【摘要】：目的了解北京市朝阳区2006-2015年细菌性痢疾的流行病学和病原学特征,及时发现监测中存在的问题并改进,为今后的细菌性痢疾防控工作提供科学依据。方法采用描述流行病学方法,对2006-2015年北京市朝阳区细菌性痢疾的发病资料和病原学监测资料进行分析。结果 2006-2015年,北京市朝阳区共报告细菌性痢疾39 224例,平均报告发病率为121.62/10万,报告发病率呈下降趋势。层次聚类法根据细菌性痢疾的年平均报告发病率将2006-2015年划分为"高水平流行期"、"中等水平流行期"和"低水平流行期",3个流行期的菌痢报告发病率分别为:334.39/10万、160.26/10万和44.91/10万。3个时期的季节性不同(F=8280.29,P0.001),高流行期的高发季节为6-10月,中、低流行期均为5-10月。3个时期的地区分布不同,高流行期内地区的报告发病率高于街道(χ2=88.90,P0.001),中流行期内两者相同(χ2=0.34,P=0.558),低流行期内街道高于地区(χ2=50.02,P0.001)。3个时期的性别、年龄、人群分类构成、诊断类型等人群分布特征不同,菌株阳性检出率不同(χ2=10.29,P0.01)。在高流行期内主要以福氏志贺菌为主,从中流行期开始,变为以宋内志贺菌为主。结论 2006-2007年北京市朝阳区细菌性痢疾的监测数据不能真实反映其流行特征,应使用2008年以后的监测数据进行分析,才能真实地描述其流行规律。
[Abstract]:Objective to investigate the epidemiological and etiological characteristics of bacillary dysentery from 2006 to 2015 in Chaoyang District of Beijing, and to find out the existing problems in surveillance and improve them. Methods descriptive epidemiological method was used to analyze the incidence and etiological monitoring data of bacillary dysentery in Chaoyang District of Beijing from 2006 to 2015. A total of 39,224 cases of bacillary dysentery were reported in Chaoyang District, Beijing, with an average reported incidence of 121.62% -100 000. According to the average annual reported incidence of bacillary dysentery, the reported incidence rate was divided into "high level epidemic period", "middle level epidemic period" and "low level epidemic period" by hierarchical cluster method, and the three periods of bacillary dysentery were divided into three periods: "high level epidemic period", "middle level epidemic period" and "low level epidemic period". The reported incidence rates were: 334.39 / 100 000, 160.26% and 44.91% / 100,000, respectively. The seasonal differences in the three periods were 8280.29 and P0.001, and the high incidence season in the high epidemic period was June to October. In the middle and low endemic period, the distribution of the three periods was different. The reported incidence rate in the high epidemic period was higher than that in the street (蠂 2 88. 90% P 0. 001), and the two were the same in the middle epidemic period (蠂 2 + 0. 34%, P < 0. 558%). During the low epidemic period, the street was higher than that in the area (蠂 2 0. 02. 2. 02 P 0. 001), and the sex and age were higher in the period of high prevalence than that in the district (蠂 2 + 50. 02. P 0. 001). The positive detection rate of the strains was different (蠂 ~ 2 ~ 2 ~ (10.29) P _ (0.01)). Shigella flexneri was the main type in the high epidemic period, and it began to be in the middle of the epidemic period. Conclusion the monitoring data of bacillary dysentery in Chaoyang District of Beijing from 2006 to 2007 can not truly reflect the epidemic characteristics of Shigella sonnei. The surveillance data after 2008 should be used to analyze the epidemic pattern of bacillary dysentery in Chaoyang District of Beijing.
