In spite of the positive influences of biological/chemical weapons, there are many more negative effects, including the immense terrorist threat. Because biological and chemical weapons can be a seemingly effortless construction, the possibility of terrorist use is always evident: “If a bioterrorist attack were to happen, Bacillus anthracis, the bacteria that causes anthrax, would be one of the biological agents most likely to be used" (“Anthrax”). According to the CDC, anthrax is a likely bioterrorist weapon for a few main reasons: including the former use, the spores can be found in nature or produced in a scientific lab, the spores are microscopic and near impossible to detect, and the spores can be put into many environments and still …show more content…
thrive. Second, biological and chemical weapons are very simple to use and transport. Because the administration of these weapons are so easy, small and large targets are not hard for terrorists to harm, or even kill. These weapons can be small, light, and undetectable to security systems.
Many scientists, including Fred Milanovich, have been working to eliminate this risk: “A key factor limiting the nation's ability to protect against a biological attack has been the state of biodetector technology. Only now is technology becoming available that permits identification of biological organisms within minutes, when concentrations are low but often still dangerous” (Walter). Biological and chemical weapons can be snuck into many high security places; high value people and places could become an easily accessible target for terrorists to send a message. Although this technology has been developed to detect these risks, it only detects the toxin when it is suspected, and is not accessible for public use. Also, the time between infection and detection of the toxin is a weapon in and of itself: “Many biological agents are contagious, and during this lag time, infected persons could continue to spread the disease, further increasing its reach. Hundreds or even thousands of people could become sick or die if a biological attack were to occur in a major metropolitan area” (Walter). If a terrorist was able to weasel a toxin into popular areas, or onto popular people, by the time detection occurred the agent would have been spread to a large
number of people. Furthermore, attacks have been present as the Islamic State militants(ISIS) gained power. In September - October of 2014 Dhuluiya and Balad, Iraq were attacked using chlorine and mustard gas, leaving about 40 people injured (“Summary). The use of these toxins becomes a serious threat. As people realize the success terrorist groups have had with these weapons, they begin to question their safety, and if they have the ability to effect the United States. Once the toxin is noticed, the government will try to track down all people who were infected; between their infection, the disclosure, and being found themselves, the civilians would have infected more people. This chain reaction could be disastrous and is a great plan for terrorist attacks.

Though biological weapons have been available for under a century, there is a long history of their use between 1914 and 1972. Chemical warfare was first introduced in 1914 at the beginning of World War I. Because of the new style of warfare with automatic weapons, trenches were dug out from the ground to defend against a slaughter. The introduction of this issue caused us to invent weapons such as the grenade, flame thrower, and finally, biological weapons. Biological weapons were distributed by hoses, grenades, and aerial attacks. By doing this, we eliminated many enemy trenches and saved a large amount of Ally lives. (Menace)
Anthrax is one of the most preferred biological warfare agents for many highly identified reasons. First, anthrax is extremely lethal. Anthrax can contain up to 100 million lethal doses in just one gram of anthrax spores, which is 100,000 times more lethal than any other biological warfare agent. It is also known that inhalation anthrax is almost always fatal if the symptoms are allowed to progress without any treatment. Anthrax is also the silent and invisible killer. On top of the fatality rate of anthrax, there are also very low barriers to produce the biological weapon. Anthrax spores are very easy to produce in large quantities, and the process of production is very inexpensive. Also, there is plenty of available information on how to weaponize anthrax and not a whole lot of technology is needed to be able to produce anthrax. Anthrax is also easy to weaponize because it is extremely stable as a dry powder in the form of spores. These spores can live for decades and still be very lethal to the human body. Anthrax can be put into an aerosol form disseminated into a spray can, and it can also be freeze-dried into a bomb. Presently anthrax is the most preferred biological agent is because we have no accurate detection capability.

There are many factors that play into how a situation should be handled. For a start, the initial approach to a bioterrorist scene determines the outcome of the fatality of the situation. Also, the technique used to spread an infection is vital because it determines what method would be the best as a counter attack. For example, Robert Bourke states in his book Counter-Terrorism for Emergency Responders that, “vapor release from nerve or blister agents will
From 166 A.D. to 180 A.D., The Antonine Plague spread around Europe devastating many countries. This epidemic killed thousands per day and is also known as the modern-day name Smallpox. It is known as one of deadliest plagues around the world.

