Signs and symptoms of burns and infection

Burn

• First-degree burns are red, swollen, and painful. The burned area whitens (blanches) when lightly touched but does not develop blisters.
• Second-degree burns are pink or red, swollen, and painful, and they develop blisters that may ooze a clear fluid. The burned area may blanch when touched.
• Third-degree burns usually are not painful because the nerves have been destroyed. The skin becomes leathery and may be white, black, or bright red. The burned area does not blanch when touched, and hairs can easily be pulled from their roots without pain.

Infection

• Change in color of the burnt area or surrounding skin
• Purplish discoloration, particularly if swelling is also present
• Change in thickness of the burn (the burn suddenly extends deep into the skin)
• Greenish discharge or pus
• Fever
