For anthropophilic tinea capitis (TC), household spread and asymptomatic scalp carriage (ASC) is considered an important route of transmission and incomplete clearance. To investigate ASC in household contacts of patients diagnosed with TC in a tertiary hospital in Athens, Greece, we retrospectively reviewed the medical files of household contacts that were screened for ASC from 1997 to 2011. Only 34 household contacts of 15 index cases agreed to come for screening. Thirty-three (97%) household contacts were asymptomatic scalp carriers. The most commonly isolated species was Trichophyton violaceum (59%). There was a statistically significant association of ASC with the isolated dermatophyte species (T. violaceum, P-value: 0.029), and with the age of younger than 16 years old (P-value: 0.005), while there was no association with gender (P-value: 0.672). A small number of household contacts accepted to proceed for screening. ASC was found in nearly all screened household contacts and was associated with T. violaceum and younger age. The low number of household contacts that accepted screening may reflect the ignorance of the general population about the possibility of ASC among household contacts in case of a patient with TC.
对于亲人性头癣（TC），家庭传播和无症状头皮携带（ASC）被认为是重要的传播途径和清除不完全的原因。为了调查希腊雅典一家三级医院中被诊断为TC的患者家庭接触者中的ASC情况，我们回顾性审查了1997年至2011年期间接受ASC筛查的家庭接触者的医疗档案。15例索引病例的家庭接触者中只有34人同意前来筛查。33名（97%）家庭接触者为无症状头皮携带者。最常分离出的菌种是紫色毛癣菌（59%）。ASC与分离出的皮肤癣菌菌种（紫色毛癣菌，P值：0.029）以及16岁以下年龄（P值：0.005）存在统计学上的显著关联，而与性别无关联（P值：0.672）。只有少数家庭接触者同意进行筛查。几乎所有接受筛查的家庭接触者都发现有ASC，且与紫色毛癣菌和年龄较小有关。接受筛查的家庭接触者数量较少可能反映出普通人群对TC患者家庭接触者中存在ASC可能性的忽视。
