Application of Wastewater-based Epidemiology to SARS-CoV-2 Detection
We combine computational, experimental and clinical approaches to develop a clearer view of microbiomes.
Inhalation of legionella bacteria – which thrive in warm water – can cause illness: in a new project, an Eawag-led multidisciplinary research team is investigating how the risks associated with these bacteria can best be managed.
