What is the term for a fungal infection of the nail?

The term for a fungal infection of the nail is onychomycosis. This condition specifically refers to any nail infection that is caused by a fungus, typically resulting in nail discoloration, thickening, and sometimes even separation from the nail bed. Fungi thrive in warm, moist environments, which makes the nails susceptible to such infections, particularly in cases where there is damage to the skin or nails.

In contrast, paronychia refers to an infection of the skin surrounding the nail rather than the nail itself. Onychorrhexis describes brittle nails with longitudinal ridges or splits and is not linked to fungal infections. Onychosis is a general term for any nail disease or deformity, which may or may not include fungal infections. Understanding these specific definitions is crucial in the field of nail technology, as it helps in diagnosing and treating conditions appropriately.
