What is a pathogen?

A pathogen is defined as an organism that causes disease. This encompasses a variety of microorganisms, including bacteria, viruses, fungi, and parasites, that can invade the body and disrupt normal physiological functions, leading to illness. Understanding pathogens is crucial in fields like sports medicine, as recognizing the types of pathogens that could potentially affect an athlete's health is essential for prevention and management of infectious diseases. For instance, knowledge of how pathogens spread and their impact on the body can help in implementing effective hygiene practices and ensuring a safer environment for athletes.
