The definition of epidemiology ends with the following phrase: “…and the application of this study to the control of health problems.” While some academically minded epidemiologists have stated that epidemiologists should stick to research and not get involved in policy development or even make
recommendations, public health epidemiologists do not have this luxury. Indeed, epidemiologists who understand a problem and the population in which it occurs are often in a uniquely qualified position to recommend appropriate interventions. As a result, epidemiologists working in public health regularly provide input, testimony, and recommendations regarding disease control strategies, reportable disease regulations, and healthcare policy.
