麻疹疑似病例141例血清中IgM抗体检测结果及病例分析

目的探讨检测麻疹IgM抗体对分析麻疹流行病学特征的意义。方法对江苏省如东县2006—2009年141例麻疹疑似病例采集血清标本,应用酶联免疫吸附试验(ELISA)捕获法检测麻疹IgM抗体,对检测结果应用χ2检验进行统计学处理。结果 141例麻疹疑似病例血清标本,麻疹IgM抗体阳性109例,阳性率77.30%。11～20岁年龄组阳性率最高,达90.32%;31～40岁组次之,为84.78%。在病例的职业构成中农民占45.68%。在病例的免疫史分布中,无免疫史、免疫史不详者合计达69.14%。结论该县麻疹发病有向大年龄组发展的趋势,农民为重要的发病人群。加强麻疹疫苗接种管理尤其是农村的管理、针对成人的后续强化免疫和应急接种对控制疫情的传播具有重要意义。
