What should you know about equine ringworm?

Despite its name, ringworm is not caused by a worm. Fungi can live on an infected horse’s coat, tack, grooming tools, blankets and stable surfaces. A person may develop an expanding, ring-shaped or irregular rash with scaling, redness or itch after contact. The appearance can vary, so a clinician may need to examine the skin and sometimes test a sample before choosing treatment. Avoid sharing towels, clothing or grooming items while the rash is being assessed.

Wash hands and exposed skin after handling the horse or its equipment, launder washable fabrics, and clean items that may carry fungal material. Keep the affected area dry and avoid scratching, which can damage the skin and spread irritation. Arrange medical advice if a new rash follows animal contact, especially if it is spreading or does not settle. Treatment may involve a [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/); extensive or difficult infections may need [Oral Antifungal Treatment](/treatments/medical-dermatology/oral-antifungal-therapy/).

Seek prompt care for rapidly worsening redness, marked swelling, pus, fever, severe pain, involvement around the eyes, or a rash in a baby or someone with reduced immunity. These features can signal a complication or a different skin problem. For background, see [Ringworm](/conditions/ringworm/), [Skin Rash](/symptoms/skin-rash/), or [Scaly Skin](/symptoms/skin-scaling/).

Could this be fungal, and would a skin scraping help confirm it? Should household or stable contacts be checked? Which treatment suits the location and extent of the rash, and how should I clean clothing or equipment?
