Impetigo is a bacterial skin
infection that is caused by strep or staph 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. These most often develop 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.
