衢州市2007-2009年麻疹疑似病例IgM抗体检测结果分析

Analyzing results of Ig-M antibody in suspected measles in Quzhou during 2007～2009

目的：对2007-2009年衢州市麻疹疑似病例进行IgM抗体检测,通过结果分析麻疹流行特征,为制定防治措施提供依据。方法：采用酶联免疫吸附试验（EL ISA）对2007-2009年麻疹疑似病例血清标本进行IgM抗体检测。结果：2007-2009年共检测疑似病例259份,确诊149份,阳性率57.53%,2009年麻疹阳性率低于其它年。确诊病例的年龄主要集中在20~40岁,发病年龄有后移现象。麻疹发病高峰仍在冬春季。结论：保持疫苗高质量的常规免疫,重点加强大年龄组人群的强化免疫,并加大强化的力度,加强实验室的检测,有效控制麻疹的流行。

Objective To detect IgM antibodies in suspected cases of measles in Quzhou during 2007 and 2009,and to provide the basis for taking preventive measures.Methods Enzyme-linked immunosorbent assay（ELISA） was used for testing.Results 259 suspected cases were detected,149 confirmed,with a positive rate of 57.53%.In 2009 the positive rate of measles was significantly lower than that in other years.The age of confirmed cases was mainly in the group of 20 to 40 years old,the age of onset shifting to the older population.The peak incidence of measles is still in winter and spring.Conclusion It is necessary to maintain high-quality routine immunization,strengthen the intensive immunization of older population,and strengthen the laboratory testing so as to effectively control measles epidemic.
