Ringworm on a cat's nose

Ringworm is a fungus that can affect animals and people. A cat's nose may show scaling, crusting, hair loss or irritation, but these signs can have other causes. A person exposed to an infected animal may later develop an itchy, expanding [Skin Rash](/symptoms/skin-rash/) or [Scaly Skin](/symptoms/skin-scaling/). Human symptoms do not prove the cat was the source.

Children, people with reduced immunity and those handling the animal closely may need particular care. A veterinarian should diagnose and treat the cat; do not apply human medicines to the animal unless advised.

Avoid kissing the cat or touching its nose, wear gloves for necessary handling, wash hands with soap and clean surfaces the cat uses. Arrange veterinary care and follow cleaning instructions. If a human patch appears, do not share towels or clothing and ask a clinician about [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/). More extensive infection may require [Oral Antifungal Treatment](/treatments/medical-dermatology/oral-antifungal-therapy/).

Seek medical advice for a growing, scaly or itchy patch after animal contact, especially on the face or scalp. Prompt care is appropriate for eye involvement, pus, significant pain, fever, widespread lesions or symptoms in someone with reduced immunity. Seek veterinary care for the cat's nose changes rather than waiting for them to resolve.

Could this rash be ringworm or another exposure-related condition? Should household contacts be checked? Which treatment is suitable for this location, and how should we coordinate care with the veterinarian?
