目的通过对江都区健康人群麻疹抗体水平检测和分析,掌握该区麻疹免疫水平,为麻疹预防控制工作提供科学依据。方法抽取4个乡镇0~40岁健康人群,分7个年龄组,每个年龄组80人,采用ELISA法检测麻疹Ig G抗体,检测结果用Excel建立数据库,用SPSS 17.0统计软件进行统计分析。结果共采样542份,麻疹Ig G抗体阳性率为65.50%,抗体几何平均滴度为1:359.37,保护性抗体阳性率为29.33%。结论小于8月龄和15岁以上人群以及流动人口麻疹抗体水平较低,存在罹患和疫情爆发的风险,建议在以上人群中开展麻疹疫苗查漏补种或强化免疫工作。
Objective To detect and analyze measles antibody levels in healthy people in Jiangdu District and to understand the level of measles immunity in this area to provide a scientific basis for the prevention and control of measles. Methods Four healthy people from 0 to 40 years old in township were selected and divided into seven age groups of 80 in each age group. Ig antibody against measles was detected by ELISA. The data were collected by Excel and analyzed by SPSS 17.0 software. Results A total of 542 samples were collected. The positive rate of measles IgG antibody was 65.50%. The geometric mean antibody titer was 1: 359.37. The positive rate of protective antibody was 29.33%. Conclusions The level of measles antibody in the population less than 8 months old and above 15 years old and floating population is low, so there is a risk of suffering from and outbreak of epidemic. It is recommended to carry out leak vaccination or intensive immunization in the above population.
