Pathogens are defined as what?

• A. bacteria used in sanitation
• B. devices used for therapy
• C. disease causing agents
• D. procedures for patient care

Answer: (C)

Pathogens are disease-causing agents—organisms or infectious particles that can invade a host and lead to illness. This includes bacteria, viruses, fungi, parasites, and prions. Recognizing what pathogens are helps explain why infection-control measures like hand hygiene, sterilization, and appropriate use of personal protective equipment are essential to prevent the spread of illness. The other options describe individuals or tools used in care (such as beneficial bacteria for sanitation, devices for therapy, or procedures for care) rather than the agents that cause disease.
