Abstract

Epidemiological studies on tinea pedis and onychomycosis have been performed across Europe and East Asia. The prevalence of these conditions was 20%, respectively, and it increased with advancing age, more men than women had fungal infection of the feet. The prevalent predisposing factors were sports participation, average temperature, and family history of tinea pedis. The predisposing diseases were hypercholesterolemia, cardiovascular disease, diabetes mellitus, and osteoarticular disease. We conducted an epidemiological investigation to determine the prevalence and circumstances of untreated and unsuspected tinea pedis and onychomycosis. The results showed that the prevalence of occult athlete's foot was 25%, and that 59% of those cases were complicated by tinea unguium. The characteristics of patients with occult athlete's foot included a higher proportion of men and a tendency toward a low clinical score together with a high severity score. In the patient background, a strong correlation was observed between a positive KOH test result and characteristics such as past history of tinea pedis and/or onychomycosis, age, disposition of toes, and predisposing disease, as well as the type of shoes worn daily. We suspected that a patient's local and systemic conditions affected each other, creating good conditions for tinea pedis and onychomycosis so that the prevalence has increased. More understanding of occult athlete's foot will lead to prevention and improvement in treatment and diagnosis.
