Demodicosis is an infestation of the skin with Demodex, an ectoparasite commonly found on the face. A cross-sectional study was conducted to detect the presence of the ectoparasite and the outcome of facial cleanser and moisturizer usage on its infestation. Universal sampling was performed among 390 medical students, age 20-25 years old in the Klang Valley of Malaysia. The biodata of the participants and information on the use of facial cleanser and moisturizer were obtained through questionnaire. Skin samples were obtained using both skin scraping and cellophane tape method and were subsequently examined directly by microscopy. The results show an overall prevalence of 17.2%. Males (21.5%) were affected more often than females (12.8%) (p = 0.022). There were no significant differences in the prevalence of the ectoparasite among different ethnic groups, age-groups and the presence of existing facial problems among the subjects. A lower infestation rate (11.45%) was found to be associated with the use of a moisturizer (p = 0.033). Both species of ectoparasites that infest man, Demodexfolliculorum and D. brevis, were detected in this study either as single or mixed infestations.
蠕形螨病是由蠕形螨寄生于皮肤引起的疾病，蠕形螨是一种常见于面部的体表寄生虫。开展了一项横断面研究，以检测体表寄生虫的存在情况以及使用洁面产品和保湿产品对其感染情况的影响。对马来西亚巴生谷地区390名年龄在20至25岁之间的医学生进行了普查。通过问卷调查获取了参与者的生物数据以及使用洁面产品和保湿产品的信息。采用皮肤刮擦法和透明胶带法采集皮肤样本，随后直接进行显微镜检查。结果显示总体患病率为17.2%。男性患病率（21.5%）高于女性（12.8%）（p = 0.022）。在不同种族、年龄组以及受试者中现有面部问题的情况下，体表寄生虫的患病率没有显著差异。发现较低的感染率（11.45%）与使用保湿产品有关（p = 0.033）。本研究中检测到寄生于人体的两种体表寄生虫，毛囊蠕形螨和短蠕形螨，存在单一感染或混合感染的情况。
