摘要
目的讨论集中度和圆形分布法在北京市房山区麻疹发病季节聚集特征和变化趋势分析中的应用,为科学防控麻疹提供依据。方法综合运用集中度和圆形分布法对北京市房山区2005—2015年麻疹发病情况进行变化趋势分析。结果 2005—2015年共报告麻疹病例659例,不同年份各季节分布有明显的季节性,差异有统计学意义(P<0.05)。发病高峰日是4月25日,流行期为2月25日—6月24日。病例数与风速、日照呈正相关,与流行期吻合。结论北京市房山区麻疹发病有较强的季节性,2—6月为流行高峰,集中度、圆形分布可用于麻疹季节流行特征描述,能定量反映疾病流行高峰和流行期。
[Objective] To explore the application of concentration degree and circular distribution methods in analysis of seasonality characteristics and changed tendency of measles in Fangshan District of Beijing,provide scientific evidence for prevention and control of measles. [Methods]Concentration degree and circular distribution methods were used to analyze the changed tendency of measles in Fangshan District of Beijing from 2005-2015.[Results]A total of 659 measles cases were reported from 2005-2015,and the difference in seasonal distribution was statistically significant among different years（P 0.05）. The average peak day was April 25,and the epidemic period was from February 25 to June 24. The number of cases was positively correlated with wind speed and sunshine time,which was in accordance with the epidemic period.[Conclusion]There are obvious seasonality characteristics of measles in Fangshan District of Beijing, and the epidemic period appears February to June.Concentration degree and circular distribution methods can be used for the description of seasonality characteristics of measles,and can quantitatively reflect the peak and epidemic period of measles.
