What harm does onychomycosis have to the human body

The harm of onychomycosis to human body is mainly manifested in three aspects: the first aspect is direct damage to nails, severe damage to the nail deck, nail deformation, soft and brittle, thickening, and pain caused by extrusion when walking. The second aspect affects the appearance due to damage to the nail deck. The third aspect is due to damage to the barrier function caused by fungi affecting the skin around the nail. It is easy to cause onychia or erysipelas due to secondary bacterial infection. In addition, onychomycosis can also cause transmission in families and collectives, endangering others, so it should be treated early.
