Untreated Burn Infection: Risks, Complications, and What to Do

An infected burn left untreated can progress to life-threatening systemic complications.

Major Complications

• Sepsis: Bacteremia → systemic inflammatory response → septic shock, multi-organ failure, death.
• Necrotizing fasciitis: Rapid spread along fascial planes → extensive tissue necrosis → emergent debridement/amputation.
• Tetanus: Clostridium tetani spores in devitalized tissue → neurotoxin → trismus, opisthotonus, autonomic instability; high mortality without antitoxin and ICU care.

Additional Sequelae

• Disfigurement, contractures, functional loss
• Chronic pain, neuropathic pain
• Psychological trauma (PTSD, body image distress)

Immediate Action

Seek emergency medical care for any signs of burn infection: increasing redness, warmth, swelling, purulent discharge, foul odor, fever, worsening pain, or red streaks. Early antibiotics, wound care, and tetanus prophylaxis prevent progression.
