Biodefense is defined as those actions designed to counter biological threats, reduce risks, and prepare for, respond to, and recover from bioincidents, whether naturally occurring, accidental, or deliberate in origin and whether impacting human, animal, plant, or environmental health.
Biodefense incorporates a wide range of activities, including biosurveillance, threat monitoring and awareness, biological arms control and nonproliferation, counterterrorism, biosafety and biosecurity, the development of medical countermeasures, medical planning and preparedness, and response and recovery activities. The
National Biodefense Strategy and Implementation Plan for Countering Biological Threats, Enhancing Pandemic Preparedness, and Achieving Global Health Security (the National Biodefense Strategy) provides a framework for coordinating these diverse activities across federal departments and agencies.
