Toenail Fungus is contagious (also medically known as onychomycosis). A fungus is a living organism that can be transmitted from one person to another. It can be transmitted in places like pools, shower stalls, locker rooms, dirty floors and old shoes or by wearing someone else’s shoes that has the infection. The fungus also can be spread from one of your toenails to your another one of your toenails. It is possible for the infection to be spread from pedicures at nail salons as the fungus can be transmitted through nail polish and instruments that are not properly sterilized. The most common symptom of a fungal nail infection is the nail becoming thickened and discolored: white, black, yellow or green. Check for more nail fungus symptoms.
It is a responsibility to keep toenail fungus to yourself. Avoid public places and use protective footwear whenever possible. Wear socks around the house to reduce the risk of spreading it.
