Itching is common. Other symptoms are uncommon unless the lesions are widespread. Blisters are present, containing yellow watery liquid, and then they become filled with pus and surrounded by redness. The pus-filled blisters rupture, dry up in the center, and form honey-colored scabs. The lesions vary in size from 1/8 of an inch to several inches. If impetigo is not adequately treated, it can cause a kidney infection, and occasionally, rheumatic fever. |

Definition and cause |
Impetigo is an infection of the outer layers of skin that is seen most often in children. It is most prevalent during the hot, humid summer months or in early fall. Germs causing impetigo are streptococci (strep) and staphylococci (staph). It may be spread by direct contact with infected persons and possibly by insects, or it can be a result of strep throat. It is 2-5 days from the time the germ is introduced until infection develops. The untreated child is contagious until lesions heal. Treatment shortens the length of time the infection can be spread. |

Treatment |
Soak and gently scrub the lesions with warm water and an antibacterial soap three times a day to soften and remove scabs. Trim fingernails to prevent further spread. Apply an antibiotic ointment such as Bacitracin, Triple Antibiotic Ointment, or other over-the-counter equivalent three times a day following the cleansing procedure. Take precautions to prevent the spread to other persons. Good handwashing technique is an excellent preventive measure. Exclusion from school or daycare is not usually necessary if the lesions can be covered. Lesions of the face, nose, or mouth, multiple lesions, or large lesions that cannot be covered are indicators that the child should not attend school or daycare until 48 hours after starting antibiotic therapy. Failure to improve in 5-7 days means the child should be seen by his doctor. |
