terri-
(Latin: frightful, fearful; fear; fright; literally, causing terror)
Don't confuse this element with other words that are spelled in a similar way; such as, terrestrial or territory.
The term bioterror is often used loosely to describe nuclear, biological, and/or chemical (NBC) terrorism.
The U.S. government is especially worried about the Big Six bioterrorism threats: anthrax, smallpox, plague, tularemia, botulism toxin, and viral hemorrhagic fevers (like the Ebola virus).
While less well-known than the other diseases, tularemia and botulism toxins could conceivably be aerosolized, causing severe respiratory illness and paralysis, respectively.
"Skyscrapers, tunnels, subways, and their requisite heating and air-conditioning systems provide targets and also ways of attack for would-be bioterrorists."
