Overview

Impetigo (say "im-puh-TY-go") is a skin infection caused by bacteria. It causes blisters that break open, ooze fluid, and form patches of crusty sores. These patches may look yellow, gold, or brown.

Impetigo can be anywhere on the body. Scratching the sores may spread the infection to other parts of the body. It can also spread to others through close contact or by sharing towels, clothing, and other items.

Prescription antibiotic ointment or pills can usually cure impetigo.

How can you care for your child at home?

• Apply antibiotic ointment exactly as instructed.
• If the doctor prescribed antibiotic pills or liquid for your child, give them as directed. Do not stop using them just because your child feels better. Your child needs to take the full course of antibiotics.
• Gently wash the sores with clean water each day. If crusts form, your child's doctor may advise you to soften or remove the crusts. Do this by soaking them in warm water and patting them dry. This can help the cream or ointment work better.
• After you touch the area, wash your hands with soap and water. Or you can use an alcohol-based hand sanitizer.
• Trim your child's fingernails short to reduce scratching. Scratching can spread the infection.
• Do not let your child share towels, sheets, or clothes with family members or other kids at school until the infection is gone.
• Wash anything that may have touched the infected area.
• A child can usually return to school or daycare after 24 hours of treatment.
