A lesion containing pus, confined to a particular part of the body is known as what?

A lesion that contains pus and is confined to a specific area of the body is classified as a local infection. This type of infection is characterized by inflammation and the presence of pus, which is a collection of dead white blood cells, bacteria, and tissue debris. Local infections usually occur when pathogens invade tissues and provoke an immune response, leading to localized symptoms such as redness, swelling, warmth, and pain in the affected area.

In contrast, systemic infections involve the entire body or multiple organ systems and are characterized by more generalized symptoms such as fever and fatigue. Chronic infections persist over a long period and may exhibit less severe symptoms, while acute infections present quickly and are often more intense but of shorter duration compared to chronic infections. Thus, the definition and characteristics of a local infection align perfectly with the description of a lesion containing pus confined to a particular part of the body.
