What should you know about udder impetigo?

Impetigo may begin where skin is scratched, irritated, or already inflamed. Small blisters or shallow sores can break and form sticky yellow crusts. The affected area may itch, sting, or feel tender. Atopic dermatitis can weaken the skin barrier and make infection easier to develop. Crusting skin around the nipple or udder also has other possible causes, so appearance alone cannot confirm the diagnosis.

Wash hands before and after touching the area, keep the skin gently clean and dry, and avoid picking or sharing towels, clothing, or breast pumps. Cover draining lesions with a clean dressing when practical. A clinician may prescribe Topical Antibiotic Therapy for limited disease or Antibiotics For Skin Infection when lesions are extensive, recurrent, or accompanied by wider inflammation. Do not apply leftover medicine without advice.

Seek same-day medical advice for fever, rapidly spreading redness, increasing warmth, severe pain, pus, swollen glands, or illness in an infant who may have contact with the lesion. Ask specifically about safe feeding, pumping, and cleaning instructions if the affected skin is near the nipple. Urgent care is appropriate for marked weakness or rapidly worsening swelling.

Does this look like impetigo or another nipple and skin-fold condition? Is a swab needed, which treatment is suitable, and how should I protect a baby or household contacts from spread?
