Tinea capitis remains a common public health problem worldwide, especially in developing countries.
To investigate the changes of the predominant dermatophytes of tinea capitis in children in Hangzhou in recent 9 years.
The age, gender and pathogen spectrum of 650 children with tinea capitis at the Department of Dermatology, Affiliated Third People's Hospital of Hangzhou, Anhui Medical University from 2011 to 2019 were analysed, and the distribution of pathogens from 1998 to 2000 was compared.
Among the 650 cases, 340 cases (48.2%) were males and 310 cases (51.8%) were females. The main population infected with tinea capitis was children aged 0-10 years (620 cases, 95.4%). From 2011 to 2019, the predominant dermatophyte was changed from Trichophyton violaceum (2011) to Trichophyton mentagrophytes complex (2012-2015) and later to Microsporum canis (2016-2019). In the past 9 years, M. canis (250 cases, 38.5%) was the most common dermatophyte and followed by T mentagrophytes complex (209 cases, 32.2%). The dermatophyte spectrum was statistically different between the years 2011 and 2019 (Chi square: χ = 69.75, P < .05), and the differences in anthropophilic and zoophilic pathogens between 1989-2000 and 2011-2019 were statistically significant (χ = 24.4, P < .05).
Research showed that children diagnosed with tinea capitis were mainly 0-10 years old. With age, the percentage of anthropophilic dermatophytes gradually increased, while the percentage of zoophilic dermatophytes decreased. M. canis was the predominant dermatophyte of tinea capitis in children, followed by T. mentagrophytes complex. The dermatophytes have shifted from anthropophilic to zoophilic dermatophytes in the past two decades.
头癣仍是全世界的一个常见公共卫生问题，尤其是在发展中国家。
调查杭州近 9 年来儿童头癣主要致病真菌的变化。
对安徽医科大学附属杭州市第三人民医院皮肤科 2011 年至 2019 年就诊的 650 例儿童头癣患者的年龄、性别和病原体谱进行分析，并与 1998 年至 2000 年的病原体分布进行比较。
650 例患者中，男 340 例（48.2%），女 310 例（51.8%）。头癣主要感染人群为 0-10 岁儿童（620 例，95.4%）。2011 年至 2019 年，优势致病真菌由紫色毛癣菌（2011 年）变为须癣毛癣菌复合群（2012-2015 年），随后变为犬小孢子菌（2016-2019 年）。9 年来，犬小孢子菌（250 例，38.5%）最常见，其次是须癣毛癣菌复合群（209 例，32.2%）。2011 年和 2019 年的真菌谱有统计学差异（卡方： χ ²=69.75，P ＜.05），1989-2000 年和 2011-2019 年亲动物性和嗜动物性真菌的差异有统计学意义（ χ ²=24.4，P ＜.05）。
研究表明，诊断为头癣的儿童主要为 0-10 岁。随着年龄的增长，亲动物性真菌的比例逐渐增加，而嗜动物性真菌的比例则下降。犬小孢子菌是儿童头癣的主要致病真菌，其次是须癣毛癣菌复合群。在过去的 20 年里，真菌已经从亲动物性向嗜动物性转变。
