About This Course

One Health: People, Animals & Ecosystems is the catalogue's most comprehensive health course, built around the insight that human, animal and environmental health are one system. Ten modules span the foundations of One Health, ecosystems and biodiversity, zoonotic disease emergence and spillover, antimicrobial resistance, food systems and health security, climate as a disease driver, surveillance and outbreak investigation, governance and multisectoral coordination, community engagement and risk communication, and emerging tools — with a capstone in which you design a feasible One Health intervention.
