Beyond informatics: an electronic community infrastructure for public health

Public health agencies are in the early stages of building an electronic infrastructure that will link them to each other and eventually to the "information superhighway." Emphasis in planning and development is on data systems and the information and training services that can enhance essential public health services. This article argues for a larger vision of the potential of electronic networks for public health. It discusses the health and other challenges facing public health, the limitations of conventional efforts, and the emerging consensus on public health core functions. Finally, it examines current and potential uses of information technology. The article concludes by proposing that the public health community should develop a collaborative and inclusive vision of public health in an electronic world and provide guidance and support for agency implementation to ensure a stronger system that can meet the health and health equity challenges ahead.
