Bioterrorism
A bioterrorism attack is the deliberate release of viruses, bacteria, or other germs (agents) to cause illness or death in people, animals or plants. These agents are typically found in nature, but it is possible that they could be changed to increase their ability to cause disease, make them resistant to current medicines or to increase their ability to be spread into the environment. Biological agents can be spread through the air, through water or in food.
