What is defined as an infectious agent capable of causing disease?

The term that is defined as an infectious agent capable of causing disease is "pathogen." Pathogens are organisms such as bacteria, viruses, fungi, and parasites that can invade a host and cause illness. Understanding what constitutes a pathogen is vital in infection control practices, as it helps in identifying potential sources of infection and implementing appropriate measures to prevent the transmission and spread of diseases.

Infection control strategies focus on reducing exposure to pathogens and breaking the chain of infection. Being able to recognize pathogens and their modes of transmission is fundamental to healthcare practices aimed at maintaining safety and minimizing the risk of infection among patients and healthcare workers alike.
