What is an example of an Infectious agent?

Infectious agents are defined as microorganisms that can cause disease in a host. This category includes various types of pathogens such as bacteria, viruses, fungi, and parasites. A pathogenic microorganism is specifically one that has the potential to cause illness or infection, making it a clear example of an infectious agent. Understanding this classification is crucial for handling hazardous materials responsibly, especially in environments where exposure to pathogens may occur.

Other options list substances that can cause various health issues but do not fall under the definition of infectious agents. Chemicals that cause burns, substances leading to allergic reactions, and toxins that result in poisoning can all cause harm but are not considered infectious agents as they do not involve microorganisms. Focusing on the nature of the example provided is essential for correctly identifying infectious agents in the context of hazardous materials.
