What type of disease causes marks ringworm?

Ringworm, also known as tinea corporis, is a common fungal infection of the skin. It is caused by a type of fungus called dermatophyte, which thrives on keratin, a protein found in the outermost layer of the skin, hair, and nails. Ringworm can affect different areas of the body, including the scalp (tinea capitis), body (tinea corporis), feet (tinea pedis, commonly known as athlete's foot), groin area (tinea cruris, or jock itch), and nails (tinea unguium).

Ringworm is contagious and can spread through direct contact with an infected person or animal, or by touching contaminated objects or surfaces. It can also be spread through sharing personal items such as towels, clothing, or combs.

Symptoms of ringworm typically include red, itchy, scaly patches on the skin that may have a raised, circular border. The patches may start small and gradually enlarge over time. In some cases, ringworm can also cause hair loss or nail infections.

Treatment for ringworm usually involves antifungal medications, which can be applied topically to the skin or taken orally. In severe cases, oral antifungal medications may be necessary. Proper hygiene, including washing the affected area regularly and avoiding contact with infected people or animals, is also important to prevent the spread of the infection.
