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...
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...

resistance to disease interventions. We address two important pathogens: malaria and SARS-Cov-2. As we get closer to eliminating malaria and other diseases, preventing diseases from evolving resistance to response [...] detailed parasite models, mosquito-to-human transmission models and adapt individual-level models for malaria. We will also adapt models of SARS-CoV-2 to examine the emergence of vaccine-resistant COVID variants [...] pathogens. We will examine resistance to vaccines, drugs and...
Dietary diversity in primary schoolchildren of south-central Côte d'Ivoire and risk factors for non-communicable diseases (Publications)
prediabetes and malaria infection, as well as medium and high DDS. Overweight was associated with malaria infection and moderate anaemia. CONCLUSION: Overweight, prediabetes, low HDL-C, malaria, and anaemia [...] the primary caretaker according to the guideline of Food and Agriculture Organization. Anaemia, malaria, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and blood [...] health in Taabo. Our findings highlight interactions between infectious...
Effects of pyrethroid resistance on the cost effectiveness of a mass distribution of long-lasting insecticidal nets: a modelling study (Publications)
were used. The epidemiological models, implemented in OpenMalaria, were employed to study the impact of a single mass distribution of LLINs on malaria, both in terms of episodes prevented during the effective [...] BACKGROUND: The effectiveness of insecticide-treated nets in preventing malaria is threatened by developing resistance against pyrethroids. Little is known about how strongly this affects the effectiveness [...] levels of mortality in World Health Organization susceptibility tests,...
Do holes in long-lasting insecticidal nets compromise their efficacy against pyrethroid resistant <em>Anopheles gambiae</em> and <em>Culex... (Publications)
BACKGROUND: Resistance of malaria vectors to pyrethroids threatens the effectiveness of long-lasting insecticidal nets (LLINs) as a tool for malaria control. Recent experimental hut and observational studies [...] round holes. This study examines whether there is a threshold above which LLINs no longer reduce malaria transmission. METHODS: Intact and artificially-holed LLINs under three months old and untreated nets [...] evaluated in terms of protection against blood feeding, insecticidal...
