“Public health legal preparedness” is a term born in the ferment, beginning in the late 1990s, that has led to unprecedented recognition of the essential role law plays in public health and, even more recently, in protecting the public from terrorism and other potentially catastrophic health threats.The initial articulation of public health has not kept pace with rapid evolution in the concept and in practical development of public health preparedness itself. This poses the risk that legal preparedness may fall behind (...) construction of general readiness in the public health system—and may, in fact, undercut achievement of comprehensive public health preparedness for massive threats to health in both the United States and world-wide. Inadvertent results might include both negative health impacts and infringement on individual rights. (shrink)
