目的分析2004-2009年永嘉县麻疹流行病学特征,探索有效防控措施,为预防保健工作提供科学依据。方法 将病例资料导入Excel 2003和SPSS 10.0统计软件及DPS 12.01版数据处理系统,并运用圆形分布法进一步研究疾病的时间分布特征。利用Poisson分布的μ检验分析疾病分布的性别差异。用描述流行病学分析方法对麻疹发病的时间、年龄和性别等人群分布特点进行分析。结果 2004-2009年累计报告麻疹病例1 063例,年平均报告发病率为19.50/10万,2008年达47.59/10万;发病的高峰日在4月中下旬,高峰期为1月24日~7月11日,发病呈一定的季节性;男女发病率差异有统计学意义(χ2=3.885,P<0.05),男性发病率高于女性;≤8月龄婴儿和成人麻疹患者发病人数在总患病人数中比例上升,各占约25%左右。结论 近年来麻疹疫情有所回升,2008年本地区麻疹呈高发流行态势。≤8月龄婴儿和成人麻疹患者发病人数在总患病人数中比例上升,高发季节向后推移。
Objective To analyze the epidemiological characteristics of measles in Yongjia County from 2004 to 2009, explore effective prevention and control measures, and provide scientific basis for preventive health care. Methods The case data were imported into Excel 2003 and SPSS 10.0 statistical software and DPS 12.01 data processing system. The circular distribution method was used to further study the time distribution of the disease. The use of Poisson distribution of μ test analysis of the gender distribution of the disease. The descriptive epidemiological analysis was used to analyze the population distribution characteristics of measles such as age, gender and other factors. Results A total of 1 063 measles cases were reported in 2004-2009, with an average annual incidence rate of 19.50 / 100 000 and 47.59 / 100 000 in 2008; the peak incidence day was in mid to late April and the peak was January 24 ~ July 11, the incidence was a seasonal; gender differences were statistically significant (χ2 = 3.885, P <0.05), the incidence of men than women; ≤ 8 months of age infants and adult measles patients in the total number The proportion of sick people increased, each accounting for about 25%. Conclusion The measles epidemic has rebounded in recent years. In 2008, measles in the area showed a high prevalence. The incidence of measles patients ≤ 8 months of age and adults increased in the total number of cases and the postponement of the high incidence season.
