Which type of wound carries a higher risk of infection?

• A. Intentional wounds (surgical)
• B. Unintentional wounds (trauma)
• C. Chronic wounds
• D. Thermal burns only

Answer: (B)

Infection risk in wounds rises with contamination, exposure time, and the amount of devitalized tissue. Unintentional wounds from trauma are typically created outside a sterile environment and are more likely to be contaminated with dirt, debris, or foreign material. They may also have delays in cleaning and more tissue disruption, which makes it easier for bacteria to invade and establish infection.

Surgical wounds, by contrast, are planned clean procedures performed under sterile conditions with meticulous technique and often perioperative antibiotics, which reduces infection risk. While chronic wounds and burns can be susceptible to infection because of poor tissue perfusion, necrotic tissue, or barrier loss, the immediate higher risk in the common exam scenario usually lies with traumatic, unintentional wounds.
