12 - Bioterrorism

Abstract

Bioterrorism is defined as the deliberate and malicious deployment of microbial agents or their toxins as weapons in a non-combat setting, represents perhaps the most overt example of human behavior impacting epidemic infectious diseases. There is historical precedent for the use of biological agents against both military and civilian populations. The use of biological (and chemical) agents as weapons of war has been well documented. The German biological warfare program during World War I included covert infections of Allied livestock with anthrax and glanders. The Japanese army began conducting experiments on the effects of bacterial agents of biowarfare on Chinese prisoners in occupied Manchuria in 1932 at their infamous Unit 731. The United States began its own offensive biological weapons program in 1942 and, during its 28-year official existence, weaponized and stockpiled lethal biological agents, such as anthrax, as well as incapacitating agents, such as the etiologic agent of Q fever. There are some recent examples of bioterrorism, though not necessarily resulting in attacks causing morbidity or mortality, may serve as harbingers of future events. Saddam Hussein's regime in Iraq developed and deployed anthrax and botulinum-laden warheads in the years leading up to the Gulf War. The reasons that these weapons were never used in an actual attack probably had more to do with the implicit threat of overwhelming US retaliation and Iraqi technological deficiencies rather than the regime's reluctance to violate any moral principles. Biological agents have also been used to forward political ideologies: in 1984 a religious cult, intent on influencing voter turnout during a local election, contaminated restaurant salad bars in The Dalles, Oregon.
