Definition
A biological agent is a bacterium, virus, protozoan, parasite, fungus, or toxin that can be used deliberately to cause disease or death in people, animals, or plants. Think of it like a microscopic weapon. Unlike chemical weapons, biological agents are living organisms that can multiply. This makes them potentially more dangerous and difficult to control. They are often associated with bioterrorism and biowarfare. Imagine it as the ultimate invisible enemy, capable of spreading rapidly and causing widespread harm. 🦠
