Bioterrorism-Related

Bioterrorism agents are divided into three categories based on their ease of spread and the severity of illness they cause. Category A agents are most dangerous, and Category C agents are current emerging threats.

 

Category A

Category A pathogens are those organisms/biological agents that pose the highest risk to national security and public health because they

• Can be easily spread or transmitted from person to person
• Result in high death rates and have the potential for major public health impact
• Might cause public panic and social disruption
• Require special action for public health preparedness.

 

Category B

Category B pathogens are the second highest priority organisms/biological agents. They

• Are moderately easy to disseminate
• Result in moderate morbidity rates and low mortality rates
• Require specific enhancements for diagnostic capacity and enhanced disease surveillance.

 

Category C

Category C pathogens are the third highest priority and include emerging pathogens that could be engineered for mass dissemination in the future because of

• Availability
• Ease of production and dissemination
• Potential for high morbidity and mortality rates and major health impact.
