Athlete's foot is a disease caused by fungal infections and is not related to a lack of vitamins. However, supplementing with vitamins appropriately during treatment can be helpful. This disease is highly contagious and recurrent, and once identified, it must be treated formally. It is recommended to visit a dermatologist at a reputable hospital for confirmation before treatment. Antifungal creams can be applied topically twice a day, and the treatment should be maintained for at least one to two months to completely kill the deep-seated fungi and prevent recurrence of the condition. It is advisable to avoid keeping small animals at home, avoid contact with dirty water and soil, and refrain from using public baths and swimming pools. Bath towels and washcloths should be used separately from those of other family members.
