What are pathogens?

Pathogens are specifically defined as microorganisms that can cause infection and disease in their host. This group includes a variety of agents such as bacteria, viruses, fungi, and parasites that have the potential to disrupt normal bodily functions and lead to various health issues. Understanding pathogens is crucial in the field of infection control, as it allows healthcare professionals to identify, manage, and prevent infections effectively.

Microorganisms that are harmless or those that assist in digestion do not fall under the definition of pathogens, as they either play beneficial roles or are part of the normal flora without causing disease. Recognizing the characteristics of pathogens helps in developing strategies for aseptic techniques and infection prevention in clinical settings.
