Designed as a supplemental text for introductory courses in public health practice at the undergraduate and graduate levels, Contemporary Public Health provides historical background that contextualizes the current state of the field and explores the major issues practitioners face today. It addresses essential topics such as the social and ecological determinants of health and their impact on practice, marginalized populations, the role of community-oriented primary care, accreditation, and the organizational landscape of the American public health system. Finally, it examines the opioid epidemic, the impact of pandemics including COVID-19, and international public health and explores the potential of systems based on multilevel partnerships of government, academic, and nonprofit organizations.
