An infection that is confined to a small area, often indicated by a pus-filled lesion, is called?

• A. Local infection
• B. General infection
• C. Asymptomatic carrier
• D. Universal precautions

Answer: (A)

The key idea is recognizing infections by how widespread they are. A pus-filled lesion signals an infection that is restricted to a specific spot—the area around the wound shows the active battle between bacteria and immune cells, causing local symptoms like redness, swelling, and pus. That describes a local infection.

In contrast, a general or systemic infection would have spread beyond the initial site to involve the whole body or multiple systems, often bringing systemic signs such as fever, overall malaise, and widespread inflammation. An asymptomatic carrier is someone who harbors the infectious agent without showing symptoms, not a description of the infection’s location or scope. Universal precautions are safety practices to prevent transmission, not a type of infection.

So the infection confined to a small area with a pus-filled lesion is best described as a local infection.
