目的评价天津市消除麻疹策略实施效果。方法采用描述流行病学方法对麻疹监测数据进行分析。结果2007年麻疹-流行性腮腺炎-风疹联合减毒活疫苗(MMR)纳入免疫规划及2008年、2010年2次MV强化免疫活动(SIAs)后,2012年麻疹发病率降至0.15/10万。麻疹病例<8月龄和≥15岁占绝大部分,构成比从2006年61.32%增加到2012年85.00%。麻疹监测系统特异性和及时性指标2012年均达到100.00%,但反映监测敏感性的指标——排除病例发病率仍低于2/10万。2006—2012年共报告25起麻疹暴发,暴发病例≥10例的有6起,占24.00%;暴发病例≤5例的有11起,占44.00%。结论天津市消除麻疹取得了一些进展,但监测敏感性仍有待提高,需要全面执行消除麻疹策略。
Objective To evaluate the effect of eliminating measles in Tianjin. Methods Descriptive epidemiological methods were used to analyze measles surveillance data. Results Incidence of measles-mumps-rubella combined live attenuated vaccine (MMR) in 2007 and measles immunization (SIAs) in 2008 and 2010 were reduced to 0.15 / 100,000 in 2012 . Measles cases <8 months of age and ≥15 years accounted for the vast majority, the composition ratio increased from 61.32% in 2006 to 85.00% in 2012. The specific and timely indicators of measles surveillance system reached 100.00% in 2012, but indicators of monitoring sensitivity - the incidence of exclusion cases was still below 2 / 100,000. A total of 25 measles outbreaks were reported in 2006-2012, out of a total of 10 cases, 6 outbreaks occurred, accounting for 24.00%. Outbreaks were less than 5 cases, accounting for 44.00%. Conclusion Some progress has been made in the elimination of measles in Tianjin. However, the sensitivity of monitoring needs to be improved. The elimination of measles should be fully implemented.
