目的分析绵阳市2009—2012年麻疹病例流行病学特征及麻疹监测系统运转情况,为消除麻疹提供科学依据。方法收集整理2009—2012年绵阳市所有疑似麻疹病例个案资料、实验室检测结果和人口资料,用描述流行病学方法对该市麻疹流行病学特征及监测系统运转情况进行分析评价。结果绵阳市2009—2012年麻疹平均发病率为3.29/100万,病例人群分布主要是8月龄以下及15岁以上人群,发病时间集中在2—5月。该市麻疹监测系统的敏感性较低,但及时性和特异性指标均超过监测方案规定标准。结论绵阳市2~14岁人群麻疹防控工作开展较扎实,人群发病率低,但部分地区免疫规划工作还存在薄弱环节。麻疹监测系统敏感性还需提高。
Objective To analyze the epidemiological characteristics of measles cases and the operation status of measles surveillance system in Mianyang from 2009 to 2012 and provide a scientific basis for the elimination of measles. Methods The case data, laboratory test results and population data of all cases of suspected measles from 2009 to 2012 in Mianyang City were collected and analyzed. The epidemiological characteristics of measles and the operation of monitoring system in this city were analyzed and described. Results The average incidence of measles in Mianyang from 2009 to 2012 was 3.29 / 1 million. The distribution of cases in Mianyang was mainly below 8 months old and over 15 years old. The onset time was concentrated from February to May. Sensitivity of the city’s measles monitoring system is low, but the timeliness and specificity of indicators exceed the monitoring program standards. Conclusion The measles prevention and control work in 2 ~ 14 years old population in Mianyang City is relatively solid and the incidence rate of the population is low. However, immunization planning work in some areas still has weak links. Sensitivity to measles surveillance needs to be improved.
