目的了解2009～2011年新疆阿克苏地区麻疹流行特征,探讨麻疹流行特征和发病特点。方法对2009～2011年阿克苏地区的麻疹监测资料进行描述性流行病学分析。结果 2009～2011年阿克苏地区累计报告51例麻疹病例,年均发病率2.06/10万;由于经过2008年麻疹强化免疫,不同年份间发病率的差异无统计学意义(χ2=6.00,P>0.05);3～5月为发病高峰,占总报告病例数的68.6%。结论新疆阿克苏地区麻疹病例中成人和未到免疫年龄段人群占较大比例,具有双向移位特征;要达到消除麻疹目标,在提高适龄儿童常规免疫接种率、疫苗成功率以及加强麻疹监测系统灵敏性的同时,建议适时开展成人强化免疫工作和提前麻疹疫苗初次免疫时间,进而达到消除麻疹的目标。
Objective To understand the epidemic characteristics of measles in Aksu region of Xinjiang from 2009 to 2011 and to explore the epidemiological characteristics and incidence of measles. Methods Descriptive epidemiological analysis of measles surveillance data in Aksu Prefecture from 2009 to 2011 was conducted. Results A total of 51 cases of measles were reported in Aksu from 2009 to 2011, with an average annual incidence of 2.06 / 100 000. There was no significant difference in the incidence of measles between 2008 and 2008 (χ2 = 6.00, P> 0.05 ); Peaked from March to May, accounting for 68.6% of the total reported cases. Conclusion Measles cases in Aksu region of Xinjiang have a large proportion of adults and immigrant age groups with bidirectional shift characteristics.
