The epidemiological triad: Interaction of host, environment, and pathogen determine disease and pathogen ecology. Some factors influencing the components of the triad are shown for the current epidemiological triad (top panel). Potential changes in the epidemiological triad are shown in the bottom panels through a changing climate and a resulting change in the environmental component of the triad.
