👉 Infection, in medical terms, refers to the process by which a pathogen—such as bacteria, viruses, fungi, or parasites—invades and establishes itself within a host organism, leading to disease. This occurs when the pathogen breaches the body's natural barriers, such as the skin or mucous membranes, and begins to multiply or cause harm. The body's immune system responds to the infection by mounting an immune defense, which can sometimes fail to fully eliminate the pathogen, resulting in persistent infection. Conviction in this context means a strong belief or certainty that the infection is present and actively causing harm, often leading to appropriate medical intervention to prevent further complications or disease progression.
