"It is a vital interest of the United States to manage the risk of biological incidents. In today's interconnected world, biological incidents have the potential to cost thousands of American lives, cause significant anxiety, and greatly impact travel and trade. [...] Biological threats--whether naturally occurring, accidental, or deliberate in origin--are among the most serious threats facing the United States and the international community. [...] Health security means taking care of the American people in the face of biological threats to our homeland and to our interests abroad. [...] The health of the American people depends on our ability to stem infectious disease outbreaks at their source, wherever and however they occur. America's biodefense enterprise needs to be nimble enough to address emerging infectious disease threats, the risks associated with the accelerating pace of biotechnology, and threats posed by terrorist groups or adversaries seeking to use biological weapons. [...] This National Biodefense Strategy highlights the President's commitment to protect the American people and our way of life, laying out a clear pathway and set of objectives to effectively counter threats from naturally occurring, accidental, and deliberate biological events. It is broader than a Federal Government strategy. It is a call to action for state, local, territorial, and tribal (SLTT) entities, other governments, practitioners, physicians, scientists, educators, and industry."
