The first signs of impetigo can usually be seen around the mouth and nose in the form of an itchy reddish rash with small blisters. The blisters are filled with water or pus and burst easily. Once they have burst, yellowish crusts form. These fall off after some time without scarring. As well as on the face, impetigo can occur on the arms and legs.

In rare cases, larger blisters develop and don't break open as quickly. This type of impetigo (bullous impetigo) affects the neck and torso, and may be found in the armpits or in the groin area.
The main symptom of impetigo is reddish sores, often around the nose and mouth. The sores quickly rupture, ooze for a few days and then form a honey-colored crust. Sores can spread to other areas of the body through touch, clothing and towels. Itching and soreness are generally mild.
