目的了解宁波市2000~2005年麻疹流行病学特征,为制订消除麻疹策略提供依据。方法采用描述流行病学方法对法定传染病报告系统和麻疹监测系统资料进行分析。结果宁波市2000~2005年共报告麻疹2933例,年平均发病率为8.50/10万,城区发病率高于县(市)。流动人口发病987例,占33.65%。≥20岁成人、8月龄~7岁儿童、<8月龄婴儿,分别占39.44%、30.11%、14.12%。对1705例麻疹的免疫史分析,有麻疹减毒活疫苗(MV)免疫史、无免疫史、免疫史不详的分别占16.7%、48.6%、34.7%。结论本地人口发病增多,流动人口MV接种率低,提高MV接种率和加强麻疹监测,才能消除麻疹。
Objective To understand the epidemiological characteristics of measles in Ningbo City from 2000 to 2005 and provide the basis for formulating the measles elimination strategy. Methods Descriptive epidemiological methods were used to analyze notifiable infectious disease reporting systems and measles monitoring system data.

Adults ≥ 20 years, children aged 8 months to 7 years and infants <8 months old accounted for 39.44%, 30.11% and 14.12% respectively. Immunization history of 1705 cases of measles, measles live attenuated vaccine (MV) immunization history, no immunization history, unknown history of immunization were 16.7%, 48.6%, 34.7%. Conclusion The increase of local population, low vaccination rate of migrant population, increase of MV vaccination rate and monitoring of measles can eliminate measles.
