How to help prevent impetigo

Impetigo is a contagious bacterial infection that can enter through a scratch, insect bite, cut, or irritated patch of skin. It often produces small blisters or sores that break and develop a yellow-brown crust. Atopic Dermatitis can increase opportunities for bacteria to enter when itching leads to scratching. Crusting Skin is not always impetigo, so a clinician may need to inspect the area.

Wash hands after touching a sore and keep fingernails short to reduce skin injury from scratching. Clean affected skin gently, pat it dry, and cover it with a clean dressing when practical. Do not share towels, face cloths, razors, clothing, or bedding; wash these items regularly and avoid picking at crusts. Do not apply leftover antibiotics. A clinician may prescribe Topical Antibiotic Therapy for limited infection or Antibiotics For Skin Infection when broader treatment is needed. Follow the prescribed course exactly.

Arrange medical assessment for spreading sores, increasing pain, fever, facial involvement, eye-area lesions, or infection in a young child. Seek prompt care if the skin becomes hot and swollen or if someone in the household has a weakened immune system. Keep the area covered and avoid close skin contact until a clinician advises that normal activities are appropriate.

Does this crust look like impetigo or another skin problem? Which treatment is suitable for the number and location of sores? How should I manage an itchy underlying condition, and when can school, sport, or work resume?
