摘要
目的了解天津市2006年1-5月份学校流感流行特征，为开展防治工作提供依据。方法利用天津市2006年1-5月份“突发公共卫生事件报告管理系统”突发疫情报告及“疾病监测信息报告管理系统”传染病个案报告资料，进行回顾性病例个案调查。结果10起爆发疫情累计发病929例，平均罹患率为6．54％，均由乙型（Victoria系）流感病毒所致；集中出现在3-4月，波及8个区县10所中小学，5-12岁发病人数占所有病例的67.18％；首例发病至报告时间间隔中位数为8d，爆发持续时间中位数为21d。经检验，首例发病至报告时间间隔与罹患率（r=0.86，P=0.001）及疫情持续时间（r=0.68，P=0.031）之间均呈正相关。结论学校是易发生传染病爆发的场所，及时报告疫情、有效落实控制措施对于控制疫情十分重要。
Objective To explore the epidemiologie characteristics of influenza from January to May in 2006 in Tianjin, and to provide bases for prevention. Methods Using the date in Emergency Public Reporting System and Disease Monitoring Reporting System of Tianjin from January to May in 2006, retrospective study was carried out through investigating cases files. Results It was found that 10 influenza outbreaks including 929 cases were reported, caused by influenza B （Victoria）. The average prevalence accounted for 6.54%. Most of the outbreaks occurred in March and April, which spread in 10 primary and middle schools in 8 counties. Of all the reported cases, students aged 5 - 12 accounted for 67.18%. The median interval between occurrence of the initial case and its report was 8 days and the median of outbreak period was 21 days. Further analysis disclosed that positive correlation existed between the interval of the initial case to its report and influenza prevalence （r=0.86, P=0.001）, as well as between the interval of the initial case to its report and the outbreak period （r=0.68,P=0.031）. Conclusion Influenza is easy to lead to outbreaks in schools. Timely reports and effective prevention measures are very important for outbreaks control.
