What is Bioterrorism?

According to the Center for Disease Control, a bioterrorism attack is "the deliberate release of viruses, bacteria, or other germs (agents) used to cause illness or death in people animals or plants." However, this simple definition is insufficient in that it does not contain any information that would aid the general public in preparing for and responding to a possible bioterrrorism attack. How can we arm ourselves against such a threat? What are examples of bioterrorism that have already occurred here in the U.S. and around the world? These are questions I will attempt to answer in order to define the term "bioterrorism" more wholly.
