How common is skin rash in ringworm?

Ringworm is a fungal infection, not a worm. On the body, it may create a round or oval patch that expands outward, with scaling, itch, and a clearer centre. It can affect the feet, groin, scalp, nails, or other skin depending on the type. Other rashes can also be circular or scaly, so visual appearance cannot confirm ringworm without considering the site and history.

Keep the area clean and dry, wash hands after touching it, and avoid sharing towels, clothing, hairbrushes, or sports equipment. Change damp clothing and wash fabrics that contact the rash. Avoid steroid cream on an undiagnosed rash unless a clinician advises it, because steroids can alter the appearance of a fungal infection. A pharmacist or clinician can guide treatment based on the affected body site.

Get medical advice if the scalp, beard area, nails, or a large area is involved, or if the rash is painful, oozing, rapidly spreading, or not improving with suitable treatment. Children, people with reduced immunity, and anyone with repeated infections may need an examination. Seek urgent help for facial swelling, breathing difficulty, or severe illness.

Ask whether the site and border look fungal, whether testing is needed, how long to use the recommended treatment, and how to check household or sports contacts without sharing medication.