Since the end of the Persian Gulf War, the United States along with the United Nations has struggled with Saddam Hussein to locate his “weapons of mass destruction”. Saddam’s persistence and dubious manner towards the United States military has raised concern for military protection. To combat biological threats, Secretary of Defense William Cohen implemented a mandatory military wide vaccination of all military members. Since the inception of the program, the program has been the subject of criticism by military members, Veteran Associations, Doctors, and many Senators on Capital Hill. The criticisms have stirred questions regarding the safety and effectiveness of the vaccine. Questions that the military has not given clear answers to. Until the many questions regarding the vaccine are answered, service members should not be forced to undergo the vaccination program against anthrax.
The rapid pace of vaccine development convinces people that they are safe from the infectious diseases. Unfortunately, the anthrax outbreak in 2001, having killed five people, reveals the vulnerability of the public health, suggesting that further research on contagious epidemics should be developed abruptly. In response to this issue, the National Institute of Allergy and Infectious Diseases (NIAID) granted Boston University a $128 million funding for the construction of a new leading facility known as the National Emerging Infectious Diseases Laboratory (NEIDL or BU Biolab), which would be sited on the Boston University Medical Campus, to battle against contagious ailments. Besides conducting research on infectious diseases, the BU Biolab will also perform research to prepare for bioterrorism (Le Duc). According to the Center for Disease Control, there are four levels of increasing of containment for research on infections ranging from Biosafety Levels 1 through 4 (BSL-1 to BSL-4). While much of the research on epidemics is done in laboratories with BSL-2 to BSL-3, the BU Biolab, with the highest level of precaution, BSL-4, will conduct research on rare contagious epidemics including anthrax, ebola, and plague, which are usually life threatening.
One of the world’s most dreaded plagues for centuries, smallpox is now eradicated. Vaccination programs were pushed worldwide by the World Health Organization (WHO) and the disease was eliminated from the world. This push resulted in the last naturally occurring case in the world being almost 40 years ago. Once eradicated the once routine or mandatory vaccinations were stopped for the general public and it was deemed no longer necessary to prevent the disease. Although currently eradicated worldwide, two medical laboratory stockpiles still remain in Russia and the United States. With these stockpiles in existence the possibility of bio terrorism emerges and fear of these stockpiles getting into the wrong hands and being weaponized for use against the public is rising. The smallpox disease is highly contagious and easily communicable and currently there is no cure for this disease. If reintroduced, an epidemic would be devastating worldwide.
The Black Death pandemic had affected almost everyone who lived in that time, everyone wanted to know if there was a cure. People of that time were constantly dreading the idea that it was Gods' punishment. The plague entered south-western England in the summer of 1348 and it stuck Bristol with shocking numbers. Bristol was the second largest city in Britain and was the principal port of entry for the west country. Within it lived upwards of 10,000 souls, tightly packed together in conditions that were not altogether sanitary. The foul conditions was as true of Bristol as it was in any other medieveal town, if not more so because its size of population. People had the tendency to pore their chamberpots ,which was a bowl that people used as
Chicken pox is not an Entrée that is served at one’s family holiday dinner party. Chicken pox is an extremely contagious disease caused by the Varicella zoster virus. Chicken Pox is not a disease that is known to affect other animals or insects. Unlike other diseases, where human and other animal close interaction causes the exchange of virus and disease this disease did not come from a human-chicken interaction. The name chicken pox has been stuck for generations; there are many theories behind its name. Chicken pox could sneak up on its young victims in the form of an innocent touch, or by inhaling tiny particles from a cough, or sneeze which then enters the respiratory tract. Once the virus attaches itself to it gracious, and unwilling host cells it causes a crimson rash that could be located on different parts of the body. The rash is highly irritating which makes it almost impossible not scratch. In the United States each year about 5,000 to 9,000 people are hospitalized, and around 100 people die from the microbe Varicella zoster that causes chicken pox.
Biological warfare is infecting humans, animals and plants with a disease intentionally. This act is performed by introducing a bacterium or a virus into such an environment where population is not prepared to combat the infection caused by a pathogen. During warlike situations these biological weapons result in potent killing of humans, livestock, plants and pets. The infection causing bacteria or viruses are genetically or conventionally modified to have resistance to antibiotics. These pathogens could easily spread further through air, water, touch and food. Bacillus anthracis commonly known as anthrax is a bacterium which is when exposed to humans, releases toxin and can be fatal if not treated timely.
Throughout the progression of mankind, there has always been a need to become superior in tactics and technology over an opponent. It did not take long for man to discover the effective and deadly tactic of Bioterrorism, which is the deliberate release of viruses, bacteria or other germs used to cause illness or death in people, animals, or plants. As time passes, everything about bioterrorism becomes more and more sophisticated, making it very difficult to combat with. By examining the history of bioterrorism, one can learn how military forces utilize this deadly weapon.
Department of State, the perception of people on biosecurity threat has evolved as they “see the world in terms of a multipolar, multi-threat environment”. It further stated that “biorisk and matrices to measure the weighted value of each risk have become the norm, and biosecurity and biosafety have come to encompass the use of proper safety measures and facility specifications, as well as the proper training of employees to ensure not only their own safety but that of the public at large.”
