The mission of public health has been succinctly stated as “the fulfillment of society’s interest in assuring conditions in which people can be healthy” (1). Public and private institutions charged with this mission monitor population health and respond when threats arise. These may be sudden health crises (eg, infectious outbreaks), persistent health problems (eg, chronic diseases), or buildups of environmental risk factors (eg, pollution). Public health practitioners use a combination of disciplines that include basic science, clinical research, epidemiology, statistics, behavioral research, health care services, economics, and policy to identify the primary or secondary causes of health threats and then systematically prevent, mitigate, or suppress these causes in entire populations. This approach has been tremendously successful against infectious diseases and has had notable successes against injuries, accidents, and major chronic diseases (2,3). The purpose of this essay is to highlight the case of a group of nearly 7,000 rare (low-prevalence) diseases, mostly of genetic or congenital origin, for which the applicability of the public health approach, primary prevention in particular, seems limited. We argue that a wider application of this approach could greatly benefit the patients affected by these diseases and their relatives. We start by presenting the challenges of implementing this approach for rare diseases, then we present the need for such an approach and a few notable examples of its successful application to these diseases. Finally, we provide a structured list of public health activities that are key to the management of rare diseases in populations.
