One Health: much more than a slogan.

So, what is ‘One Health’? How does this concept help us think through, and perhaps solve, public health problems? One Health places disease, particularly infection, in a broad ecological context. Many agents of infection target hosts beyond humans, and One Health seeks to understand and explain the public health implications of broad host ranges. OneHealth is a modern restatement of the old epidemiological triad of host, agent and environment.
