¶ … Recovery Plan: Biological Attack in the U.S. Congress
The havoc and deaths caused by the weaponized anthrax spores that were mailed to members of the U.S. Congress following the attacks of September 11, 2001 and the repeated attempted uses of botulinum toxin on U.S. Naval bases make it abundantly clear that governmental offices are vulnerable to biological pathogens. These agents have been and likely will be used by terrorists again to achieve their goals of bringing harm to the United States and it interests at home and abroad. The hypothetical comprehensive recovery plan developed in this project is in response to this type of food-borne pathogen attack and takes place in the cafeteria situated in the Rayburn House Office Building in the U.S. Congressional complex in Washington, D.C. which serves members of Congress, staff members and visitors. The scenario begins with the telephonic notification to the Capital Police that all of the food in the Rayburn House Office Building cafeteria has been infected with clostridia, a major source of botulinum toxin. Although the cafeteria was closed when this notification was received, there are several immediate steps that must be taken in response and these are described in the recovery plan below, followed by a summary of the research and important findings in the conclusion.
Review and Discussion
Description of the specific agent used in the attack and the effects of the agent on victims, and surrounding areas.
The clostridia group is a particularly virulent pathogen and can cause a number of adverse health outcomes, including death. According to Lathe (2006), the group of clostridia has been closely associated with a wide range of diseases, including gangrene, botulism, and tetanus, depending on the strain that is involved. Likewise, Rooney, Swezey, Friedman, Hecht and Maddox (2006) report that, "Clostridium perfringens is a spore-forming, gram-positive anaerobe that is found in soil and in the gastrointestinal tract of vertebrates. Pathogenic strains of C. perfringens cause a variety of human and animal diseases including food poisoning, antibiotic-associated diarrhea, gas gangrene, necrotic enteritis, necrotizing colitis, sudden death syndrome, and enterotoxemia" (p. 2081).
The clostridia group can induce disease in both non-food-borne and food-borne forms, and the food-borne form illness is the result of strains that carry a chromosomal enterotoxin gene with symptoms of the milder forms of the diseases typically persisting between 24 and 48 hours (Rooney et al., 2006). Farm-animal meat is a particularly suspect source of this pathogen (Rooney et al., 2006). If the clostridia strain involved in this event was botulinum toxin, though, the outcomes would be far more serious because this is among the most deadly substances known to humans (Dando, 2001). According to this authority:
When enough [botulinum] toxin is inhaled or ingested to produce clinical symptoms, there is a high fatality rate, death generally being rapid and medical treatment ineffective…. Specific anti-toxin is effective if administered before symptoms appear. An effective toxoid is available for immunization prior to exposure. The agent is not transmitted man to man. In short, this is a lethal agent that is not contagious and is fast acting in high doses. (Dando, 2001, p. 19)
Although botulism can be caused by improper food handling or preparation and cause serious illness or even death, a weaponized version of the pathogen would be much more lethal (Dando, 2001). As noted above, although the botulinum toxin is not contagious, it is possible to spread a purified, dried preparation of the pathogen via wind-borne routes (Dando, 2001). The potential for this eventuality must be considered in any such episode and would make evacuation and quarantine of surrounding buildings, such as the three Senate and three House office buildings an immediate requirement until the source of the contamination was confirmed with absolute certainty. In this regard, Hilborne and Golomh emphasize that, "Botulinum toxin can be delivered by the aerosol route; this method affords broader area spread, greater casualties, and less loss of the agent than introducing it into the food or water supplies. Because toxins are environmentally stable, this is the most probable route to deliver this agent as a biological weapon" (1998, p. 91). There are some typical symptoms that can be used to help first responders identify victims of such an attack, and these are discussed further below.
Symptoms victims will experience and display
Given its potential lethality and fast action, the symptoms that victims will tend to experience and display following infection by the botulinum toxin can be expected to be serious. This point is made by Dando who stresses, "The response of an affected victim is described as very severe" (2001, p. 20). Although potential paralysis is a common feature to all such infections, other symptoms include dry mouth, inability to focus (perceived as blurred vision), and diplopia in milder cases of infection, but severe cases of infection can cause dysphonia, dysarthria, dysphagia,...
U.S. National Strategy What three United States national interests do you think will be at great risk over the next five years? Describe those interests and identify which instruments of national power can be leveraged to protect or advance those national interests and how those instruments can be used. As President Obama stated in his addresses to Congress in February 2009, the most important problem that the country faced was the economy,
This as an important moment in the history of the Cold War because it marked the start of a new series of talks between the Palestinians and the Israeli side. This moment also proved the importance of the State Secretary in relation to the issues of foreign policy and the international community. At this moment, some of the most important cabinets in the executive concern issues such as internal affairs
National Preparedness Goal National Preparedness, the Presidential Policy Directive #8 (PPD-8), gives a description of the approach of the United States (U.S.) in the area of being prepared for threats and hazards posing the highest risk to American security. The whole national community shares the responsibility of national preparedness. Contribution and participation is required from every person including communities, individuals, faith-based organizations, and local, state and federal governments. The society will
Emergency management is also a vital part to the planning for a disaster. Training will have to be conducted at periodic intervals to maintain the preparedness of the emergency response team and to evaluate the condition and the operational difficulties if any that may arise due to the equipment being used. The procedures will have to be critiqued and constantly evaluated to determine if a better, safer or more efficient
Such equipment should be adequate to ensure personnel are protected from chemical exposure to the eyes, skin, and respiratory tract. PPE may be upgraded or downgraded by the site industrial hygienist, HSM, or qualified Site Safety Officer based upon site conditions and air monitoring results (Levin, et al., 2002) Work practice and administrative controls Administrative controls or work practice controls are changes in work procedures such as written safety policies, rules,
Decontamination Plan One major challenge facing the U.S. Homeland security is how to protect the nation's airports. The most striking thing is that the U.S. airports have continued to be vulnerable despite the enhanced security measures that have been implemented therein after the terrorist attack that occurred on September 11, 2002(Lenckus, 2011). In this paper, I will present and explain the plan and strategies for decontaminating two of the nation's airports,
