目的 了解外来民工麻疹的免疫状况,探讨降低该人群发病危险因素的有效措施。方法随机抽取深圳市罗湖区外来民工为监测对象,采用酶联免疫吸附试验(ELISA)检测麻疹IgG抗体。结果共监测161人,麻疹IgG抗体阳性150人,抗体阳性率为93.17％,几何平均滴度(GMT)为1:966.5;在年龄、性别、户籍地等几方面的比较上,麻疹IgG抗体阳性率的差异都没有显著性。结论 外来民工的麻疹IgG抗体阳性率及GMT都达到了较高水平,提示目前在辖区内民工人群中发生大范围的麻疹暴发疫情的可能性不大。
Objective To understand the immune status of migrant laborer measles and to explore the effective measures to reduce the risk factors of this population. Methods Migrant workers in Luohu District of Shenzhen City were randomly selected as the monitoring objects, and measles IgG antibody was detected by enzyme-linked immunosorbent assay (ELISA). Results A total of 161 measles IgG antibodies were detected, with a positive rate of 93.17% and a geometric mean titer of 1: 966.5 (1 966.5). Measles IgG antibodies were positive in terms of age, sex and household registration No difference in rates was significant. Conclusions The positive rate of measles IgG antibody and GMT of migrant workers in migrant workers reached a high level, suggesting that there is not much possibility of a large outbreak of measles in migrant workers in the area at present.
