What is bioterrorism?

Bioterrorism is a form of terrorism where there is the intentional release of biological agents (bacteria, viruses, or other germs). This is also referred to as germ warfare. Terrorism is defined by the United States government as the "unlawful use of force and violence against persons or property to intimidate or coerce a government, the civilian population, or any segment thereof, in furtherance of political or social objectives." In addition to biological agents, terrorists can also utilize chemical agents and nuclear bombs. While a biological agent may injure or kill people, animals, or plants, the goal for the terrorist is to further their social and political goals. Many biological agents are found in nature; however, they can be modified by the terrorist to make them more dangerous. Some of these agents can be transmitted from person to person, and the infection may take hours or days to become apparent.

What are the biological agents that can be utilized for bioterrorism?

While any germ, bacteria, or virus could potentially be utilized by terrorist, there are a number of biological agents that have been recognized as being more likely to be utilized. The reason for these agents being of concern is based on their availability to terrorists and the ease by which these agents can be disseminated. The U.S. Centers for Disease Control and Prevention (CDC) has developed a classification system for biological terror agents, which is available on their web site (Categories). The classification is based on the likelihood of the agent being used and the risk posed by each agent. The agents (and the diseases they cause) are listed in table 1, including hyperlinks for those wishing to learn more about a specific agent or disease. However, it is almost impossible for most people to memorize all the details about each of these agents. It is more important for the general public to understand the risk of bioterrorism and the appropriate response to a terrorist attack.
