Symptoms
Classic signs and symptoms of impetigo involve red sores that quickly rupture, ooze for a few days and then form a yellowish-brown crust. The sores usually occur around the nose and mouth but can be spread to other areas of the body by fingers, clothing and towels. Itching and soreness are generally mild.
A less common form of the disorder, called bullous impetigo, may feature larger blisters that occur on the trunk of infants and young children.
A more serious form of impetigo, called ecthyma, penetrates deeper into the skin â causing painful fluid- or pus-filled sores that turn into deep ulcers.
When to see a doctor
If you suspect that you or your child has impetigo, consult your family doctor, your child's pediatrician or a dermatologist.
