Objective To understand the status of prevalence of human demodex infection on facial skin of clini- cal medicine profession undergraduates in a university. Methods A total of 560 samples from 140 undergraduatesof clinical medicine profession in a university were collected with the cellophane tape method in June, 2015. The slides were observed with a microscope. All the results were analyzed by using SPSS 17.0. Results The total infection rate of de- modex was 56.43% （79/140）, in which, the male and female infection rates were 55.71% （39/70） and 57.14% （40/70） re- spectively, and the difference between them was not statistically significant （P〉0.05）. The infection rates about oily, dry and neutral skins were 73.33 %（44/60）, 28.57 %（10/35） and 55.56% （25/45） respective/y, and the difference among them was statistically significant （P〈0.05）. The infection rate of demodex in patients with facial acne was 88.24% （45/51）, which was higher than 38.20% （34/89） of students without the disease （P〈0.05）. The infection rates of the students with heavy foodlik- ing, light food liking and no specific preference were 71.62% （53/74）, 53.57% （15/28） and 28.94% （11/38） respectively, and there was a significant difference among them. Conclusion Facial demodex widely exists on the face of the crowd, and there is no statistical significance between the female and male. The skin character, facial acne and food liking affect the demodex infection.
