The global dimensions of public health preparedness and implications for US action.

The globalization of public health is both real and relevant throughout the United States and to Americans traveling or residing abroad. US public policy responses are evolving, but a crisper and more comprehensive global perspective is needed. I suggest four timely US actions to address today's competing realities of globalization and economic austerity: raise awareness among clinicians and local health departments; capture and share exemplary disaster management practices across countries; ensure that US global health investments are effective, efficient, and sustainable; and think globally while acting locally to enhance US health security. The reauthorization of the Pandemic and All-Hazards Preparedness Act of 2006 provides an opportunity to more clearly address the global dimensions of domestic preparedness.
