菏泽市2009～2012年麻疹实验室监测分析

Analysis on laboratory results of measles surveillance in Heze city from 2009 to 2012

目的为提高当地麻疹监测系统（MSS）运转水平，做好麻疹监测和疫情应急处置工作，并为证实消除麻疹工作提供基础资料。方法对2009～2012年MSS实验室监测资料进行描述分析。结果2009～2012年报告麻疹疑似病例（MLI）分别为322例、485例、70例和6l例，确诊病例发病率（／10万）分别为2．98，4．75，0．37，0．11，实验室诊断病例分别为55例、52例、23例、2例。各年度MLI标本采集率在19．87％～83．61％，差异有显著性（P〈0．05），麻疹IgM检测后7日内报告率分别在52．94％-94．23％，差异有显著性（P〈0．05o麻疹发病呈散发，〈3岁年龄组病例占全部实验室诊断病例的51．52％（68／132o≥20年龄组占全部实验室诊断病例的32．58％（43／132），132例实验室确诊病例中，未有麻疹疫苗接种史者42．42％。结论全市近年来MSS运转情况正常，麻疹发病率得到控制，要关注〈8月龄的儿童和成人麻疹发病情况，并提出了提高麻疹疫苗接种率是今后工作的重点之一。

Objective In order to improve the operation level of Measles Surveillance System （MSS）, and to do a good job of measles epidemic monitoring and emergency handling work, and to provide the basic data for confirming measlds elimination. Methods Descriptive analysis was conducted on the data of laboratory surveillance of MSS in 2009-2012. Results 322,485,70 and 61 Measles-like Illnesses（MLI） were reported during the period of 2009- 2012 respectively, and the measles incidences（per 100000） were 2.98,4.75,0.37,0.11. 55, 52, 23 and 2 cases were confirmed through the laboratory diagnosis respectively. The collecting rate of blood serum samples of the cases was from 19.87% to 83.61%, significant differences found（P ~ 0.05）. The report rate of the blood serum samples after being tested within 7days was from 52.94% to 94.23%, significant differences found（P 〈 0.05）. The Laboratory diagnosis cases were confirmed sporadic measles cases. The groups aged under 3years accounted for 51.52%（68/132） in all the laboratory diagnosis cases, while the groups aged 20 years and above accounted for 32.58%（43/132）. Of all 132 laboratory diagnosis cases, there were 56 cases with no measles vaccination history, which accounted for 42.42%. Conclusion MSS was running normally, and the measles morbidity was under control. More attention should be paid to the measles situations among the groups aged under 8 months and among the adults. To raise measles vaccine coverage is one of the focuses in the nearly future.
