摘　　要：目的了解人群感染蠕形螨情况和流行规律及居住环境中物品污染情况,为科学防治提供依据。方法应用挤压刮拭法和透明胶纸粘贴法检验人体皮肤;采用透明胶纸法检验物器具。结果调查发现在校中学生感染率为48.05%,连续4次检查男、女人群感染率差异无显著性;蠕形螨人群感染随年龄增加而增多,对154名在校生的观察,人体蠕形螨感染具有家庭聚集性;宾馆房间物品检测,面巾和面巾挂杆污染率分别为0.07%和0.03%。结论蠕形螨人群感染具有家庭聚集性,外界物品可作为传播载体,防治人体蠕形螨应包括感染者和与感染者共同生活人群的治疗,对感染者居住环境中的物品应采取消杀等措施进行处理。Objective To investigate the trends in prevalence of Demodex-infested population and the mite distribution in household appliances, so as to provide scientific evidence for prevention and controlling of Dernodex infestation. Methods A number of Dernodex-infested population and household appliances were tested for Dernodex folliculorurn and Demodex brevis using the scraping method or the cellophane tape swab. Results The survey showed that the general positive rate was 63.84% in the Changsha area, and the positive rate increased with ageing. The survey also showed that the general positive rate of high school students was 48. 05%, and the positive rate went up yearly. Investigation of 154 students from different families showed that the Dernodex infestation featured a clustering of families. The examinations of hotel household appliances demonstrated that the Dernodex-contamination rates of towel racks and towels were 0.03 and 0.07%, respectively. Conclusion These results suggest that the positive rates of Dernodex infestation goes up yearly in the fixed group of investigated persons and the infestation features a clustering in families. The household articles may act as ＂vectors＂. Measures for treatment and prevention of Demodex infestation should include medication to both the infected patients and their close-contact members as well as application of pesticides to their living surroundings.
