Is ringworm a fungal infection?

Ringworm is a skin infection that is caused by a fungi known as dermatophytes, according to MedicineNet. There are several types of common dermatophytes that can result in ringworm, including Trichophyton rubrum, Trichophyton tonsurans and Trichophyton interdigitale.

The main symptom of ringworm is a circular, itchy rash on the skin, states the Centers for Disease Control and Prevention. It's a highly contagious condition that can be easily passed between animals as well as humans through casual contact.

Because dermatophytes require moisture and heat in order to thrive, patches of ringworm are frequently found in the folds of the skin. Fungal infections are often transmitted through contaminated surfaces at communal locker rooms and public swimming pools, reports MedicineNet. The fungus can also be transmitted through fabric items such as clothing and bedding. Several different types of ringworm exist, and treatment options include both over-the-counter and prescription anti-fungal treatments.
