The landmark 1988 Institute of Medicine report The Future of Public Health served the public health community well by pointing to what needed to be done, fostering a sense of urgency, and offering concrete directions to be pursued. In this article, the impact of the 1988 report, and of the subsequent 2003 report on the Centers for Disease Control and Prevention (CDC), is considered by tracing the course of the ideas that influenced the consciousness of the public health community and subsequently catalyzed concrete action. Among these ideas was that "public health is in disarray." This assessment led to an awareness that something needed to be done. Further, by stating that the public health enterprise had 3 core functions (assessment, policy development, and assurance), the 1988 report set in motion policy development to address the "disarray." At a more fundamental level, both reports championed the need for governmental public health (particularly at the CDC) to take action to strengthen the capacity of local and state public health agencies to address a growing range of public health threats and emergencies.
