Which of the following is a sign of wound infection?

• A. Redness
• B. Numbness
• C. Itching
• D. Bruising

Answer: (A)

Redness around a wound reflects the body's inflammatory response as immune cells rush to the area. This increased blood flow causes the familiar red appearance and is often accompanied by warmth, swelling, pain, and sometimes pus or fever when an infection is present. In clinical and field settings, new or spreading redness that persists or worsens is a key warning sign of possible infection and warrants care. Numbness points to nerve injury or poor circulation rather than infection. Itching is usually due to irritation, dry skin, or an allergic reaction during healing, not an infection sign. Bruising indicates bleeding under the skin from trauma, not infection.
