It is important to realize that ringworm is mainly caused by fungal infections in the feet, so it is important to emphasize antifungal infection treatment when ringworm occurs. It is important to keep the feet clean and dry when tinea pedis occurs, and to be careful not to scratch or massage the feet if they are itchy, as this may lead to the fungal infection of the feet becoming self-infected. Fungal infections of the foot can also be treated with drugs, including topical medications and oral antifungal drugs. Topical medications mainly include the application of ketoconazole or econazole creams for application, and internal medications are mainly antifungal medications applied, such as itraconazole, for treatment, and antifungal treatment must be adhered to for more than 2-4 weeks; if the time and efficacy are not enough, these foot infections will be difficult to completely eradicate and will easily recur.
