Medical defense against biological warfare or terrorism is an area of study unfamiliar to most military and civilian health care providers during peacetime. In the aftermath of Operations Desert Shield/Desert Storm, it became obvious that the threat of biological attacks against our soldiers was real. Increased incidents and threats of domestic terrorism (e.g., New York City World Trade Center bombing, Tokyo subway sarin release, Oklahoma City federal building bombing, Atlanta Centennial Park bombing) as well as numerous anthrax hoaxes around the country have brought the issue home to civilians as well. Other issues, including the disclosure of a sophisticated offensive biological warfare program in the Former Soviet Union (FSU), have reinforced the need for increased training and education of health care professionals on how to prevent and treat biological warfare casualties.
Numerous measures to improve preparedness for and response to biological warfare or terrorism are ongoing at local, state, and federal levels. Training efforts have increased both in the military and civilian sectors. The Medical Management of Chemical and Biological Casualties Course taught at both USAMRIID and USAMRICD trains over 560 military medical professionals each year on both biological and chemical medical defense. The highly successful 3-day USAMRIID satellite course on the Medical Management of Biological Casualties has reached over 40,000 medical personnel over the last three years.
Through this handbook and the training courses noted above, medical professionals will learn that effective medical countermeasures are available against many of the bacteria, viruses, and toxins, which might be, used as biological weapons against our military forces or civilian communities. The importance of this education cannot be overemphasized and it is hoped that our physicians, nurses, and allied medical professionals will develop a solid understanding of the biological threats we face and the medical armamentarium useful in defending against these threats.
The global biological warfare threat is serious, and the potential for devastating casualties is high for certain biological agents. There are at least 10 countries around the world currently that have offensive biological weapons programs. However, with appropriate use of medical countermeasures either already developed or under development, many casualties can be prevented or minimized.
The purpose for this handbook is to serve as a concise pocket-sized manual that will guide medical personnel in the prophylaxis and management of biological casualties. It is designed as a quick reference and overview, and is not intended as a definitive text on the medical management of biological casualties.
HISTORY OF BIOLOGICAL WARFARE
AND CURRENT THREAT
The use of biological weapons in warfare has been recorded throughout history. Two of the earliest reported uses occurred in the 6th century BC, with the Assyrians poisoning enemy wells with rye ergot, and Solon's use of the purgative herb hellebore during the siege of Krissa. In 1346, plague broke out in the Tartar army during its siege of Kaffa (at present day Feodosia in Crimea). The attackers hurled the corpses of plague victims over the city walls; the plague epidemic that followed forced the defenders to surrender, and some infected people who left Kaffa may have started the Black Death pandemic, which spread throughout Europe. Russian troops may have used the same tactic against Sweden in 1710.
On several occasions, smallpox was used as a biological weapon. Pizarro is said to have presented South American natives with variola-contaminated clothing in the 15th century, and the English did the same when Sir Jeffery Amherst provided Indians loyal to the French with smallpox-laden blankets during the French and Indian War of 1754 to 1767. Native Americans defending Fort Carillon sustained epidemic casualties which directly contributed to the loss of the fort to the English.
In this century, there is evidence that during World War I, German agents inoculated horses and cattle with glanders in the U.S. before the animals were shipped to France. In 1937, Japan started an ambitious biological warfare program, located 40 miles south of Harbin, Manchuria, in a laboratory complex code-named "Unit 731". Studies directed by Japanese General Ishii continued there until 1945, when the complex was burned. A post World War II investigation revealed that the Japanese researched numerous organisms and used prisoners of war as research subjects. Slightly less than 1,000 human autopsies apparently were carried out at Unit 731, mostly on victims exposed to aerosolized anthrax. Many more prisoners and Chinese nationals may have died in this facility - some have estimated up to 3,000 human deaths. Following reported overflights by Japanese planes suspected of dropping plague-infected fleas, a plague epidemic ensued in China and Manchuria. By 1945, the Japanese program had stockpiled 400 kilograms of anthrax to be used in a specially designed fragmentation bomb.
In 1943, the United States began research into the use of biological agents for offensive purposes. This work was started, interestingly enough, in response to a perceived German biological warfare (BW) threat as opposed to a Japanese one. The United States conducted this research at Camp Detrick (now Fort Detrick), which was a small National Guard airfield prior to that time, and produced agents at other sites until 1969, when President Nixon stopped all offensive biological and toxin weapon research and production by executive order. Between May 1971 and May 1972, all stockpiles of biological agents and munitions from the now defunct U.S. program were destroyed in the presence of monitors representing the United States Department of Agriculture, the Department of Health, Education, and Welfare, and the states of Arkansas, Colorado, and Maryland. Included among the destroyed agents were Bacillus anthracis, botulinum toxin, Francisella tularensis, Coxiella burnetii, Venezuelan equine encephalitis virus, Brucella suis, and Staphylococcal enterotoxin B. The United States began a medical defensive program in 1953 that continues today at USAMRIID.
In 1972, the United States, UK, and USSR signed the Convention on the Prohibition of the Development, Production and Stockpiling of Bacteriological (Biological) and Toxin Weapons and on Their Destruction, commonly called the Biological Weapons Convention. Over 140 countries have since added their ratification. This treaty prohibits the stockpiling of biological agents for offensive military purposes, and also forbids research into such offensive employment of biological agents. However, despite this historic agreement among nations, biological warfare research continued to flourish in many countries hostile to the United States. Moreover, there have been several cases of suspected or actual use of biological weapons. Among the most notorious of these were the "yellow rain" incidents in Southeast Asia, the use of ricin as an assassination weapon in London in 1978, and the accidental release of anthrax spores at Sverdlovsk in 1979.
