Traditional public health is rapidly transforming itself from state programs to prevent disease in populations (e.g., vaccinations and newborn screening) to federal and international efforts to more broadly promote the "right to health." This problem-oriented seminar enables students to answer questions about health risks as such questions typically arise in practice. It covers contemporary examples of the seven deadly sins -- anger, gluttony, lust, sloth -- plus drugs, alcohol, tobacco, firearms, biobanks, epidemics, bioweapons, and surveillance. The seminar offers a systematic framework for identifying and controlling health risks, drawing on theories of risk perception, cognitive reasoning, and empirical evidence. Students analyze and compare the applicability and effectiveness of different legal strategies to control risks, such as criminal and civil prohibitions, mandatory product standards, tort liability, mandatory data collection, biometric testing, conditions of employment, marketing restrictions, quarantine, and taxation. Emphasis is on the different scope of laws (state, federal and international) regulating personal behavior and laws regulating products and commercial activities. A writing project to develop a legal strategy to address a contemporary risk to health is required.
