Some of these include keeping the feet dry, clipping toenails short; using a separate nail clipper for infected toenails; using socks made from well-ventilated cotton or synthetic moisture wicking materials to soak moisture away from the skin to help keep it dry ; avoiding tight-fitting footwear, changing socks frequently; and wearing sandals while walking through communal areas such as gym showers and locker rooms.
Nails can house and spread the infection. There is an increased risk of infection with exposure to warm, moist environments e. Cleaning surfaces with a chlorine bleach solution prevents the disease from spreading from subsequent contact.
Cleaning bathtubs, showers, bathroom floors, sinks, and counters with bleach helps prevent the spread of the disease, including reinfection.
Keeping socks and shoes clean using bleach in the wash is one way to prevent fungi from taking hold and spreading. Avoiding the sharing of boots and shoes is another way to prevent transmission. Athlete's foot can be transmitted by sharing footwear with an infected person. Hand-me-downs and purchasing used shoes are other forms of shoe-sharing. Not sharing also applies to towels, because, though less common, fungi can be passed along on towels, especially damp ones.
Because the outer skin layers are damaged and susceptible to reinfection, topical treatment generally continues until all layers of the skin are replaced, about 2—6 weeks after symptoms disappear.
Keeping feet dry and practicing good hygiene as described in the above section on prevention is crucial for killing the fungus and preventing reinfection. Treating the feet is not always enough. Once socks or shoes are infested with fungi, wearing them again can reinfect or further infect the feet.
