Ringworm is a superficial skin infection, also known as tinea. It is caused by fungi call dermatophytes.
Fungi are microscopic plants that can live off dead tissues of skin, hair, and nails.
It is much like mushrooms and how they are able to grow on dead bark of a tree. Ringworm is characterized by a red ring of small blisters, or a red ring of scaly skin that will grow outward as the infection worsens. Children are most susceptible to catching ringworm, but adults are affected as well. Other forms of tinea that are more common in adults are athlete s foot, and jock itch. Once fungus is established, it spreads out in rings.
