摘　　要：目的了解常州市武进区所有在校学生中流感样病例(influenza like illness,ILI)的分布,确定ILI防治的重点人群,为制定相应的预防措施提供科学依据。方法通过"常州市症状监测疾病预警系统",了解2007年武进区内所有在校学生中ILI的发生情况,并计算流感样病例的千分比(ILI,‰),探讨ILI的时间及地区分布特点。结果在本次研究中,共监测门诊学生1 796 729人次,其中流感样病例共7 286人次,ILI为4.06‰。全年中,ILI的发生呈现双峰分布,在春季和冬季ILI发病率较高,且冬末春初达到峰值。在监测区域内,西部区域流感样病例发病率最高,而北部区域最低。结论常州市武进区学生中,流感样病例在春季和冬季发病率较高;且在西部地区学校的流感样病例发病率较高,因此,应加强春冬两季流感样疾病预防宣传工作,并重点针对武进西部乡镇学校进行卫生宣传教育。Objective To explore the distribution of influenza like illness(ILI)among school studens in Wujin District,Changzhou City,and to provide basis for formulating scientific prevention and control measures.Methods The incidence rate of influenza like illness among students in Wujin District in 2007 was calculated according to the data from the Syndromic Surveillance Warning System.The time and regional distribution of the disease was explored.Results In this study,a total of 1 796 729 students were surveilled.The cases of ILI reached 7 286 with the proportion of 4.06‰.A bimodal distribution of influenza like illness in spring and winter was showed and the cases reached peak in winter-spring.The highest incidence rate occurred in the western part of the surveillence regions and the lowest incidence rate in the northern part.Conclusion The incidence rate of ILI is higher in spring and winter in Wujin District of Changzhou City and it′s also higher in schools of western part than in schools of eastern part.Therefore,it is necessary to strengthen the prevention of influenza like illness in spring and winter,especially in the town schools of western part of Wujin District.
