Factors that can increase risk of nail fungus

Nail fungus (also called "Onychomycosis") is a common infection of the nail. It begins as a white or yellow-brown spot under the tip of your fingernail or toenail. As the fungal infection goes deeper, the nail may discolor, thicken and crumble at the edge. Nail fungus can affect several nails.

灰指甲（也称为“甲真菌病”）是一种常见的指甲感染。 它开始时是指甲或脚趾甲尖下的白色或黄棕色斑点。 随着真菌感染的深入，指甲可能会变色、变厚并在边缘碎裂。 灰指甲会影响多个指甲。
