Healing impetigo scabs: what to know

Impetigo is a contagious bacterial infection of the surface of the skin. Small blisters or open sores can dry into a yellowish or brown crust. A crust suggests the sore is drying, but it does not by itself confirm that infection has cleared. New lesions, wetness, or crust appearing at nearby sites can mean the infection remains active. People with eczema, including [Atopic Dermatitis](/conditions/atopic-dermatitis/), may have more vulnerable skin.

Wash hands after touching the rash, clean gently with water, and avoid picking or scraping the crust. Keep the area covered with a clean dressing when practical, do not share towels or razors, and wash clothing and bedding regularly. A clinician may recommend [Topical Antibiotic Therapy](/treatments/medical-dermatology/topical-antibiotic-therapy/) for limited infection or [Antibiotics For Skin Infection](/treatments/medical-dermatology/antibiotic-therapy-for-skin-infection/) when a wider area is involved. Follow the prescribed course.

Contact a clinician if sores multiply, fail to improve, or affect the eyes, mouth, or a large area. Seek urgent advice for rapidly spreading redness, marked swelling, severe pain, fever, unusual drowsiness, or reduced drinking in a child. Keep children away from close contact until a clinician advises that the infection is no longer readily spread.

Do these scabs still look infectious? Is a cream or oral medicine more suitable? How should I clean and cover the sores? When can my child return to nursery or school?
