What should you know about crusted impetigo?

The rash often begins where skin has been scratched, irritated or affected by another itchy condition. Fluid from a blister or sore dries into a characteristic crust, and nearby spots may develop through touch or shared items. Atopic Dermatitis can create a damaged, itchy skin barrier that makes infection easier to introduce. Crusting Skin explains the visible symptom.

Arrange medical advice so the extent and treatment can be assessed. Keep sores clean and covered with a light dressing if advised, wash hands after touching the area, and avoid sharing towels, clothing or bedding. Keep fingernails short and discourage scratching. A clinician may recommend Topical Antibiotic Therapy for limited disease or Antibiotics For Skin Infection when wider treatment is needed; use only the prescribed course.

Seek prompt care if infection is spreading quickly, the skin is increasingly painful or warm, fever develops, or sores are near the eyes. Urgent assessment is needed for unusual drowsiness, severe illness, facial swelling or eye symptoms. Children, people with eczema and anyone with reduced immune protection may need earlier review.

Ask how long the infection may remain contagious, how to clean and cover it, whether close contacts need advice, and what improvement should look like after treatment begins.
