Essentials of Public Health, Second Edition, published in partnership with the American Public Health Association, serves as a foundational text for students preparing for a career in the burgeoning sector of public health. Drawn from his extensive experience in the Illinois public health system, author Bernard J. (Barney) Turnock, MD, MPH, combines the best elements of his other two books, Public Health: What It Is and How It Works and Public Health: Career Choices That Make a Difference, for this addition to the Essential Public Health Series. Dr. Turnock's accessible style and comprehensive exploration of the field offers students unique exposure to both the internal workings of public health organizations as well as the various roles and responsibilities of the professionals who drive their operations. Ideally suited for students on a professional public health track seeking to increase their understanding of the organization and activities of health departments, the text also surveys the variety of public health careers including administration, environmental and occupational health, nursing, epidemiology, and disease control. Essentials of Public Health, Second Edition offers a strong introduction to promoting population health with clear, reader-friendly language and learning tools, while exploring practical applications of a public health career and addressing issues such as the size and scope of the workforce, salary expectations, and job security. --Book Jacket.
