Causes of Ringworm
Ringworm is a common skin disorder, especially among children, but it may affect people of all ages. The agents are called the dermatophytes, which means skin fungi. They rarely invade deeper into the body and cannot live on mucous membranes, such as those in the mouth or vagina.
Ringworm spreads from person to person by touch. When someone with ringworm touches or scratches the rash, the fungus sticks to the fingers or gets under the fingernails. The fungus is then spread when that person touches someone else.
Ringworm of the scalp can also spread if combs and hairbrushes are shared.
These infections are caused by several types of mold-like fungi called dermatophytes that live on the dead tissues of the skin, hair, and nails.

Diagnosis of Ringworm Ringworm is diagnosed primarily based on the appearance of the skin.
A KOH test is used to diagnose fungal infections of the skin or nails. The skin or nail is scraped with a scalpel or glass slide causing dead skin cells to fall off onto a glass slide. A few drops of Potassium hydroxide (KOH) are added to the slide and the slide is heated for a short time. The KOH dissolves the material binding the skin cells together releasing the fungus.
Diagnosis can be made by scraping the affected area of skin and examining the cells under a microscope.
Fungus may appear florescent when your skin is examined with a blue light in a dark room.
Skin scrapings for microscopic examination and a culture of the affected skin can establish the diagnosis of tinea or rule it out.
