Web MD states that ringworm is indeed contagious. Ringworm can be spread by skin-to-skin contact or simply by sharing personal items such as towels, clothing, or sports equipment..
Web MD explains that ringworm is a fungus that lives in the superficial layer of skin, and it is expressed in the form of tiny blisters or scaly skin in the shape of rings. Ringworm can be successfully treated at home in most cases with over-the-counter antifungal ointments. However, lesions that do not clear within two weeks of using the antifungal ointment should be treated by a physician who can provide a more aggressive approach.
