Bioterrorism

Image
Bioterrorism is terrorism involving the intentional release or dissemination of biological agents. These agents are bacteria, viruses, insects, fungi, or toxins, and may be in a naturally occurring or a human-modified form, in much the same way in biological warfare. Further, modern agribusiness is vulnerable to anti-agricultural attacks by terrorists, and such attacks can seriously damage economy as well as consumer confidence. The later destructive activity is called agrobioterrorism and is subtype of agro-terrorism.

Definition

Bioterrorism is the deliberate release of viruses, bacteria, toxins or other harmful agents to cause illness or death in people, animals, or plants. These agents are typically found in nature, but could be mutated or altered 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, water, or in food. Biological agents are attractive to terrorists because they are 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, cannot. Bioterrorism may be favored because biological agents are relatively easy and inexpensive to obtain, can be easily disseminated, and can cause widespread fear and panic beyond the actual physical damage. Military leaders, however, have learned that, as a military asset, bioterrorism ...

History

By the time World War I began, attempts to use anthrax were directed at animal populations. This generally proved to be ineffective. Shortly after the start of World War I, Germany launched a biological sabotage campaign in the United States, Russia, Romania, and France. At that time, Anton Dilger lived in Germany, but in 1915 he was sent to the United States carrying cultures of glanders, a virulent disease of horses and mules. Dilger set up a laboratory in his home in Chevy Chase, Maryland. He used stevedores working the docks in Baltimore to infect horses with glanders while they were waiting to be shipped to Britain. Dilger was under suspicion as being a German agent, but was never arrested. Dilger eventually fled to Madrid, Spain, where he died during the Influenza Pandemic of 1918. In 1916, the Russians arrested a German agent with similar intentions. Germany and its allies infected French cavalry horses and many of Russia's mules and horses on the Eastern Front. These action...

Scenarios

There are multiple considerable scenarios, how terrorists might employ biological agents. In 2000, tests conducted by various US agencies showed that indoor attacks in densely populated spaces are much more serious than outdoor attacks. Such enclosed spaces are large buildings, trains, indoor arenas, theaters, malls, tunnels and similar. Contra-measures against such scenarios are building architecture and ventilation systems engineering. In 1993, sewage was spilled out into a river, subsequently drawn into the water system and affected 400,000 people in Milwaukee, Wisconsin. The disease-causing organism was cryptosporidium parvum. This man-made disaster can be a template for a terrorist scenario. Nevertheless, terrorist scenarios are considered more likely near the points of delivery than at the water sources before the water treatment. Release of biological agents is more likely for a single building or a neighborhood. Contra-measures against this scenario is the further limitation of...

The examples and perspective in this section deal primarily with the United States and do not represent a worldwide view of the subject . You may improve this section, discuss the issue on the talk page, or create a new section, as appropriate. ( June 2012 ) (Learn how and when to remove this template message) Under current United States law, bio-agents which have been declared by the U.S. Department of Health and Human Services or the U.S. Department of Agriculture to have the "potential to pose a severe threat to public health and safety" are officially defined as "select agents." The CDC categorizes these agents (A, B or C) and administers the Select Agent Program, which regulates the laboratories which may possess, use, or transfer select agents within the United States. As with US attempts to categorize harmful recreational drugs, designer viruses are not yet categorized and avian H5N1 has been shown to achieve high mortality and human-communication in a lab...

Planning and response

You may improve this section, discuss the issue on the talk page, or create a new section, as appropriate. ( June 2012 ) (Learn how and when to remove this template message) Planning may involve the development of biological identification systems. Until recently in the United States, most biological defense strategies have been geared to protecting soldiers on the battlefield rather than ordinary people in cities. Financial cutbacks have limited the tracking of disease outbreaks. Some outbreaks, such as food poisoning due to E. coli or Salmonella , could be of either natural or deliberate origin. Preparedness edit Export controls on biological agents are not applied uniformly providing terrorists a route for acquisition. Laboratories are working on advanced detection systems to provide early warning, identify contaminated areas and populations a...

Response to bioterrorism incident or threat

The examples and perspective in this section deal primarily with the United States and do not represent a worldwide view of the subject . You may improve this section, discuss the issue on the talk page, or create a new section, as appropriate. ( June 2012 ) (Learn how and when to remove this template message) Government agencies which would be called on to respond to a bioterrorism incident would include law enforcement, hazardous materials and decontamination units, and emergency medical units, if available. The US military has specialized units, which can respond to a bioterrorism event; among them are the United States Marine Corps' Chemical Biological Incident Response Force and the U.S. Army's 20th Support Command (CBRNE), which can detect, identify, and neutralize threats, and decontaminate victims exposed to bioterror agents. US response would include the Centers for Disease Control. Historically, governments and authorities have relied on quarantines to protect thei...
