Tinea manuum is a common superficial fungal infection which is usually coexistent with tinea pedis; there are few studies available on the epidemiology of tinea manuum at present. This study aims to investigate the epidemiology of tinea manuum and its correlation with tinea pedis in south China. A total of 280 patients with tinea manuum were recruited. The epidemiological and clinical data were analyzed, and causative agents were isolated and identified mycologically. Totally, 84.3 % patients with tinea manuum had co-occurrence of tinea pedis, among which 88.4 % patients had experience of scratching their feet. There was a significant relationship between the touch habits and the hand infection (χ(2) = 65.451, P = 0.000). More than 90 % patients had quite the same species of isolates from multiple infected sites in one patient. Therefore, it seems that transmission of dermatophytes from the feet to hand by scratching might be a most common way. As for tinea manuum, whether "unilateral" or "bilateral" is just the result that pathogens spread from feet to hand(s), which is only a special clinical presentation of tinea.
手癣是一种常见的浅部真菌感染，通常与足癣同时存在；目前有关手癣的流行病学研究较少。本研究旨在调查中国南方地区手癣的流行病学及其与足癣的相关性。共招募了 280 例手癣患者。分析了流行病学和临床资料，并进行了真菌学分离和鉴定。共有 84.3%的手癣患者合并足癣，其中 88.4%的患者有抓挠脚部的经历。抓挠习惯与手部感染之间存在显著关系（χ(2) = 65.451，P = 0.000）。超过 90%的患者在同一患者的多个感染部位分离出相同的菌种。因此，似乎通过抓挠将足癣的皮肤癣菌传播到手部是最常见的方式。对于手癣，“单侧”还是“双侧”只是病原体从足部传播到手部的结果，这只是体癣的一种特殊临床表现。
