How Do You Contract Foot Fungus My Mom Has Toenail Fungus?

My mom has toenail fungus? - how do you contract foot fungus

My mother always wanted to let you know of a pedicure, if you know that I have to walk phobia (no, I do not just ask how the feet, I think they're gross) there is that, anyway. Well, now she always has something under the toenail, I think your fungus. I heard that toenail fungus is highly contagious and can even touch it with your hands (I know, I know, EW). I told my mother, but she does not believe that she thinks I just do not want to touch his feet, but I contract toenail fungus. How can I convince them that I am telling the truth about his toenail fungus?
