Investigation on epidemiology of 214 cases of tinea manus and pedis

Objective:To analyze the epidemiological and clinical features of tinea manus and pedis.Methods:Two hundred and fourteen patients with tinea manus and pedis were set as research object to retrospective analysis,to find out the epidemilology and clinical characteristics of tinea manus and pedis.Results:More than 90% of the patients were infected by Trichophyton rubrum(tinea manus 63.1%,tinea pedis 71.0%) and Trichophyton tonsurans(tinea manus 9.8%,tinea pedis 15.4%).All patients with purely tinea manus were not checkouted with epidermophyton floccosum.Compared to purely tinea pedis,relevance ratio of candida albicans in purely tinea manus is obviously higher(tinea manus 22.0%,tinea pedis 5.6%).According to the degree of skin damage,tinea manus and pedis are divided into blister type,scale type and erosion type.As of epidemiology,20-40 years old are the high risk group,which contain 69.6% and about 45% are workman.In morbidity,scale type(tinea manus 62.1%,tinea pedis 77.1%) > erosion type(tinea manus 22.9%,tinea pedis 13.1%) > blister type(tinea manus 15.0%,tinea pedis 9.8%).Conclusions:Most of the tinea manus and pedis is caused by a minority of pathogenic bacterium.The morbidity have close relationship to what they touch and personal hygiene.Both the prevalence of tinea pedis and tinea manus have a rule of composition that is scale type >erosion type > blisters type.
