👉 Infection refers to the process by which a pathogen, such as a virus, bacterium, fungus, or parasite, enters and takes control of a host's body, leading to disease. This occurs when the pathogen breaches the body's natural barriers, like the skin or mucous membranes, and begins to multiply or cause harm. The immune system responds to the invasion by mounting an attack, but if the pathogen is too virulent or the host's defenses are weakened, the infection can progress, resulting in symptoms and potential complications. Effective treatment often involves targeting the pathogen directly or supporting the body's natural defenses to restore health.
