Impetigo

What is Impetigo?
Impetigo is a bacterial infection that is much more common in children than adults. Normal bacteria that are present on our skin, called "flora" enter an area on our skin that is already "damaged" and cause an infection. Impetigo has a special preference for skin that has already been injured by other skin problems such as eczema, poison ivy, insect bites, or areas where dermatitis is present (a skin sensitivity to soap or makeup).

What do I look for?
Impetigo presents itself in one of two ways, depending on which type of bacteria is causing the infection. 1) One type may begin as tiny blisters that eventually burst to reveal small wet patches of red skin that may weep fluid. Then a "honey-colored" crust covers the affected area. 2) The other type of impetigo begins as large blisters containing fluid that is first clear, and then becomes cloudy. These blisters are more likely to stay intact on the skin without bursting.

How do I treat Impetigo?

Small areas of Impetigo can be managed at home.
Remove the crusts by soaking the area in warm soapy water (use warm washcloth for the face) for 15-20 minutes. This is important, since the bacteria that are causing the infection live underneath the scab.
Then gently cleanse the area with an antibacterial soap such as Hibiclens or Betadine.
Gently pat dry - DO NOT RUB!
Apply an antibiotic ointment such as Bacitracin or Neosporin to the area and cover with a gauze bandage or Band-Aid. This will prevent the infection from spreading and help prevent scratching.

How do I prevent Impetigo from spreading?
Children are able to spread Impetigo from one area of their body to another when they scratch infected areas and touch another part of themselves. Impetigo can be spread to other family members on clothing, towels, and bed sheets that have been touched by the person's infected skin. It can also be spread among classmates and friends who come in to contact with infected skin. Make sure your child's fingernails are kept short and clean and that infected areas are always covered with a bandage. Do not share towels or clothes with other family members until the infection has healed. Separate the child's linens from other family members and wash them in very hot water.
