目的了解内蒙古包头医学院大学生面部蠕形螨感染情况,为蠕形螨的防制提供理论依据。方法采用透明胶带粘贴法对包头医学院在校356名大学生面部蠕形螨感染进行抽样调查。结果该人群蠕形螨总感染率为19.94%,其中男生感染率为15.62%、女生感染率为22.37%,男女生感染率差异无统计学意义(P>0.05)。单纯毛囊蠕形螨感染占88.73%,单纯皮脂蠕形螨感染占4.25%,混合感染占7.04%。71例阳性感染者中,蠕形螨感染Ⅰ度为84.50%。蠕形螨的感染有季节消长规律,春季、夏季蠕形螨检出率高,冬季、秋季蠕形螨检出率低。结论内蒙古包头医学院大学生蠕形螨感染率处于相对较低水平。
Objective To understand the infection of Demodex mites on the face of college students in Baotou Medical College, Inner Mongolia, and to provide a theoretical basis for the prevention and control of Demodex mites. Methods A sample of 356 college students with vermiform mite infection from Baotou Medical College was sampled by the method of sticking tape. Results The total demodex infection rate was 19.94%. The male infection rate was 15.62% and the female infection rate was 22.37%. There was no significant difference between male and female infection rates (P> 0.05). Demodex folliculorum infection accounted for 88.73%, pure dermal vermiform mite infection accounted for 4.25%, mixed infection accounted for 7.04%. In 71 cases of positive infection, the degree of Demodex mite infection was 84.50%. Demodex mites infection with seasonal fluctuations in spring and summer Demodex detection rate is high, in winter and autumn Demodex detection rate is low. Conclusion The prevalence of Demodex in Baotou Medical College, Inner Mongolia is relatively low.
