目的内蒙古自治区在麻疹疫苗强化免疫前后的现场调查、评估,并对麻疹监测系统和传染病报告系统的疫情资料进行分析。方法所有8月龄～4岁儿童接种1剂麻疹疫苗,每剂次0.5mL。结果此次强化免疫接种儿童903 926人,调查和报告接种率均为97%以上;2010年麻疹发病人数明显减少,发病率仅2.83/10万,较2009年发病率6.03/10万下降53.07%;2010年麻疹监测系统数据显示,8月龄～4岁年龄组麻疹病例205例,与2009年相比麻疹发病率下降46.61%,57.29%的麻疹病例发生在8月龄～14岁,约85.80%病例无免疫史或免疫史不详,麻疹疫苗强化免疫疑似预防接种异常反应报告发生率为3.42/10万。结论高质量强化免疫是迅速控制麻疹流行、降低麻疹发病率的重要措施。为保持MV强化免疫取得的成果,必须提高常规免疫接种率,加强入托、入学查验预防接种证制度,使漏种儿童得到补种,同时在强化免疫后开展麻疹后续强化免疫。
Objective To investigate and evaluate the epidemic situation of measles surveillance system and infectious disease reporting system before and after the measles vaccine in Inner Mongolia Autonomous Region. Methods All children aged 8 months to 4 years were challenged with 1 dose of measles vaccine 0.5 mL per dose. As a result, 903 926 children were immunized with the vaccination coverage rate of more than 97%. The number of measles cases in 2010 decreased significantly, with a prevalence of only 2.83 / 100 000, a decrease of 53.07% from 6.03 / 100 000 in 2009 Measles surveillance system data in 2010 showed that in the age group of 8 months to 4 years, 205 cases of measles were detected, the incidence of measles decreased 46.61% compared with that of 2009 and 57.29% of measles cases occurred between August and 14 years old, about 85.80 % Of cases no history of immunization or history of immunization is unknown, measles vaccine immunization immunization suspected vaccination abnormal response to the report was 3.42 / 100,000. Conclusion High-quality intensive immunization is an important measure to control the epidemic of measles rapidly and reduce the incidence of measles. In order to maintain the success of MV, it is necessary to increase the routine immunization coverage rate, strengthen the system of vaccination certificates for nursery and entrance examinations so as to re-seed missing children and carry out intensified follow-up immunization after measles immunization.
