This will help keep the child from scratching and spreading the condition. PRECAUTIONS - Impetigo is highly contagious. - Minor scratches and scrapes on the skin may invite impetigo. To avoid infection, clean such minor wounds with soap and water and cover them with a sterile bandage. - Keep an infected child's clothes and linens separate from those used by other family members to help prevent the disease from spreading. Launder the child's clothes frequently. - If home treatment for impetigo is effective, continue it until all the sores have completely healed. It can take a long time to eliminate the condition. - See the doctor if home treatment is not effective. Impetigo is a highly contagious infection of the outer layers of the skin. It is caused by staphylococcus and streptococcus bacteria. The germs are transmitted by direct contact when the child touches either an infected person or something that person has been using--for example, clothing, towels, or toys. The condition appears two to five days after the child has been exposed to the germs. SIGNS AND SYMPTOMS Impetigo typically appears as fragile blisters containing thin, yellow pus. The initial sore often occurs at a point where the skin has been injured or irritated by an insect bite, a scrape, or a skin condition. If the child picks at the nose, the blister may appear in that area. The blister breaks easily, leaving an open, weeping sore that increases in size. The discharge hardens into a yellow crust or scab that looks like hardened honey. Impetigo spreads rapidly, and the child can aggravate this by scratching a sore and transferring the discharge on his hands to other parts of the body. The infecting bacteria can be identified only through laboratory tests. If the culprit is the streptococcus bacterium, the doctor will watch for the possible development of a kidney condition known as glomerulonephritis. HOME CARE If only a few small areas are involved, scrub the crusts of the sores with soap and water. (Streptococcal and staphylococcal infections thrive under the crusts.) Apply a nonprescription antibiotic ointment several times a day. Cover the sores with gauze to keep the ointment in place and to discourage the child from scratching and spreading the disease. PRECAUTIONS - To prevent impetigo, wash minor scratches and scrapes with soap and water and cover with a sterile bandage. - Impetigo is highly contagious. If your child has impetigo, watch the rest of the family carefully for signs of the disease and treat cases promptly if they occur. - Keep the washcloth, towel, and clothing used by the child separate from items used by other family members. This will reduce the chance that the disease will spread. - Launder the infected child's clothing and linens frequently. Ordinary laundering sterilizes adequately. - If home treatment for impetigo is effective, do not discontinue the treatment until the sores have completely healed and the skin is smooth. It can take a long time to clear the condition completely. - If home treatment does not seem to be working within four or five days or if the sores continue to spread or multiply, see your doctor. MEDICAL TREATMENT The doctor may culture the sores to identify the causative organism. If streptococcal infection is present, a ten- to 14-day course of penicillin may be prescribed. If staphylococcal infection is found, further tests may be required to determine the most effective antibiotic medication.
