Athlete's foot is easily spread (contagious)-you can get it by touching the affected area of a person who has it. More commonly, you pick up the fungi from damp surfaces, such as the floors in public showers or locker rooms.

Although athlete's foot is contagious, some people are more likely to get it (susceptible) than others. Susceptibility may increase with age. Experts don't know why some people are more likely to get it. After you have had athlete's foot, you are more likely to get it again.

If you aren't susceptible to athlete's foot, you may come in contact with the fungi that cause athlete's foot yet not get an infection. However, you can still spread the fungi to others.
