Potential Bioterrorism Agents
CDC Category A Agents
Highest priority agents. Organisms that pose a risk to national security because they can be easily disseminated or transmitted from person to person; that result in high mortality rates and have the potential for major public health impact; that might cause public panic and social disruption; and that require special action for public health preparedness.
CDC Category B Agents
Second highest priority agents. Organisms that are moderately easy to disseminate; that result in moderate morbidity rates and low mortality rates; and that require enhanced diagnostic capacity and disease surveillance.
