Impetigo

What is impetigo?

Impetigo is a skin infection caused by bacteria. The infection can cause sores to form anywhere on your body. The sores develop watery or pus-filled blisters that break and form thick crusts. Impetigo is most common in children and spreads easily from person to person.

How is impetigo treated?

Impetigo is treated with antibiotics. Your caregiver may order antibiotic pills, or a cream to put on your skin. Wash your skin and gently remove any crusts before you apply the antibiotic cream.

How do I prevent the spread of impetigo?

  • Avoid direct contact: You can spread impetigo if someone touches or uses something that touched your infected skin. You can also spread impetigo on your own body when you touch the area and then touch somewhere else. Keep the sores covered with gauze so you will not scratch or touch them. Keep your fingernails short. Your child may need to wear mittens so he does not scratch his sores.

  • Wash your hands: Always wash your hands after you touch the infected area. Wash your hands before you touch food, your eyes, or other people. If no water is available, use an alcohol-based gel to clean your hands. Wash your hands again with soap and water as soon as possible.

  • Wash household items: Do not share or reuse items that have come in contact with impetigo sores. Examples include bedding, towels, washcloths, and eating utensils. These items may be used again after they have been washed in hot water and soap.

How do I clean my sores safely?

Wash your skin sores with antibacterial soap and water. You may need to do this 2 to 3 times each day until the sores heal. If the area is crusted, soak it in warm, soapy water before you wash. Gently wash the sores with gauze or a clean washcloth to remove the crust. Pat the area dry with a clean towel. Wash your hands, the washcloth, and the towel after you clean the area around the sores.

When is it safe to return to work or school?

You may return to work or school 48 hours after you start the antibiotic medicine. If your child has impetigo, tell his school or daycare center about the infection.

When should I contact my caregiver?

Contact your caregiver if:

  • You have a fever.

  • The sores become more red, swollen, warm, or tender.

  • The sores do not start to heal after 3 days of treatment.

  • You have questions or concerns about your condition or care.

When should I seek immediate care?

Seek care immediately or call 911 if:

  • You have painful, red, warm skin around the blisters.

  • Your face is swollen.

  • You urinate less than usual or there is blood in your urine.
