What should you know about ringworm spots?

The colour of a ringworm spot varies with skin tone. The border may feel raised, dry, or rough, while the middle can look less inflamed. One patch may occur alone or several may appear on nearby or separate areas. Itch can encourage rubbing, which makes the outline harder to recognise.

A circular shape is not enough to diagnose ringworm. Other causes of a [Skin Rash](/symptoms/skin-rash/) can look similar, and some fungal patches are not ring-shaped. A clinician may ask where the spot began, whether it is spreading, and whether there is [Scaly Skin](/symptoms/skin-scaling/).

Keep the spot dry and avoid scratching. Wash hands after applying any medicine, launder clothing and towels regularly, and do not share personal items. Check pets and household contacts through a professional if several people develop similar patches; animals can carry fungus without an obvious skin problem.

Use [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) only as directed for the suspected area. Do not use a mixed steroid product unless prescribed for this specific problem. A clinician may recommend [Oral Antifungal Treatment](/treatments/medical-dermatology/oral-antifungal-therapy/) when spots are widespread, persistent, or unsuitable for cream.

Seek assessment when a spot is spreading, painful, oozing, very inflamed, or failing to improve after directed treatment. Get prompt help for fever, rapidly spreading redness, or a rash near the eye. Children, people with reduced immune defences, and people with diabetes may benefit from earlier advice for a new spreading rash.

Ask what features support ringworm, whether testing is needed, how long to apply treatment, and whether household members or pets should be checked. Bring a list of products placed on the spot, including creams bought without a prescription.
