Which type of infection is confined to a specific area and appears as a lesion containing pus?

A local infection is characterized by its confinement to a specific area of the body where it produces symptoms such as redness, swelling, warmth, and in many cases, pus. This type of infection occurs when pathogens invade a localized region, leading to the accumulation of pus, which is a thick fluid composed of dead white blood cells, bacteria, and tissue debris. In contrast to systemic infections, which affect the entire body and may lead to widespread symptoms, local infections are restricted to one area, making them easier to treat and manage. Understanding this distinction is important for effective infection control and treatment in barbering practice, especially in contexts such as wounds or skin conditions that may occur during grooming services.
