NORTHEASTERN LAW — Constitutional law has helped make Americans unhealthy, argues public health law expert Professor Wendy E. Parmet in her new book, Constitutional Contagion: COVID, the Courts, and Public Health. Drawing from law, history, political theory and public health research, Constitutional Contagion explores the history of public health laws, the nature of liberty and individual rights, and the forces that make a nation more or less vulnerable to contagion.
