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-coloured, 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.
