What does the term "onychomycosis" refer to?

Onychomycosis specifically refers to a fungal infection of the nails, making "nail fungus" the accurate definition. This condition is characterized by changes in the appearance of the nails, which may become discolored, thickened, or even brittle as the infection progresses. Understanding this term is important in the context of nail health, as it can affect both the physical condition of the nails and the overall health of the individual if left untreated. The other terms, such as nail trauma, nail discoloration, and nail loss, describe different issues that do not specifically refer to a fungal infection, highlighting the distinct nature of onychomycosis.
