目的了解近几年宜兴市本地与外来人口麻疹流行特征,为加速控制麻疹提供依据。方法对2004-2010年本地与外来人口麻疹发病特点进行流行病学分析。结果宜兴市麻疹发病为散发,本地人口平均发病率为2.31/10万,主要为15岁以上病例,于2-5月发病,以农民、散居儿童为主;流动人口平均发病率为17.10/10万,主要为7岁以下,于3-6月发病,以散居儿童、学生为主。本地人口发病率明显低于流动人口,且差异有统计学意义(χ2=537.67,P<0.001)。结论宜兴市麻疹发病率总体呈下降趋势,流行方式为散发。应加强常住人口与流动人口麻疹疫苗的初种与强化免疫工作,以控制流动人口发病为重点,并对大龄人群开展接种是控制麻疹发病的关键措施。
Objective To understand the epidemiological characteristics of measles in both local and foreign population in Yixing City in recent years and provide basis for accelerating the control of measles. Methods The epidemiological analysis of the incidence of measles in both local and foreign population from 2004 to 2010 was conducted. Results The incidence of measles in Yixing City was sporadic. The average incidence of local population was 2.31 / lakh, mainly for patients over 15 years of age. The incidence of measles was from February to May, with peasants and scattered children as the mainstay. The average incidence of floating population was 17.10 / 10 Million, mainly for 7 years of age, onset in March-June, to scattered children, students. The incidence of local population was significantly lower than the floating population, and the difference was statistically significant (χ2 = 537.67, P <0.001). Conclusion The incidence of measles in Yixing City generally shows a downward trend and the epidemic pattern is exuded. It is necessary to strengthen the initial vaccination and intensive immunization of measles vaccine among the resident population and floating population to focus on controlling the incidence of migrant population and to vaccinate the older population is the key measure to control the incidence of measles.
