Nail fungal infections are also called onychomycosis. It becomes more common as a person gets older. It rarely affects children and is more prevalent among men. This type of infection can cause the nail to discolor, become distorted in shape, and easy to crack or break. It affects the toenails more than the fingernails.
6What is the cause of toenail fungal infections?
Nail fungal infections are caused by the overgrowth of fungi in, on, and underneath one’s nail. Fungi thrive easily in a warm and damp environment. This is the type of environment that causes fungi to overpopulate. The fungi that cause nail fungus infections are the same fungi that bring us jock itch, ringworm, and athlete’s foot. You may contract the infection from someone who has it or through contact with any surface that has been infected with the fungus.
