This book outlines a systems approach for public health, discussing the need for a population-based framework for practice, research, policy, and community engagement. It is useful for policymakers, practitioners, business and community leaders, and educators alike in evaluating the status of public health infrastructure
Public Health Authority
The authority to act to protect and promote the public's health has emerged over the course of our Nation’s history, and has enabled many of modern public health’s greatest achievements. Today, public health agencies use their authority to promote health, prevent the spread of infectious disease, protect against environmental hazards, advance equity and assure local public health infrastructure and health services. During declared emergencies, state and federal authorities have broader powers to act to assist governments, suspend or modify legal requirements, pass and enforce law and expend funds for the health, safety and welfare of society. Recently, some states have moved to limit public health powers. Such efforts pose a mounting challenge for public health’s response to COVID-19 and future threats.
