From October 1994 to December 1996, a prospective study was undertaken in 10,000 unselected school children in Madrid, aged between 2 and 16 years (mean +/- SD 8.5 +/- 3.6 years). Fifty-two (0.52%) (including 13 immigrants from Africa) had dermatophytes in the scalp: 33 (0.33%) (including 10 immigrants from Africa) had tinea capitis and 19 were scalp carriers. Almost half of the symptomatic cases were caused by Trichophyton tonsurans (12 of 33 cases) and Microsporum canis (16 of 33 cases). T. tonsurans (13 of 19 cases) was the predominant species in the scalp carriers. Twenty-four per cent of the subjects with tinea capitis and 42% of the asymptomatic scalp carriers also had ringworm in other body sites. There was a significantly higher occurrence of tinea capitis (P < 0.001) (particularly due to T. tonsurans: P < 0.001) and of asymptomatic scalp carriers (P < 0.05) (particularly due to anthropophilic species: P < 0.01) in the immigrant population from Africa.
1994年10月至1996年12月，对马德里10000名年龄在2至16岁（平均±标准差8.5±3.6岁）的未经过挑选的学童进行了一项前瞻性研究。52名（0.52%）（包括13名来自非洲的移民）头皮有皮肤癣菌：33名（0.33%）（包括10名来自非洲的移民）患有头癣，19名是头皮带菌者。几乎一半的有症状病例由断发毛癣菌（33例中的12例）和犬小孢子菌（33例中的16例）引起。断发毛癣菌（19例中的13例）是头皮带菌者中的主要菌种。24%的头癣患者和42%的无症状头皮带菌者在身体其他部位也有癣。来自非洲的移民人群中头癣（P<）的发生率显著更高。001）（尤其是由断发毛癣菌引起的：P<0.001）和无症状头皮带菌者（P<0.05）（尤其是由亲人性菌种引起的：P<0.01）。
