What should you know about equine ringworm stages?

After contact with an infected horse or contaminated material, the first change may be mild itch, redness or a small rough area. Over time, the edge can become more noticeable, with scaling or clearer skin toward the centre. Lesions can join or appear on more than one body area, particularly when scratching or repeated exposure moves fungal material. The pattern is not a reliable way to date an infection, and eczema, irritation and other rashes can look similar.

At the first suspicious change, stop sharing towels and clothing and wash skin after handling horses, tack or grooming tools. Photographing the area can help show change, but do not delay an examination if it is spreading. A clinician can decide whether [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) is appropriate; widespread, recurrent or hard-to-treat disease may require [Oral Antifungal Treatment](/treatments/medical-dermatology/oral-antifungal-therapy/). Follow the full plan even when itch improves.

Get prompt medical help for eye involvement, facial swelling, pus, severe tenderness, fever, fast expansion, or a rash affecting an infant or a person with impaired immunity. Seek advice if the area continues to enlarge despite treatment or if new patches keep appearing. [Ringworm](/conditions/ringworm/) and related descriptions such as [Skin Rash](/symptoms/skin-rash/) and [Scaly Skin](/symptoms/skin-scaling/) provide useful context.

Does the appearance fit ringworm or another rash? Should testing be done before treatment? How long should I use the medicine, and what cleaning steps reduce re-exposure from the horse or equipment?
