目的通过了解镇江市麻疹流行病学特征,对麻疹监测系统运行质量进行评价,为进一步做好麻疹预防和控制工作提供科学依据。方法收集镇江市7个辖市区2009—2013年报告的麻疹监测系统数据,采用描述流行病学方法,分析麻疹流行病学特征、评价麻疹监测系统主要监测指标。结果镇江市2009—2013年年均排除病例报告发病率为2.56/10万,疑似病例血标本采集率从2009年的95.13%提高到2013年的100%,48 h个案调查率从2009年的95.13%提高到2013年的100%,血标本3 d内送达率从2009年的93.57%提高到2013年的100%,实验室血清学检测结果 7 d内报告率从2009年的94.28%提高到2013年的100%;麻疹发病具有较明显的季节性,发病高峰期集中在3—5月份,共140例,占总病例数的85.89%;发病年龄呈现“两头多,中间少”的分布态势;无免疫史或免疫史不详者占总病例数的90.18%,有免疫史者仅占9.82%。结论镇江市2009—2013年麻疹监测系统运转情况良好,麻疹监测系统运行质量逐年提高。应进一步提高麻疹监测工作质量、提高人群免疫水平、加强重点人群麻疹防控,继续维持消除麻疹目标状态。
Objective To understand the epidemiological characteristics of measles in Zhenjiang and evaluate the quality of measles monitoring system and provide a scientific basis for further prevention and control of measles. Methods The data of measles surveillance system reported in 2009 from 2009 to 2013 in 7 municipal districts of Zhenjiang were collected. The descriptive epidemiological method was used to analyze the epidemiological characteristics of measles and evaluate the main monitoring indicators of measles surveillance system. Results In 2009-2013, the annual average incidence rate of case-exclusion cases in Zhenjiang was 2.56 / 100,000. The blood sample collection rate of suspected cases increased from 95.13% in 2009 to 100% in 2013, and the case-rate of 48-h cases from 95.13 in 2009 % Increased to 100% in 2013, the delivery rate of blood samples within 3 d increased from 93.57% in 2009 to 100% in 2013, and the laboratory serological test results increased from 94.28% in 2009 to 100% in 2013; the incidence of measles was more obvious seasonal peak incidence peaked in March-May, a total of 140 cases, accounting for 85.89% of the total number of cases; age of onset showed “two more, less in the middle ” Distribution trend; No history of immunization or immunization Unknown account for 90.18% of the total number of cases, with only 9.82% of history of immunization. Conclusion The measles monitoring system in Zhenjiang City operated in good condition during 2009-2013, and the operation quality of measles monitoring system increased year by year. The quality of measles surveillance should be further improved, the population immunization level should be enhanced, the measles prevention and control of key populations should be strengthened, and the goal of eliminating measles should be maintained.
