👉 Infection, particularly an infectious disease, occurs when a pathogen—such as bacteria, viruses, fungi, or parasites—invades and colonizes a host's body, disrupting normal physiological functions. The body's immune system responds by initiating an inflammatory response to contain and eliminate the invader. However, if the infection is severe or the immune response is compromised, the pathogen can multiply, leading to tissue damage and systemic symptoms. Acknowledging infection involves recognizing the presence of these pathogens and the body's reaction to them, which can range from mild symptoms like fever and fatigue to severe conditions requiring medical intervention. Early detection and treatment are crucial to prevent complications and promote recovery.
