Bioterrorism agents are classified by threat level into three categories (A, B, and C) based on their potential to cause death or disease through weaponization; Category A represents high-priority select agents with features such as ease of dissemination and high lethality, while Categories B and C represent intermediate and lower-risk agents respectively. The core theoretical framework defines these biological threats—encompassing bacteria, viruses, toxins, and rickettsiae—by their specific virulence mechanisms (e.g., toxin production, cell entry systems) and transmission vectors that facilitate mass casualty events or warfare applications. This classification system serves as a standardized public health domain within microbiology to prioritize resource allocation for surveillance, treatment algorithms, and countermeasure development against intentional biological attacks.
