YES! Toenail fungus is contagious, in fact if you have toenail fungus, chances are you got it from someone else! This fungus spreads most in moist, dark warm areas such as showers, pools, gyms, locker rooms, through socks and shoes.
Preventative measures for preventing spreading or getting toenail fungus include not sharing shoes/socks, wearing water shoes at public places like the gym and to discontinue pedicures. In addition, you will need to see a doctor to rid yourself of the fungus. We have seen people that have had toenail fungus for nearly 20 years....believe us, it's not going away by itself.
