What should you know about dead ringworm?

Ringworm is a fungal infection, not a worm. As inflammation settles, a patch may become less red, flatter, dry, or scaly. Residual discolouration can remain after the infection improves, so appearance alone cannot confirm that the fungus has cleared.

An active patch may still expand, itch, form a ring-like edge, or show scaling. A [Skin Rash](/symptoms/skin-rash/) or [Scaly Skin](/symptoms/skin-scaling/) page can help describe symptoms, but diagnosis may require a clinician’s examination, especially when the rash is on the face, scalp, nails, or a child.

Use the prescribed or pharmacist-recommended antifungal exactly as labelled and for the advised duration, even if the patch looks calmer. Keep the area clean and dry, wash hands after applying medicine, and do not share towels, clothing, hairbrushes, or sports equipment. Wash fabrics that touch the affected area regularly.

Avoid steroid cream on a suspected fungal rash unless a clinician specifically recommends it; steroids can alter the appearance and allow infection to spread. Depending on site and extent, care may involve [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) or [Oral Antifungal Treatment](/treatments/medical-dermatology/oral-antifungal-therapy/).

Arrange medical review if the patch continues to enlarge, new areas appear, treatment irritates the skin, or there is no clear improvement after the advised course. Seek prompt care for marked pain, pus, fever, facial swelling, or involvement of the eyes. Scalp or nail infection needs assessment because it may require treatment by mouth.

Does this look like active ringworm or post-inflammatory scaling? Which treatment suits the body site? How long should I use it, and should household contacts or pets be checked if infection keeps returning?
