A total of 462 patients living in varying socio-economic conditions were screened for tinea infection. 372/462 (70.7%) were found to be culture positive for dermatophytes. Trichophyton rubrum was the most frequently isolated dermatophyte. 35% of the infected cases were from the very low income group (group-I), 34.2% from low income group (group-II), 23.3% from middle income group (group-III) and 1.8% from moderately rich group (group-IV). Recurrent, chronic and extensive dermatophytosis were found to be most common in group-I (20.3%) and group-II (17.8%), whereas localized infections were common in group-IV (66.6%) and group-III (65.7%). Recurrence chronicity were more frequent in tinea cruris and tinea corporis. The present study suggests that group-I and group-II may be the likely reservoirs of human ringworm infections in Madras.
共对462名生活在不同社会经济条件下的患者进行了癣感染筛查。发现372/462（70.7%）的皮肤癣菌培养呈阳性。红色毛癣菌是最常分离出的皮肤癣菌。35%的感染病例来自极低收入组（第一组），34.2%来自低收入组（第二组），23.3%来自中等收入组（第三组），1.8%来自中等富裕组（第四组）。复发性、慢性和广泛性皮肤癣菌病在第一组（20.3%）和第二组（17.8%）中最为常见，而局限性感染在第四组（66.6%）和第三组（65.7%）中较为常见。股癣和体癣的复发和慢性更为频繁。本研究表明，第一组和第二组可能是马德拉斯人类癣感染的潜在储存宿主。
