enzymes in the sensitivity of the malaria parasites to pantothenamides. These pantothenamide compounds with a new mode of action may have potential as drugs against malaria parasites. [...] Malaria eradication is critically dependent on new therapeutics that target resistant Plasmodium parasites and block transmission of the disease. Here, we report that pantothenamide bioisosteres were active

transmission and whether they need to be detected and targeted to achieve malaria elimination. In this study we analyse a range of malaria datasets to quantify the density, detectability, course of infection [...] Malaria infections occurring below the limit of detection of standard diagnostics are common in all endemic settings. However, key questions remain surrounding their contribution to sustaining transmission

Health information given by Swiss travel agencies (Publications)
agents mentioned preventive measures against malaria, but only 69% indicated the need for vaccinations against other diseases. Spontaneous advice on malaria risk and vaccinations was better than advice [...] through travel agencies every year. These agencies are thus an important source of information about malaria and other important health risks and little is known about the appropriate health information provided [...] advice given upon prompting.

Indigenous emergence and spread of <em>kelch13</em> C469Y artemisinin-resistant <em>Plasmodium falciparum</em> in Uganda (Publications)
As part of the Community Access to Rectal Artesunate for Malaria project, we collected blood samples from 697 children with signs of severe malaria in northern Uganda between 2018 and 2020, before and after [...] Artemisinin-based combination therapies (ACTs) were introduced as the standard of care for uncomplicated malaria in Africa almost two decades ago. Recent studies in East Africa have reported a gradual increase [...] geographic origin of k13 mutations. Of the 697 children, 540 were...
Following in Soper's footsteps: northeast Brazil 63 years after eradication of <em>Anopheles gambiae</em> (Publications)
years ago was a new and horrifying experience. This African mosquito is an exceptionally effective malaria vector because it is well adapted to feeding upon people and to exploiting aquatic habitats associated [...] with our daily activities. Anopheles gambiae sensu lato probably accounts for most of the world's malaria deaths and socioeconomic burden. Fortunately, the Brazilian experience had a happy ending. The prospect [...] aegypti elimination, the Rockefeller Foundation and Brazilian...
Spatially-explicit risk profiling of<em> Plasmodium falciparum</em> infections at a small scale: a geostatistical modelling approach (Publications)
BACKGROUND: There is a renewed political will and financial support to eradicate malaria. Spatially-explicit risk profiling will play an important role in this endeavour. Patterns of Plasmodium falciparum [...] falciparum infection prevalence were examined among schoolchildren in a highly malaria-endemic area. METHODS: A questionnaire was administered and finger prick blood samples collected from 3,962 children, aged [...] the questionnaire on children's socioeconomic status and the use of bed...
