Biological weapons

[GarryDrold]

Biological warfare is the use of microbiological agents as weapons. Such use is contrary to international law and has rarely taken place during formal warfare in modern history, despite the extensive preparations and stockpiling of biological agents carried out during the 20th century.
(See also Overview of Incidents Involving Mass-Casualty Weapons.)
Biological weapons are thought by some to be ideal weapons for terrorists. These agents may be delivered in secret and have delayed effects, allowing the perpetrator to remain undetected.
The US Centers for Disease Control and Prevention (CDC) has created a priority list of biological agents and toxins (see table CDC High-Priority Biological Agents and Toxins). The highest priority are Category A.
The deliberate use of biological weapons to cause mass casualties would probably entail the use of aerosols. Inhalational anthrax and pneumonic plague are the two diseases most likely to occur under these circumstances.
