Ringworm

What is ringworm?

The term ringworm refers to fungal infections that occur on the surface of the skin. The name comes from a preconceived idea that the infection was caused by a worm, which it is not. This is a fungal infection of the skin. However, the name of the ringworm remains. Some of these fungi produce round scaly patches on the skin, but most do not.

On the other hand, very round red spots or rashes on the skin are not caused by a fungal infection. Physical examination of the affected skin, evaluation of skin scraping under a microscope, and culture tests can help healthcare professionals make proper diagnoses and distinctions of other conditions. Proper diagnosis is the best for successful treatment.

The medical term for ringworm (tinea is the Latin name for a growing worm.) Medical professionals add another term to refer to the part of the body that contains the fungus. For example, tinea capitis refers to ringworm of the scalp, body fungus of tinea corporis, foot fungus tinea pedis, etc.
