Impetigo is a skin infection caused by bacteria. The infection often begins when bacteria that normally can be present on the skin enter a small cut or scratch.

Symptoms of impetigo include honey-colored, crusty, oozing blisters or sores, most often between the upper lip and nose. The blisters commonly occur after a cold. The sores can appear anywhere on the body. Scratching the blisters may spread impetigo to other parts of the body. Impetigo is more common in children than adults.

Impetigo is most often treated with antibiotics.
