摘要
目的探讨葫芦岛市细菌性痢疾发病的时间分布规律。方法 1990-2009年逐月和逐年细菌性痢疾疫情资料来源于辽宁省葫芦岛市疾病预防控制中心。利用描述统计分析细菌性痢疾季节发病规律,使用Cox-Stuart检验判定长期趋势,利用圆形分布法分析季节分布规律。结果 Cox-Stuart趋势检验的P值小于0.05,认为发病率存在逐年下降趋势。圆形分布法高峰时点为7月下旬,高峰时区为6月4日至9月14日。结论葫芦岛市的菌痢发病率存在下降趋势,应继续巩固现有的菌痢防控措施。
Objective To explore the variation of bacillary dysentery（BD） incidence in different period in Huludao.Methods Descriptive epidemiological analysis was conducted on the incidence data of BD from 1990 to 2009 reported by Huludao Municipal Center for Disease Control and Prevention,and Cox-Stuart test was performed to explore the secular trend.Finally,circular distribution method was adopted to analyze the seasonal distribution of BD incidence.Results The decline trend of BD incidence was found by Cox-Stuart test with statistical significance（P0.05）.The result of circular distribution method indicated that the incidence peak was in late July,and the peak period was from June 4 to September 14.Conclusion The decline trend of BD incidence was observed in Huludao,the current control measures should be strengthened.
