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. You can also spread it to others through close contact or when you share towels, clothing, and other items.

Prescription antibiotic ointment or pills can usually cure impetigo.

How can you care for yourself at home?

• Apply antibiotic ointment exactly as instructed.
• If your doctor prescribed antibiotic pills, take them as directed. Do not stop using them just because you feel better. You need to take the full course of antibiotics.
• Gently wash the sores with clean water each day. If crusts form, your doctor may advise you to soften or remove the crusts. You can 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.
• Don't share items such as towels, sheets, and clothing until the infection is gone.
• Wash anything that may have touched the infected area.
• Try to avoid scratching the area.
