Care Advice

What You Should Know About Impetigo:

• Impetigo is a skin infection. Most often, it starts in a scratch or insect bite.
• It usually responds to treatment with any antibiotic ointment.
• Here is some care advice that should help.

Remove Scabs:

• Soak off the scab using soap and warm water. The bacteria live underneath the scab.

Antibiotic Ointment:

• Put an antibiotic ointment (such as Polysporin) on the sores. No prescription is needed. You can also use one you already have.
• Do this 3 times per day.
• Cover it with a bandage to prevent scratching and spread.
• Repeat the washing, ointment and dressing 3 times per day.

Do Not Pick at the Sores:

• Help your child not to scratch and pick at the sores. This spreads the impetigo.

Return to School:

• Impetigo is spread to others by contact with skin lesions.
• Wash the hands often. Try not to touch the sores.
• For mild impetigo (1 or 2 sores), can go to school if it is covered.
• For severe impetigo, child needs to take an oral antibiotic for more than 24 hours. Then your child can go back to school.
• Contact Sports. In general, needs to be on antibiotics for 3 days before returning to sports. There must be no pus or drainage. Check with the team's trainer if there is one.

What to Expect:

• The skin is healed in 1 week.
