Athlete's foot is a disease caused by fungal infection. Fungal infections are highly contagious and recurrent, but they can be completely cured with proper treatment. It is recommended to visit the dermatology department of a regular hospital and apply antifungal cream. The treatment should be prolonged, lasting at least one to two months or more, so that the deep-seated fungus can be completely killed and eradicated. After the treatment, regulate your diet and lifestyle habits; avoid contact with small animals, dirty water, sand, etc., try to avoid spicy and irritating foods, and do not stay up late. If family members also have this disease, they must be treated at the same time, and towels, bath scrubbers, or foot wiping towels should not be shared.
