The fungi that cause athlete's foot can spread from body part to body part, like from your foot to your toenail, or from your foot to your groin. These fungi can also spread from person to person. To prevent the spread of athlete's foot, you can do the following:
• Treat your infected skin with antifungal medication
• Wash your hands after touching the affected area until your infection clears completely
• Keep your feet clean and dry (because fungi thrive in warm, moist environments)
• Wear cotton socks and "breathable" footwear
• Avoid reusing or sharing towels, shoes, socks, and other items that could carry infected skin
