Nail fungus is a common type of fungal infections of nails, contributing towards almost 50% of the nail abnormalities. Fungal Nail Infection

Nail fungus, medically known as onychomycosis is an infection caused due to fungus, affecting mostly toenail or thumbnail, but can spread to other nails as well. The infection may initiate as a white or yellow spot under the tip of the nail and can infect other nails. With the progression of the fungus, the nail may get thickened, discolored and/or crumbled.

Fungal infections of nails are usually caused by Candida, yeast and molds. The entry of this pathogenic fungus is generally through the tiny skin cuts, bruises between the finger beds.
