目的了解2005-2009年内蒙古自治区麻疹流行特点,为控制麻疹提供科学依据。方法根据内蒙古自治区传染病报告系统和年度麻疹发病统计表,对2005-2009年麻疹发病资料进行分析。结果 2005-2009年内蒙古自治区共报告麻疹病例12 187例,年均发病率为10.17/10万,2005年发病率最高,达14.97/10万;2009年发病率最低,为6.03/10万。不同年份间麻疹发病率差异有统计学意义(P<0.01)。各盟市均有病例报告,不同地区间麻疹发病率差异有统计学意义(P<0.01)。各月份均有发病,以3～6月份发病最多,占77.6%。发病年龄属混合模式,以1～14岁为主,占40.3%,同时出现双向移位现象,即大年龄组(≥15岁)和<1岁组病例数增加,分别占病例总数的42.0%和17.7%。结论针对易感人群麻疹强化免疫可降低麻疹发病,为提高人群免疫水平,应进一步加强麻疹复种和查漏补种工作。
Objective To understand the epidemic characteristics of measles in Inner Mongolia Autonomous Region from 2005 to 2009 and provide a scientific basis for measles control. Methods According to the infectious disease reporting system in Inner Mongolia Autonomous Region and the annual measles incidence statistics, the incidence of measles in 2005-2009 was analyzed. Results A total of 12 187 cases of measles were reported in Inner Mongolia Autonomous Region from 2005 to 2009, with an average annual incidence of 10.17 / 100 000. The highest incidence rate in 2005 was 14.97 / 100 000. The lowest incidence in 2009 was 6.03 / 100 000. The incidence of measles in different years was significantly different (P <0.01). Each city has a case report, the incidence of measles between different regions was statistically significant (P <0.01). The incidence of each month, the most incidence in March to June, accounting for 77.6%. The age of onset belongs to the mixed mode, which is mainly aged from 1 to 14 years old, accounting for 40.3%. At the same time, there is a two-way shift phenomenon, that is, the number of cases in large age group (≥15 years old) and <1 year old group increased, accounting for 42.0% And 17.7%. Conclusion Measles-specific immunization against susceptible populations can reduce the incidence of measles. To improve the population’s immune level, multiple measles vaccination and missed-vaccination should be further strengthened.
