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 yellow, crusty, oozing blisters
or sores. 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.
