The Eco-epidemiology Research Group is comprised of four research units performing basic and applied research at the interface between pathogen, vector, host and environment: Entomology (UE), Veterinary Helminthology (UH), Medical Helminthology and Eco-modelling (EM). In a global context, many infectious diseases continue to (re)emerge with unexpected distributions and unprecedented intensities, while other endemic diseases persist. Recognising that pathogen-, vector-, animal- and human host populations interact with each other and with the environment, we apply a whole system approach (One Health, Eco-health) to understand the transmission and to improve the prevention, control and/or elimination of infectious diseases. We do this by interdisciplinary research, combining field epidemiology and ecology with lab-based research and modelling. Our focus is on neglected tropical diseases (NTDs) and malaria, with specific emphasis on vector-borne diseases, zoonoses, and parasite (co-)infections.
