Modelling the impact of adopting new-generation insecticide-treated nets on malaria transmission and insecticide resistance

Abstract Background The widespread insecticide resistance increasingly threatens malaria elimination, prompting a reassessment of vector control strategies. As Tanzania transitions from standard pyrethroid-only insecticide-treated nets (ITNs) to new-generation nets, evaluating th...

Aquatic predators as complementary tools for mosquito vector control: current evidence, ecological considerations, and future directions

Insecticide-based strategies for mosquito control are increasingly constrained by insecticide resistance, sparking interest in eco-friendly alternatives, one of which is the use of aquatic predators to reduce mosquito densities. Evidence from laboratory, semi-field, and localized...

Occupational radiation exposure among healthcare workers in fluoroscopy-guided interventional procedures: A multi-centre longitudinal study in Tanzania

Fluoroscopy-guided interventional procedures (FGIPs) are increasingly used in modern medicine because they offer minimally invasive diagnostic and therapeutic options, but they also expose healthcare workers to ionizing radiation. In Tanzania, occupational dose data for staff inv...

Metagenomic Profiling of Diarrheagenic Escherichia coli Pathotypes Reveals Predominance of Diffusely Adherent and Enteroaggregative Subtypes and Mixed Signatures Among Under-Fives in Tanzania

Diarrheagenic Escherichia coli (DEC) is a leading enteric pathogen in children under five in sub-Saharan Africa, yet conventional targeted assays fail to capture mixed virulence signatures or provide quantitative context relative to E. coli carriage. We applied a virulence-aware...

Spatiotemporal patterns of ambient NO2 and NO pollution in Kigali Rwanda

Abstract Kigali, like many cities in sub-Saharan Africa, faces rapid urban growth alongside the need to manage air pollution and protect public health. Despite its policy efforts, systematic data on nitrogen oxides (NO x : NO 2 and NO), key indicators of combustion-related pollut...
