What should you know about primary impetigo?

Primary impetigo is a contagious bacterial skin infection that often causes small sores, blisters, and yellow-brown crusts. It can begin on skin that was previously healthy and may spread through scratching, close contact, or shared towels and clothing.

The infection usually affects the outer layers of skin. A spot may start as a red, itchy area, then become a blister or shallow sore that leaks fluid and forms a crust. Face, hands and exposed skin are common sites, although other areas can be involved. Crusting skin can have other causes, so an examination helps confirm the diagnosis. Existing eczema, including Atopic Dermatitis, can make the skin easier to infect.

Arrange a medical assessment, especially if sores are spreading or affecting a child. Treatment may involve an Antibiotics For Skin Infection plan or Topical Antibiotic Therapy, depending on the number, location and depth of sores. Gently wash the area, pat it dry, keep nails short, and avoid picking. Do not share towels, bedding, razors or clothing; wash used fabrics and cover sores when practical.

Seek prompt care if redness, warmth, swelling or pain is extending, if pus collects, or if fever or marked tiredness develops. Urgent assessment is appropriate when the infection is near the eyes, the person seems very unwell, or sores are spreading quickly. Return for review if treatment does not improve the skin or new lesions continue to appear.

Ask which treatment is suitable for the affected area, how to clean and cover the sores, when close-contact activities can resume, and whether household members need advice. Mention eczema, allergies, recent antibiotics and any fever.
