Reinfection, incomplete treatment, and the presence of susceptibility factors in the host are all reasons for recurrent episodes of foot odor, or tinea pedis. Tinea pedis has a high recurrence rate. Reinfection is one of the reasons for its susceptibility to recurrence. Tinea pedis can recur when re-infected with superficial skin fungi such as Trichophyton rubrum, Trichophyton mustelii, and Tinea floccidum. Incomplete treatment can also lead to recurrence of tinea pedis. Treatment of tinea pedis takes a long time, usually at least 1 month, and stopping the medication as soon as the symptoms disappear and the course of treatment is insufficient can cause recurrence of tinea pedis. In addition, if the host has undiscovered and uncorrected susceptibility factors, such as diabetes mellitus, tumors, and immunodeficiency diseases, it can also lead to recurrent episodes of tinea pedis. Tinea pedis should consult a doctor in time, follow the doctor’s instructions to use medication in sufficient quantity and duration, pay attention to personal hygiene, change and wash shoes and socks in time, and keep the local area clean and dry, etc., which can help to prevent the recurrence of tinea pedis.
