Health Care Guide

Impetigo is a bacterial infection that is much more common in children than in adults. It often starts when a small cut or scratch becomes infected. Symptoms are oozing, honey-coloured, crusty sores that often appear on the face between the upper lip and nose, especially after a cold. Scratching the sores may spread impetigo to other parts of the body.

Prevention

Wash all scratches and sores with soap and water.
If your child has a runny nose, keep the area between the child's upper lip and nose clean to prevent infection.
Keep your child's fingernails short and clean.

Home Treatment

Small areas of impetigo may respond well to prompt Home Treatment.

Remove crusts by soaking the area in warm water (use a warm washcloth for the face) for 15 to 20 minutes; then scrub gently with a washcloth and antibacterial soap. Pat dry gently; do not rub. Repeat several times a day.
Apply an antibiotic ointment. Cover the area with gauze taped well away from the sores. This will help keep the infection from spreading and prevent scratching.
Adult men with impetigo should shave around the sores, not over them, and use a clean blade daily. Do not use a shaving brush.
To prevent spreading the infection, do not share towels, washcloths, or bath water.