Testimony from the late 1970's indicated that Laos and Kampuchea were attacked by planes and helicopters delivering aerosols of several colors. After being exposed, people and animals became disoriented and ill, and a small percentage of those stricken died. Some of these clouds were thought to be comprised of trichothecene toxins (in particular, T2 mycotoxin). These attacks are grouped under the label "yellow rain". There has been a great deal of controversy about whether these clouds were truly biological warfare agents. Some have argued that the clouds were nothing more than feces produced by swarms of bees.
In 1978, a Bulgarian exile named Georgi Markov was attacked in London with a device disguised as an umbrella. The device injected a tiny pellet filled with ricin toxin into the subcutaneous tissue of his leg while he was waiting for a bus. He died several days later. On autopsy, the tiny pellet was found and determined to contain the toxin. It was later revealed that the Bulgarian secret service carried out the assassination, and the technology to commit the crime was supplied by the former Soviet Union.
In April, 1979, an incident occurred in Sverdlovsk (now Yekaterinburg) in the former Soviet Union which appeared to be an accidental aerosol release of Bacillus anthracis spores from a Soviet Military microbiology facility: Compound 19. Residents living downwind from this compound developed high fever and difficulty breathing, and a large number died. The Soviet Ministry of Health blamed the deaths on the consumption of contaminated meat, and for years controversy raged in the press over the actual cause of the outbreak. All evidence available to the United States government indicated a massive release of aerosolized B. anthracis spores. In the summer of 1992, U.S. intelligence officials were proven correct when the new Russian President, Boris Yeltsin, acknowledged that the Sverdlovsk incident was in fact related to military developments at the microbiology facility. In 1994, Meselson and colleagues published an in-depth analysis of the Sverdlovsk incident (Science 266:1202-1208). They documented that all of the cases from 1979 occurred within a narrow zone extending 4 kilometers downwind in a southerly direction from Compound 19. There were 66 fatalities of the 77 patients identified.
In August, 1991, the United Nations carried out its first inspection of Iraq's biological warfare capabilities in the aftermath of the Gulf War. On August 2, 1991, representatives of the Iraqi government announced to leaders of United Nations Special Commission Team 7 that they had conducted research into the offensive use of Bacillus anthracis, botulinum toxins, and Clostridium perfringens (presumably one of its toxins). This open admission of biological weapons research verified many of the concerns of the U.S. intelligence community. Iraq had extensive and redundant research facilities at Salman Pak and other sites, many of which were destroyed during the war.
In 1995, further information on Iraq's offensive program was made available to United Nations inspectors. Iraq conducted research and development work on anthrax, botulinum toxins, Clostridium perfringens, aflatoxins, wheat cover smut, and ricin. Field trials were conducted with Bacillus subtilis (a simulant for anthrax), botulinum toxin, and aflatoxin. Biological agents were tested in various delivery systems, including rockets, aerial bombs, and spray tanks. In December 1990, the Iraqis filled 100 R400 bombs with botulinum toxin, 50 with anthrax, and 16 with aflatoxin. In addition, 13 Al Hussein (SCUD) warheads were filled with botulinum toxin, 10 with anthrax, and 2 with aflatoxin. These weapons were deployed in January 1991 to four locations. In all, Iraq produced 19,000 liters of concentrated botulinum toxin (nearly 10,000 liters filled into munitions), 8,500 liters of concentrated anthrax (6,500 liters filled into munitions) and 2,200 liters of aflatoxin (1,580 liters filled into munitions).
The threat of biological warfare has increased in the last two decades, with a number of countries working on the offensive use of these agents. The extensive program of the former Soviet Union is now primarily under the control of Russia. Former Russian president Boris Yeltsin stated that he would put an end to further offensive biological research; however, the degree to which the program was scaled back is not known. Recent revelations from a senior BW program manager who defected from Russia in 1992 outlined a remarkably robust biological warfare program, which included active research into genetic engineering, binary biologicals and chimeras, and industrial capacity to produce agents. There is also growing concern that the smallpox virus, now stored in only two laboratories at the CDC in Atlanta and the Institute for Viral Precautions in Moscow, may be in other countries around the globe.
There is intense concern in the West about the possibility of proliferation or enhancement of offensive programs in countries hostile to the western democracies, due to the potential hiring of expatriate Russian scientists. It was reported in January 1998 that Iraq had sent about a dozen scientists involved in BW research to Libya to help that country develop a biological warfare complex disguised as a medical facility in the Tripoli area. In a report issued in November 1997, Secretary of Defense William Cohen singled out Libya, Iraq, Iran, and Syria as countries "aggressively seeking" nuclear, biological, and chemical weapons.
Finally, there is an increasing amount of concern over the possibility of the terrorist use of biological agents to threaten either military or civilian populations. There have been cases of extremist groups trying to obtain microorganisms that could be used as biological weapons. The 1995 sarin nerve agent attack in the Tokyo subway system raised awareness that terrorist organizations could potentially acquire or develop WMD's for use against civilian populations. Subsequent investigations revealed the organization had attempted to release botulinum toxins and anthrax on several occasions. The Department of Defense has been leading a federal effort to train the first responders in 120 American cities to be prepared to act in case of a domestic terrorist incident involving WMD. The program will be handed over to the Department of Justice on October 1, 2000. In the past two years, first responders, public health and medical personnel, and law enforcement agencies have dealt with the exponential increase in biological weapons hoaxes around the country.
Certainly the threat of biological
weapons being used against U.S. military forces and civilians is broader
and more likely in various geographic scenarios than at any point in our
history. Therefore, awareness of this potential threat and education of
our leaders, medical care providers, public health officials, and law enforcement
personnel on how to combat it are crucial.\
