Abstract

As our world becomes increasingly interconnected, threats to global public health continue to proliferate. New and novel risks to health have emerged consistently over the past 30 years. Moreover, our shrinking world now allows health threats to spread more quickly than ever before. Given these realities, efforts to protect and improve global health must be expansive, flexible, and able to take into account the variety of circumstances that may imperil good health. These efforts also must consider the multiple levels and varying contexts in which laws, policies, and other factors govern global health and affect health outcomes.
