Q: What is ringworm?

A: Ringworm is in fact not caused by a worm but instead by a fungus that infects the roots of hairs. The hairs of the horse will generally fall out in tufts producing small bare patches, which are commonly circular in shape (hence the name ‘ringworm’). The horse may have one or two bare patches, or multiple, depending on the severity and duration of infection. Ringworm is infectious to other horses and to people so the horse should be isolated to avoid physical contact with other horses, and the tack and grooming kit must be kept separate. Anyone who has contact with the horse must wash their hands immediately after dealing with the horse.

Ringworm will require your vet to provide an anti-fungal treatment, so contact them if you suspect your horse is suffering from ringworm.
