What should you know about rabbit ringworm?

The name is misleading: ringworm is caused by fungi, not a worm. A rabbit may carry the fungus on its skin or fur, sometimes with obvious bare patches and sometimes without clear signs. People can develop a spreading patch, scaling, irritation or broken skin where the fungus has taken hold. The rash may appear days after exposure, so the source is not always obvious. See Ringworm for a broader overview, and learn about Skin Rash or Scaly Skin if the appearance is unclear.

Arrange an assessment if a new rash follows handling a rabbit, cleaning its enclosure or touching shared bedding. Avoid sharing towels, clothing or grooming tools, wash hands after contact and clean surfaces that may carry loose hairs or skin flakes. Do not apply steroid cream alone to a suspected fungal rash because it can alter its appearance and allow it to spread. A clinician may recommend Topical Antifungal Treatment; more extensive or persistent infection may need Oral Antifungal Treatment. The rabbit and other household animals should be assessed by a veterinarian.

Seek prompt medical advice for a rapidly expanding rash, marked pain, pus, fever, involvement of the scalp or face, or a rash in a young child or person with reduced immunity. Seek urgent help for facial swelling, breathing difficulty or a severe allergic reaction. Arrange review when treatment is not helping or when new patches continue to appear, as another condition can look similar.

Could this be ringworm or another rash? Does the rabbit need veterinary testing? Should I use a topical medicine, and for how long? Do household members or pets need assessment? Which cleaning steps are necessary?
