目的探讨芜湖市麻疹流行特征,为完善预防控制措施,有效控制麻疹流行提供理论依据。方法对芜湖市1950-2008年麻疹监测报告资料及期间开展的麻疹防治相关资料进行分析。结果 1950-2008年芜湖市麻疹年平均发病率为92.51/10万,病死率为0.66%,麻疹发病率总体呈现随年代下降趋势,但有2～4年周期性升高现象;在推广使用麻疹疫苗后,麻疹发病显著下降,并较长时间维持低发病水平,但2005年后出现疫情的反弹,2008年出现地区性暴发疫情。2000年后病例年龄分布出现显著改变,小于1岁儿童、25～30岁2个年龄段病例显著增多。结论芜湖市麻疹发病率总体呈下降趋势,近年麻疹发病呈现疫苗后时期特征,提示相应免疫策略需要及时修订调整。
Objective To explore the epidemiological characteristics of measles in Wuhu City, providing theoretical basis for improving prevention and control measures and effectively controlling measles epidemic. Methods The data of measles monitoring from 1950 to 2008 in Wuhu City and the related data of measles prevention and control during the period were analyzed. Results The average annual incidence of measles in Wuhu from 1950 to 2008 was 92.51 / 100 000 with a case fatality rate of 0.66%. The incidence of measles was generally declining with age but with a periodic increase of 2 ~ 4 years. In the promotion of measles After the vaccine, the incidence of measles decreased significantly, and a relatively long time to maintain a low incidence, but the epidemic rebounded after 2005, a regional outbreak in 2008. After 2000, the age distribution of patients showed a significant change, less than 1 year old children, 25 to 30 years old two age groups increased significantly. Conclusions The incidence of measles in Wuhu generally shows a downward trend. In recent years, the incidence of measles shows the characteristics of post-vaccination, suggesting that the corresponding immunization strategies need to be revised in time.
