What are the signs of an infected wound?

Possible signs of wound infection include increasing redness, warmth, swelling, pain, pus-like drainage, an unpleasant odor, delayed healing, fever, or red streaks near the wound. A clinician should evaluate these changes promptly, especially in someone with diabetes, poor circulation, or a weakened immune system.

Changes around the wound

Some tenderness and mild redness can occur early in normal healing. Infection becomes more concerning when redness expands, pain increases instead of improving, the skin feels unusually warm, or swelling develops around the wound.

  • Redness spreading beyond the wound edge
  • Increasing warmth, tenderness, or throbbing pain
  • New swelling or hardening of the surrounding skin
  • Wound edges that are breaking down rather than closing

Drainage, odor, and tissue changes

Drainage should be considered together with the wound's appearance and the patient's overall condition. Thick yellow, green, brown, or pus-like drainage; a new strong odor after cleansing; increasing drainage; or new dark tissue can warrant assessment. Drainage color alone cannot confirm infection.

Whole-body warning signs

Fever, chills, unusual fatigue, confusion, rapid breathing, dizziness, or a fast heartbeat may mean an infection is no longer limited to the wound. Older adults may develop confusion or weakness without a high fever.

When to seek urgent help

Seek emergency care for rapidly spreading redness, red streaks, severe or disproportionate pain, confusion, fainting, difficulty breathing, or signs that a limb has become cold, pale, blue, or numb. Do not wait for a scheduled home visit when these symptoms are present.
