目的 掌握麻疹流行特征,分析流行因素,为制定麻疹控制策略提供依据。方法 对42年的麻疹疫情进行统计,采用描述流行病学方法进行分析。结果随着麻疹疫苗的使用和计划免疫的实施,麻疹发病率大幅度下降,90年代后维持在较低水平;四季均有发病,以2～5月份为发病高峰;发病年龄主要为5～14岁人群;以局部地区暴发为主要流行形式,暴发疫情影响全县整体发病水平;麻苗常规免疫不扎实,局部地区存在免疫空白等是现阶段麻疹流行的根本原因。结论 抓好常规免疫,加强疫情监测,控制暴发是现价段防治麻疹的重要措施。 Objective To grasp the epidemiological characteristics of measles, analyze epidemic factors and provide basis for formulating measles control strategies. Methods The epidemic situation of measles in 42 years was statistically analyzed and described by epidemiological method. Results With the use of measles vaccine and the implementation of planned immunization, the incidence of measles dropped significantly and remained low after the 90s. The incidence of all the four seasons was peaked from February to May. The age of onset was mainly 5 to 14 Year-old population; outbreaks in some areas as the main form of epidemic outbreaks affect the overall incidence of the county level; Miao conventional immunization is not solid, there is immune blank in some areas is the root cause of measles epidemic at this stage. Conclusion Doing routine immunization, strengthening epidemiological surveillance and controlling outbreaks are the important measures to prevent measles at the current price.
