目的调查不同人群人体蠕形螨的感染情况,探讨其与职业、性别、地域等的关系。方法采用略加改进的透明胶纸法。结果共检查583人,阳性率30.53%（178/583）。学生中阳性率随年级及年龄的增高而上升,其中小学与高中之间差异显著;不同职业中,银行职员与饮食服务人员阳性率最高,但不同职业之间、性别之间、城乡之间差异无显著性。感染者中以混合感染居多,感染部位以鼻尖鼻翼部、鼻唇沟部阳性率最高,感染度以轻度感染为主。患有痤疮、酒渣鼻、毛囊炎等皮肤疾病者与正常者阳性率差异有显著性（χ2=106.15,P〈0.05）。结论不同人群感染人体蠕形螨较为普遍,但在职业、性别、地域上的差异无显著性,以轻度感染为主,鼻部感染居多。其阳性率高低与年龄、个人生活习惯及面部皮肤有无疾患关系密切。
