Abstract
Background: Tinea capitis remains a public health concern, especially in children, with evolving trends. Data from Nanchang, China, regarding comparative analyses between adults and children is limited.
Objectives: This study aimed to analyze the clinical and epidemiological characteristics, pathogen spectrum, risk factors, and household transmission of tinea capitis in Nanchang from 2022 to 2024, comparing features between adult and pediatric patients.
Methods: A single-center retrospective study was conducted involving 239 patients (170 children, 69 adults) diagnosed with confirmed tinea capitis. Demographic, clinical, and risk factor data were collected. Pathogens were identified via microscopy, culture, and molecular methods.
Results: Significant increases were observed in adult cases (28.87% vs. historical 9.73%), particularly among postmenopausal women. Anthropophilic pathogens dominated overall (65.42%), but zoophilic species increased significantly (32.71% vs. historical 16.96%). Clinical types differed: black dot tinea predominated in adults (81.16%), while kerion (42.94%) was more common in children. Animal contact was a key risk factor for children (55.29%). Household transmission occurred in 22.90% of surveyed families, with 100% pathogen concordance and frequent asymptomatic adult carriers (50% of affected households).
Conclusions: Notable differences exist between children and adult tinea capitis in Nanchang, with trends showing increasing adult cases and a shift towards zoophilic pathogens. Prevention strategies should be tailored to specific age groups and transmission modes, emphasising household screening and management of human and animal sources.
期刊介绍：
The journal Mycoses provides an international forum for original papers in English on the pathogenesis, diagnosis, therapy, prophylaxis, and epidemiology of fungal infectious diseases in humans as well as on the biology of pathogenic fungi.
Medical mycology as part of medical microbiology is advancing rapidly. Effective therapeutic strategies are already available in chemotherapy and are being further developed. Their application requires reliable laboratory diagnostic techniques, which, in turn, result from mycological basic research. Opportunistic mycoses vary greatly in their clinical and pathological symptoms, because the underlying disease of a patient at risk decisively determines their symptomatology and progress. The journal Mycoses is therefore of interest to scientists in fundamental mycological research, mycological laboratory diagnosticians and clinicians interested in fungal infections.
