Micro-encapsulated pirimiphos-methyl shows high insecticidal efficacy and long residual activity against pyrethroid-resistant malaria vectors in... (Publications)
e-treated nets and indoor residual spraying (IRS) has contributed to a considerable decrease of malaria morbidity and mortality in sub-Saharan Africa over the last decade. Due to increasing resistance [...] for IRS with long-lasting residual activity are required to sustain the gains obtained in most malaria-endemic countries. METHODS: Three experimental capsule suspension (CS) formulations of the organ [...] alternatives for IRS, as they demonstrate prolonged insecticidal effect and residual...

Therefore, the current trial was designed to measure and compare prevention of malaria infection by mosquito coils or long-lasting in [...] members that regularly slept away from home. The main outcome of interest was Plasmodium falciparum malaria prevalence detected by rapid diagnostic tests (RDTs) during six repeated monthly cross-sectional [...] This is the first robust clinical evaluation of transfluthrin mosquito coils as a...

Seasonally dependent relationships between Indicators of malaria transmission and disease provided by mathematical model simulations (Publications)
levels of malaria transmission, patterns of seasonality and access to treatment were run with an ensemble of models of malaria epidemiology and within-host dynamics, as part of the OpenMalaria modeling [...] relationships between malaria indicators allowing more easily measured data, such as routine health systems data on case incidence, to be translated into measures of transmission and other malaria indicators. [...] previously published data on these same indicators as observed in malaria...
Made-to-measure malaria vector control strategies: rational design based on insecticide properties and coverage of blood resources for mosquitoes (Publications)
Eliminating malaria from highly endemic settings will require unprecedented levels of vector control. To suppress mosquito populations, vector control products targeting their blood hosts must attain high
Increasing role of <em>Anopheles funestus</em> and <em>Anopheles arabiensis</em> in malaria transmission in the Kilombero Valley, Tanzania (Publications)
order to sustain the gains achieved by current malaria control strategies, robust surveillance systems that monitor dynamics of vectors and their roles in malaria transmission over time are essential. This [...] This longitudinal study demonstrates the trends in malaria vector dynamics and their relative contribution to malaria transmission in hyperendemic transmission settings in Tanzania. METHODS: The study was [...] arabiensis susceptibility to insecticides was assessed using WHO guidelines....

The paper explored the contribution of malaria relative [...] remained the leading cause of death for neonates, malaria remains as the leading cause of death for post-neonates followed by pneumonia. However, declines in malaria death rates accounted for 49.9% of the observed [...] accounted for only 19.9%. CONCLUSION: To achieve MDG 4 in mal...
