Without any treatment (one vet prescribed 6 weeks of oral antifungal + solution + shampoo, which other vets thought were extreme), based on my holistic vet's recommendation, the ringworm resolved itself quickly once his immune system was boosted (in our case, eliminating the food allergen and eating a good diet).
My vet told me that ringworm spores are everywhere and it's impossible to completely rid any environment of it, no matter how much you clean.
I did not quarantine or sanitize and my other pets did not get it and I personally believe it was because they had good immune systems.
I'm not implying anything medical-wise, just sharing my thoughts and experience with ringworm.
