Community-based surveillance to monitor mortality in a malaria-endemic and Ebola-epidemic setting in rural Guinea (Publications)
a reinforced malaria control program and one sous-prefecture without (Koundou) in Guinea. Deaths were recorded by key informants and classified as due to malaria or another cause. Malaria deaths were those [...] deaths were reported from July 2011-June 2014, of which 55.2% (N = 686) were reported as due to malaria. Malaria-attributable proportional mortality decreased by 26.5% (95% confidence interval [CI] = 13.9-33 [...] those reported as due to malaria or fever in the 3 days before death with...
Sensitive and accurate quantification of human malaria parasites using droplet digital PCR (ddPCR) (Publications)
of parasite density in the human host is essential for understanding the biology and pathology of malaria. Semi-quantitative molecular methods are widely applied, but the need for an external standard curve
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...
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...

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
Susceptibility of <em>Anopheles gambiae</em> to insecticides used for malaria vector control in Rwanda (Publications)
a major threat to the gains made in malaria control. To monitor the presence and possible emergence of resistance against a variety of insecticides used for malaria control in Rwanda, nationwide insecticide [...] using the synergist PBO. CONCLUSION: This is the first nationwide study of insecticide resistance in malaria vectors in Rwanda. It shows the gradual increase of insecticide resistance to pyrethroids (lambd [...] testing and implement an insecticide resistance management strategy to...
Nouvelles approches pour la prévention de la malaria chez le voyageur (Publications)
Malaria is declining in many tropical countries. This reduction challenges our usual preventive strategies. In moderate to low risk areas, the Swiss guidelines recommend a stand-by emergency treatment [...] making through three clinical studies. The first showed that travelers visiting moderate to low risk malaria areas prefer a standby emergency treatment rather than chemoprophylaxis. The second study investigates
