Bioterrorism Category A high priority agents are described as which of the following?

• A. Bioterrorism Category A high priority agents are described as organisms that can be easily disseminated or transmitted from person to person, cause high mortality, and require special public health preparedness
• B. Bioterrorism Category A high priority agents are non-biological threats
• C. Bioterrorism Category A high priority agents are defined purely by their economic impact
• D. Bioterrorism Category A high priority agents are not a priority for public health

Answer: (A)

Category A high-priority bioterrorism agents are defined by their potential to cause mass casualties and require urgent public health measures because they can be spread easily and result in high mortality. The best choice describes agents that can be disseminated or transmitted from person to person, cause significant death, and demand special public health preparedness to detect, respond, and contain. This captures the core traits that make these agents the top priority for surveillance and readiness, such as smallpox, anthrax, plague, botulinum toxin, tularemia, and certain viral hemorrhagic fevers. The other options miss the key point: these agents are biological threats, not non-biological, they are not defined purely by economic impact, and they are indeed a priority for public health.
