Hi,thank you for posting your query on health care magic. I can understand your concern. Impetigo is a bacterial skin infection. Impetigo is contagious and can be spread to others through close contact or by sharing towels, sheets, clothing, toys, or other items. Impetigo is treated with antibiotics. For cases of mild impetigo, an antibiotic ointment or cream will be needed to apply on the sores. For cases of more serious impetigo,Oral Antibiotics may be needed. Gently wash the sores with clean water each day. If crusts form, try to soften the crusts by soaking them in warm water and then removing the crusts. This can help the cream or ointment work better. After you touch the area, wash your hands with soap and water or use an alcohol-based hand sanitizer. Try not to scratch the sores, because scratching can spread the infection to other parts of the body. You can help prevent scratching by keeping your child s fingernails short. You can cover the sores with a loose bandage. The sores need air to heal. Hope this answers your question.Get well soon to your son.
