What is a common characteristic of biological agents?

Biological agents are often characterized by their lack of distinct sensory attributes, meaning they typically have no odor, taste, or color. This characteristic is crucial because it makes detecting these agents challenging without specialized equipment. Unlike chemical agents that may have identifiable scents or colors, biological agents such as bacteria, viruses, or toxins can remain undetected in an environment, increasing the risk of exposure and outbreak.

Understanding this property is important in the context of emergency response, as responders must rely on monitoring equipment and lab analysis to identify biological threats instead of sensory perception. This distinction highlights why safety protocols and preparedness measures are essential when dealing with potential biological agents in emergency situations.
