Overview
Ringworm is a common fungal infection of the skin, scalp, or nails caused by dermatophyte fungi. Despite its name, it is not caused by a worm but by fungi that thrive on keratinized tissues. In Korea, dermatologists diagnose and treat ringworm effectively using antifungal medications and hygiene education to prevent spread and recurrence.
What is Ringworm?
Ringworm (also called tinea) is a contagious fungal infection that affects the outer layers of the skin, hair, or nails. It causes circular, red, scaly patches that may be itchy or inflamed. Different types of ringworm are classified based on the body part affected, such as tinea corporis (body), tinea capitis (scalp), and tinea pedis (feet).
