Bioterrorism

<B>Bioterrorism:</B> Terrorism using biologic agents.

Biological diseases and the agents that might be used for terrorism have been listed by the US Centers for Disease Control and Prevention (the CDC).

The list includes a sizable number of 'select agents' -- potential weapons whose transfer in the scientific and medical communities is regulated to keep them out of unfriendly hands.</P> These 'select agents' are very varied.

They comprise viruses, bacteria, rickettsiae (micro-organisms that have traits common to both bacteria and viruses), fungi and biological toxins.</P> The CDC has classified all of these 'select agents' according to the degree of danger each agent is felt to pose into one of three categories:</P> > ><B>Category A Biological Disease:</B> -- The U.S.

public health system and primary health-care providers must be prepared to address varied biological agents, including pathogens that are rarely seen in the United States.

High-priority agents include organisms that pose a risk to national security because they > >can be easily disseminated or transmitted person-to-person; >cause high mortality, with potential for major public health impact; >might cause public panic and social disruption; and >require special action for public health preparedness.
