High-priority agents include organisms that pose a risk to national security because they can be easily disseminated or transmitted from person to person, cause high mortality and have the potential for major public health impact, might cause public panic and social disruption, and require special action for public health preparedness.

Category B Diseases/Agents

Second highest priority agents include those that are moderately easy to disseminate, cause moderate morbidity and low mortality, and require specific enhancements of CDC's diagnostic capacity and enhanced disease surveillance.

Category C Diseases/Agents

Third highest priority agents include emerging pathogens that could be engineered for mass dissemination in the future because of availability, ease of production and dissemination, and potential for high morbidity and mortality and major health impact.
