The document defines bioterrorism as the unlawful use of living organisms or their toxins to cause death or disease in humans, animals, or plants in order to create fear or intimidate for political, religious, or ideological goals. It classifies potential bioterrorism agents into 3 categories based on their ease of transmission, mortality rate, and impact on public health. Category A agents are considered the highest priority as they can easily spread and cause high mortality. The document outlines indicators of a potential bioterrorism event and steps medical professionals should take to prepare for and respond to such an attack.

I don't have the evidence to prove that God doesn't exist, but I so strongly suspect he doesn't that I don't want to waste my time. -Isaac Asimov BIOTERRORISM DEFINITION The unlawful use, or threatened use, of microorganisms or toxins derived from living organisms to produce death or disease in humans, animals, or plants. The act is intended to create fear and intimidate governments or societies in the pursuit of political, religious, or ideological goals. CLASSIFICATION SYSTEM Public Health impact criteria based on: •Morbidity and mortality •Delivery potential •Public perception (fear, civil disruption) •Public health preparedness needs CDC CLASSIFICATION CATEGORY A CATEGORY B CATEGORY C Can be easily disseminated or transmitted person-to-person Are moderately easy to disseminate EMERGING PATHOGENS THAT COULD BE ENGINEERED FOR MASS DISSEMINATION IN THE FUTURE Cause high mortality, with potential for major public health impact Cause moderate morbidity and low mortality Might cause public panic and social disruption Require special action for public health preparedness Require specific enhancements of CDC's diagnostic capacity and enhanced disease surveillance Variola major (smallpox) Bacillus anthracis (anthrax) Yersinia pestis (plague) •Clostridium botulinum toxin (botulism) •Francisella tularensis (tularaemia) •filoviruses •Ebola hemorrhagic fever Coxiella burnetti (Q fever); •Brucella species (brucellosis) •Burkholderia mallei (glanders) •alpha viruses •Venezuelan encephalomyelitis •eastern and western equine encephalomyelitis Nipah virus •Hantaviruses •Fick-borne hemorrhagic fever viruses •Tick-borne encephalitis viruses •Yellow fever •Multidrug-resistant tuberculosis - Created with love by Dr. Eashan Srivastava
