National Intelligence Estimate: Global Infectious Disease Threat and Its Implications for the United States [open pdf - 2MB]
"This [National Intelligence Estimate] report represents an important initiative on the part of the Intelligence Community to consider the national security dimension of a nontraditional threat. It responds to a growing concern by senior US leaders about the implications-in terms of health, economics, and national security-of the growing global infectious disease threat. The dramatic increase in drugresistant microbes, combined with the lag in development of new antibiotics, the rise of megacities with severe health care deficiencies, environmental degradation, and the growing ease and frequency of cross-border movements of people and produce have greatly facilitated the spread of infectious diseases."
