Epidemiological Trends and Clinical Features of Trichophyton rubrum Infections: A 10-Year Retrospective Review of 38,391 Cases (2014-2023)

초록

Background: Trichophyton rubrum is the most common dermatophyte responsible for superficial fungal infections worldwide. This study provided a comprehensive epidemiological analysis of T. rubrum infections from 2014 to 2023, focusing on incidence trends, demographic characteristics, seasonal variation, and anatomical distribution. Methods: We retrospectively reviewed the medical records of 38,391 patients diagnosed with T. rubrum infections during a 10-year period. Data were analyzed regarding annual incidence patterns, demographics, seasonal trends, and clinical presentations. Results: T. rubrum consistently accounted for over 90% of all dermatophyte infections, although there was a slight decline in annual incidence. Individuals in their 50s constituted the most commonly affected age group, with significantly higher incidence rates observed in males. A marked seasonal peak occurred during the summer months. Tinea pedis was the most common clinical manifestation, followed by tinea unguium and tinea cruris. Conclusion: T. rubrum remains the leading cause of dermatophytosis, with stable demographic and seasonal infection patterns over the past decade. Preventive strategies focusing on older males, particularly during summer, may help reduce the prevalence of these infections.
