目的了解包河区2005年麻疹发病状况,为预防、控制麻疹提供科学依据。方法对包河区2005年麻疹监测系统报告的122例麻疹确诊病例进行流行病学分析。结果麻疹病例波及全区范围,发病率为30.17/10万,以高度散发形式存在,呈流行态势。发病高峰集中在4、5两月;发病年龄有双相移位现象,最小的3个月,最大36岁;男女性别比为1.18∶1;流动人口发病占总病例数的52.5%。结论流动人口的流入以及原发性和继发性免疫失败,是麻疹流行的主要原因。在今后的工作中,应该加强流动人口的免疫规划工作。 Objective To understand the incidence of measles in Baohe District in 2005 and provide a scientific basis for prevention and control of measles. Methods The epidemiological analysis of 122 cases of measles confirmed by the measles monitoring system in Baohe District in 2005 was conducted. The results of measles cases spread to the region, the incidence rate of 30.17 / 100,000, with a high degree of distribution of the existence of the epidemic situation. The incidence peak concentrated in 4,5 months; the age of onset of biphasic shift phenomenon, the youngest 3 months, maximum 36 years old; male to female ratio was 1.18: 1; floating population incidence accounted for 52.5% of the total number of cases. Conclusions The influx of floating population and the failure of primary and secondary immunizations are the major causes of measles epidemic. In the future work, we should strengthen the immunization planning of the floating population.
