目的分析采取不同免疫策略的地区流行性腮腺炎(流腮)疫情趋势,探讨不同免疫策略下流腮的流行病学特征。方法利用描述流行病学分析方法,对常规免疫实施两剂含流腮成分疫苗(Mumps-containing Vaccine,Mu CV)免疫策略的北京、天津、上海三个市和全国其他地区流腮疫情资料以及突发公共卫生事件信息进行分析。结果2004~2011年,全国流腮报告发病率呈逐年上升趋势。2008年以来,三个市流腮报告发病率呈下降趋势。全国流腮疫情呈规律的季节分布,每年存在冬季和夏季两个发病高峰,北京和上海市仅夏季高发。流腮报告发病率最高为5~9岁儿童,2008~2011年三个市5~9岁儿童流腮发病率较2004~2007年平均水平大幅下降,全国5~9岁儿童流腮发病率呈逐年上升趋势。2009年以来,三个市报告流腮突发公共卫生事件起数大幅下降并维持在低水平。结论实行两剂Mu CV常规免疫,有助于降低流腮高发人群发病率,有效地控制爆发疫情的发生。
Objective To analyze the epidemic trend of mumps (mumps) in different immunization strategies and to explore the epidemiological characteristics of mumps under different immunization strategies. Methods Descriptive epidemiological analysis methods were used to study the epidemic situation of mumps in Beijing, Tianjin and Shanghai and other parts of the country with two doses of Mumps-containing Vaccine (Mu CV) immunization strategy. Send public health event information for analysis. Results From 2004 to 2011, the incidence of cheongsam in China reported a rising trend year by year. Since 2008, the incidence of the three municipal cheeks has been on the decline. The epidemic of mumps in the country shows a regular seasonal distribution, with the peak incidence in winter and summer each year, with only summer in Beijing and Shanghai. The incidence of mumps reported the highest incidence of children aged 5 to 9 years, from 2008 to 2011 three cities 5 to 9 years old children gobal incidence rate dropped significantly from 2004 to 2007 the average level of 5 to 9 years old children across the country gout morbidity was Increasing trend year by year. Since 2009, the three cities have reported a sharp drop in the number of public health incidents of gully attacks and kept them at a low level. Conclusions The two-dose routine immunization with Mu CV will help to reduce the morbidity of high-risk grifolic cheeks and effectively control the outbreak of outbreaks.
