忻州市2008年麻疹特征及控制措施分析

Analysis on epidemiological characteristic and control measures of measles in Xinzhou city in 2008

目的分析忻州市2008年麻疹流行特征,为制定麻疹防控措施提供依据。方法利用描述流行病学分析方法,对2008年忻州市法定传染病报告系统麻疹疫情资料进行分析。结果忻州市2005年麻疹发病率9.37/10万,在当年全市强化免疫后,2006、2007年麻疹发病率维持在5/10万以下,2008年报告发病率为8.57/10万。发病以<15岁儿童为主,占总病例数的81.32%,所占比例较2007年(77.70%)升高,其中<8月和7～14岁组有所上升,8～11月和1～6岁组有所下降。结论在麻疹减毒活疫苗(Measles vaccine;MV)强化免疫后应切实提高常规免疫接种率,同时应提高MV 1剂及时接种率。提高易感人群MV免疫覆盖率,降低人群易感性是控制麻疹的首要措施,加强麻疹监测,适时开展高质量的MV强化免疫,管理传染源,切断传播途径是控制、消除麻疹的根本措施。

Objective To analyze measles epidemic prevention and control measures to provide basis for typical measles in Xinzhou city in 2008.Methods Using describing epidemiological methods epidemic information of measles from the typical infectious report system in 2008was analyzed.Results The reported measles incidence in Xinzhou city was 9.37/100 000.After the aggrandizement immunity（MV）,it was lower than 5/100 000 in 2006 and in 2007.However it was 8.57/100 000 in 2008.The proportion of measles case of 〈15 years old children was 81.23% in 2008 and higher than 77.70% in 2007.The proportion of measles in case of 〈8 months and 7 to 14 years old group increased,however 8-11 months and 1 ～ 6 years old groups decreased.Conclusions In MV aggrandizement immunity should improve after conventional,and improve MV 1 agent timely tailing off.Improving at-risk populations and reducing the MV immune coverage of measles is primary measures to control crowd susceptibility to strengthen the measles in high quality monitoring,and fundamental of MV aggrandizement immunity,management,cut transmitted infection to controlling measles.
