The "One Health"€ approach has evolved from earlier concepts which were associated with the contributions made by veterinarians to public health. It is based on recognising the influence of the complex interactions and inter-dependencies between animals, humans and the environment, embedded within a recognition of the fundamental importance of a healthy and balanced global ecosystem and its biodiversity for the wellbeing of humans, and other animals. The course will introduce the students to these complex relationships, and encourage personal reflection with respect to their role as citizens and as veterinarians in this context. Through a combination of lectures, tutorials and field trips involving appropriate practitioners of One Health from Hong Kong, it will deepen the students' exposure to and appreciation of the subject matter. This course establishes an intellectual framework which will be carried through and touched upon throughout the curriculum.
