Categories of Biological Agents

The federal government has defined the pathogens or toxins that have the potential to pose a severe threat to public health or safety.

The Centers for Disease Control (CDC) categorized these critical agents into three groups:

  • Category A agents (highest priority)
  • Category B agents (second highest priority)
  • Category C agents (third highest priority)

The biological agents are placed in one of the three groups depending on the level of risk each poses to national security.
