Cat ringworm is contagious to humans. Feline ringworm is a common skin disease in cats caused by fungi. It is somewhat similar to human athlete's foot. The bacteria are very stubborn and difficult to treat. Among the five fungi that have been discovered so far that cause cat ringworm, Microsporum auduanensis is easily transmitted to humans directly through utensils, combs, scissors, cushions, etc. used by cats suffering from cat ringworm. After people are infected with cat ringworm, in mild cases, they will feel skin itching and rash, and in severe cases, hair loss and large-area skin lesions will occur.
