Bioterrorism
Case Study on Bioterrorism
Create a scenario of a hypothetical bioterrorist attack involving botulism or plague. Your scenario should include characteristics that are more indicative of an intentional outbreak than a natural outbreak.
Yersinia pestis is the causative agent of plague, an enzootic vectorborne disease usually infecting rodents (rats) and fleas and humans can become infected after being bitten by fleas that have fed on infected rodents; in humans, the disease usually occurs in the form of bubonic plague (Riedel, 2005). However, there are many other forms of this disease that can also be created artificially. In some cases, the infection can spread without the need for infestation and through oral pathways. This from of the disease can be spread to the lungs via the bloodstream and causes secondary pneumonic plague.
Plague is also recognized as a potential agent of bioterrorism because of the person-to-person transmission has been described for pneumonic plague but is rare in primary bubonic plague. Bubonic plague can usually be treated successfully with antibiotics; however, pneumonic plague develops rapidly and carries a high fatality rate despite immediate treatment with antibiotics. For these reasons it has been a potential threat as a biologic weapon for many...
If one of these agents would be released in a city such as New York City, the condition could spread rapidly.
2. Describe how the outbreak characteristics would have been different in the above scenario if the outbreak had been natural rather than intentional.
The natural forms of the bubonic plague are easily treatable by antibiotics. However, it is likely that a form of the plague that was used for a bioterrism incident would be significantly different from the naturally occurring form of the disease. One consensus study performed by the Center for Disease Control (CDC) found that an aerosolized plague weapon could cause fever, cough, chest pain, and hemoptysis with signs consistent with severe pneumonia 1 to 6 days after exposure; Rapid evolution of disease would occur in the 2 to 4 days after symptom onset and would lead to septic shock with high mortality without early treatment and prophylaxis with streptomycin or gentamicin or the tetracycline or fluoroquinolone classes of antimicrobials would be advised (Inglesby, 2000). Therefore, even though there are treatments available, these treatments would unlikely be readily available at most treatment centers and therefore this type of bioterrorism could cause severe damage before the needed treatments are onsite.

smallpox as a weapon against societies. The writer explores the viability of using smallpox as a weapon as well as some of the things societies have done to prepare for such a possibility. In addition the education of the American public for such an attack is discussed. There were seven sources used to complete this paper. Bioterrorism has been a concern of the United States for many years. During most
Threat of Bioterrorism There are many reasons to believe that overruling of the possibility of bioterrorism in the country is a serious mistake. In fact, it is practically impossible to ignore the fact that in the recent past, there has been an escalation in the cases of bioterrorist attacks. However, this has not always been the case and many people were in denial of the possibility of anyone using such measures
Smaller particles follow the fluid streamlines and exit the sample." (NATIBO, 2001) The method of operation of a "bubbler or impinger" is through "drawing aerosols through a current inlet tube and jet. Usually the jet is submerged in the liquid contained in the sampler." (NATIBO, 2001) the aerosol particles become capture din the base of the jet by the surface of the liquid as the air moves through the liquid.
Data gaps must also be acknowledged, and approximated if at all possible. When approximating, conservative estimates should be made -- in other words, when assessing an individual's exposure to second-hand smoke, assuming exposure over a 24-hour period (the maximum possible exposure to the environment) rather than the minimum, is usually preferred. or, in the case of childhood exposure to lead paint, even if this cannot be confirmed, if the individual
Air traffic has continued to increase and it now constitutes a considerable proportion of the travelling public. The amount of long-hour flights has increased significantly. Based on the International Civil Aviation authority, air traffic can be anticipated to double amid till 2020. Airline travel, especially over longer distances, makes air travelers vulnerable to numerous facets that will impact their health and well-being. Particularly, the speed with which influenza spreads and
Weapons of Mass DestructionIntroductionThis paper addresses the methodology, and discusses the findings of the research. It also offers conclusions and recommendations for addressing the problem of WMD prevention. It applies the theoretical perspectives of Taylor and Follett and also looks at the impact of having an ethical framework in place. It concludes with recommendations for establishing an international effort to bring about the collaboration needed to prevent WMD proliferation.MethodologyThe method
