Athlete's foot is a disease caused by fungal infection, with high infectivity and recurrence rates. Generally, the most common treatment is to directly apply antifungal ointment. With long-term treatment, it is usually completely curable. It is also beneficial to frequently wash the area with hot water to reduce the spread of the fungus locally. Additionally, washing with diluted salt water or water boiled with Sichuan peppercorns can inhibit and kill the fungus. After healing, prevention of recurrence is important. Avoid wearing flip-flops carelessly, steer clear of public baths and swimming pools, and do not share bathtubs or foot towels at home to prevent cross-infection.
