目的对贵阳市2006-2012年疑似麻疹病例的实验室检测结果进行分析,为制定消除麻疹策略提供依据。方法收集贵阳市2006-2012年麻疹疑似病例监测资料,用Excel 2007进行数据统计分析。结果 2006-2012年贵阳市麻疹网络实验室共检测1 029例合格血标本,检出麻疹IgM阳性162例,占15.74%,1-12月每月均有麻疹阳性病例,2月为麻疹IgM阳性率最高峰(34.09%);麻疹IgM阳性以<8月龄和8月龄~1岁人群最多,风疹IgM阳性以7~14岁人群最多,有明确免疫史的疑似病例麻疹IgM抗体阳性率明显低于免疫史不详和0剂次的病例。结论免疫史不详和0剂次是麻疹发病的主要原因,提示要继续加强适龄儿童常规免疫,进而达到消除麻疹的目标。
Objective To analyze the laboratory test results of suspected measles cases from 2006 to 2012 in Guiyang, and to provide basis for formulating measles elimination strategies. Methods The surveillance data of measles suspected cases from 2006 to 2012 in Guiyang were collected and statistically analyzed with Excel 2007. Results A total of 1 029 qualified blood samples were detected in the measles network laboratory of Guiyang from 2006 to 2012. 162 cases of measles positive IgM were detected, accounting for 15.74%. Measles positive cases were found every month from January to December. Measles IgM was positive in February (34.09%). The positive rate of measles IgM was highest in <8 months old and 8 months old to 1 year old, and the positive rate of measles IgM was the highest in measles-like IgM positive cases Lower than the unknown history of immunization and 0 dose cases. Conclusion Unknown history of immunization and 0 doses are the main causes of measles, suggesting that we should continue to strengthen the routine immunization of school-age children, and thus achieve the goal of eliminating measles.
