What should you know about infant ringworm?

Ringworm can form a round or oval patch with a more active scaly edge and clearer-looking skin toward the centre, though infants may not show a classic ring. It can itch and may enlarge gradually. Infection may spread through close contact, shared towels, clothing, bedding, pets, or surfaces. A facial or scalp rash can resemble eczema or another infection, so a [Skin Rash](/symptoms/skin-rash/) or [Scaly Skin](/symptoms/skin-scaling/) page cannot replace examination. The condition page for [Ringworm](/conditions/ringworm/) provides broader context.

Arrange a clinician’s assessment rather than relying on appearance alone. Wash hands after touching the area, keep the patch covered with loose clothing when practical, and do not share towels, hats, brushes, clothing, or bedding. Wash these items regularly and avoid scratching or picking. Ask a clinician to check household members and pets if there is a possible shared source. Do not use a combination cream or an oral medicine without advice, because the correct treatment depends on the body site and extent.

Seek prompt medical review if the rash involves the scalp, hair, eyelids, or a large area, or if it is painful, swollen, wet, crusted, rapidly spreading, or associated with fever or poor feeding. Contact the clinician again if the rash worsens, new patches appear, or treatment causes a marked reaction. A scalp infection may require a different approach from a small patch on the body.

Ask whether the appearance and body site fit ringworm, whether testing is needed, whether [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) or [Oral Antifungal Treatment](/treatments/medical-dermatology/oral-antifungal-therapy/) is appropriate, and how to protect siblings and caregivers. Mention contact with pets, recent travel, shared items, and any products already applied.
