What should you know about medical name for ringworm?

Ringworm is not caused by a worm. Dermatophyte fungi use keratin in the outer layer of skin, hair, or nails. On the body, the rash may form an expanding ring with a more active, scaly edge and clearer skin toward the centre, but appearances can vary. It can spread through close skin contact or shared towels, clothing, sports equipment, and other personal items. Moisture and friction can help fungi persist.

Keep the affected area clean and dry, wash hands after touching it, and avoid sharing towels or clothing. Wash garments and bedding regularly and let them dry thoroughly. A clinician or pharmacist may recommend Topical Antifungal Treatment for limited skin infection. Infection involving the scalp, nails, extensive areas, or skin that has not improved may need Oral Antifungal Treatment and a confirmed diagnosis.

Arrange care when a rash is spreading, painful, oozing, recurrent, or difficult to identify, or when it affects the scalp, beard area, or nails. Seek advice sooner for a child, a person with reduced immunity, or a rash that worsens after steroid cream. A Skin Rash with persistent scaling has causes beyond fungal infection and may need examination.

Does this look like tinea corporis or another rash? Should I use a topical medicine, and for how long? Does anyone in my household or sports group need checking?
