Bioterrorism is terrorism by intentional release or dissemination of biological agents (bacteria, viruses or toxins); these may be in a naturally-occurring or in a human-modified form.

[edit] Definition

According to the U.S. Centers for Disease Control and Prevention (CDC) 1:

A bioterrorism attack is the deliberate release of viruses, bacteria, or other germs (agents) used to cause illness or death in people, animals, or plants. These agents are typically found in nature, but it is possible that they could be changed to increase their ability to cause disease, make them resistant to current medicines, or to increase their ability to be spread into the environment. Biological agents can be spread through the air, through water, or in food. Terrorists may use biological agents because they can be extremely difficult to detect and do not cause illness for several hours to several days. Some bioterrorism agents, like the smallpox virus, can be spread from person to person and some, like anthrax, can not.

[edit] History

Biological terrorism dates as far back as ancient Roman civilization, where dead and rotting animals were thrown into wells to poison water supplies (Bock, 2001.) This early version of biological terrorism was used to destroy enemy forces covertly. It continued on into the 14th century where the bubonic plague was used to infiltrate enemy cities by both instilling the fear of infection in residences, in hopes that they would evacuate, and also to destroy defending forces that would not yield to the attack. The use of disease as a weapon in this stage of history exhibited a lack of control aggressors had over their own biological weapon. Primitive medical technology provided limited means of protection for the aggressor and a battles surrounding geographical regions. After the battle was won, the inability to contain enemies who escaped death lead to wide spread epidemics affecting not only the enemy forces, but also surrounding regions inhabitants. Due to the use of these biological weapons, and the apparent lack of medical advancement necessary to defend surrounding regions from them, wide spread epidemics such as the bubonic plague quickly moved across all of Western Europe, destroying a large portion of its population. The victims of biological terrorism in fact became weapons themselves. This was noted in the Middle Ages, but medical advancements had not progressed far enough to prevent the consequences of a weapons use (Eitzen and Takafuji, 1997).

In the 15th century, smallpox was used on contaminated clothing to defeat South American and Native American forces (Bock, 2001). Again, the use of biological weapons for which limited protection and containment was available, lead to casualties on both sides of battles. Bioterrorism continued to be an effective method of weakening an adversary but it was also difficult to contain. In the Revolutionary War, colonists were vaccinated from the small-pox virus and then used the virus to intentionally infect enemies. This demonstrates a major advancement in the evolution of bioterrorism. Once the ability to defend from biological warfare became possible through medical advancement, the weapons became far more valuable.

As time continued the use of biological warfare became more and more sophisticated. Countries were developing weapons that delivered much higher effectiveness and less chance of infecting the wrong party. One significant enhancement in biological weapon development was the first use of Anthrax. Anthrax effectiveness was initially limited to victims of large dosages. This became a weapon of choice because it is easily transferred, has a high mortality rate, and can be easily obtained. Also, variants of the Anthrax bacterium can be found all around the world making it the biological weapon of choice in the early 19th century. Another property of Anthrax that helped fuel its use as a biological weapon is its poor ability to spread far beyond the targeted population.

By the time World War I began, attempts to use anthrax were directed at animal populations. This was ineffective. Instead, the use of poisonous mustard gas became the biological weapon of choice. The sheer horror of its affects lead to a treaty called the Geneva Protocol of 1925. The treaty was created to prevent the use of asphyxiating gas as a method of biological warfare (Brooks, 2001). While this was a significant advancement toward the prevention of biological weapon use, the treaty said nothing about weapon development. Secretly, biological weapon development programs existed in many nations. While no documented instances of biological weapon use exist it is believed that this was primarily due to the programs immaturity and not the unwillingness to use them.

American biological weapon development began in 1942. President Franklin D. Roosevelt placed George W. Merck in charge of the effort to create a development program. You may recognize the name Merck, Mr. Merck is also the founder of Merck Pharmaceuticals. These programs continued until 1969, when by executive order President Richard Nixon shut down all programs related to American offensive use of biological weapons (http://fas.org/nuke/guide/usa/cbw/bw.html).

Accusations of the use of biological weapons against North Korea were spread during Viet Nam, however it is believed that those accusations were propaganda developed by the North Korean regime to villainize American Armed Forces. As the 70’s passed, global efforts to prevent the development of biological weapons and their use were widespread. In 1972 the prohibition of development, production and stockpiling biological weapons was developed.

In the 1980’s Iraq made substantial efforts to develop and stockpile large amounts of biological weapons. By the end of the 80’s Iraq had several sites dedicated to the research and development of biological warfare. They began to test their findings in the late 80’s. These actions lead to the first Gulf war in which Iraq’s biological weapons were dismantled and destroyed.

Since that time, efforts to use biological warfare has been more apparent in small radical organizations attempting to create fear in the eyes of large groups. Some efforts have been partially effective in creating fear, due to the lack of visibility associated with modern biological weapon use by small organizations. In 1995 a small terrorist group launched a terrorist attack aboard a Tokyo subway. The attack killed twelve and affected more than 5000. The response of Japanese emergency services successfully prevented an outcome with much higher mortality rates.

In the United States a more recent biological terrorism attack occurred in 2001 when letters laced with infectious anthrax were delivered to news media offices and the U.S Congress (Johnston, 2005). The letters killed five individuals.
