Biological agents are viruses, bacteria or other germs that can be found naturally occurring in the environment. An act of bioterrorism involves the deliberate release of harmful biological agents to cause illness or death in people, animals or plants. Bioterrorism agents can be spread through the air or put into food or water, and can be extremely difficult to detect. Some biological agents, like the smallpox virus, can be spread from person to person, while some, like anthrax, cannot.
