of severe malaria in many European treatment [...] BACKGROUND: Malaria remains one of the most serious infections for...
