摘要
目的了解四川省流感流行状况,为制定流感防制策略提供依据。方法用鸡胚和犬肾传代细胞分离病毒,用血凝抑制试验鉴定毒株。通过国家疾病监测信息报告管理系统、突发公共卫生事件报告管理信息系统和流感/人禽流感专报系统收集四川省流感及流感样病例(ILI)监测资料,对其流行病学、病原学以及流感暴发疫情监测结果进行分析。结果四川省ILI逐年减少,没有明显的就诊高峰。共报告流感暴发疫情9起,主要在3-4月,以农村中小学为主。在879份ILI标本中共分离到流感毒株100株,分离率11.38%。主要为H3型和B型,分别占52%和45%。结论需要加强四川省流感监测和流感病毒抗原变异研究,同时加强农村中小学暴发疫情监测。
Objective The study was conducted to evaluate the epidemiologic characteristics of influenza in Sichuan, providing evidence for the development of preventive intervention. Methods Embryonated egges and MDCK cells were used for viral isolation,and hemagglutination inhibition test performed to identify the isolates. Epidemiological, etiological and surveillance analysis was based on the data of influenza-like illness （ILI） and influenza cases collected through the national diseases reporting management system, public emergency reporting system and influenza surveillance information system. Results In Sichuan province, annual declining trend of ILI cases was present without significant clinicvisiting peaks. A total of 9 influenza outbreaks were reported, distributing mainly in March and April, and in rural elementary and middle schools. As a result, 100 isolates of influenza virus were collected from 879 ILl samples, the isolation rate being 11.38%. The predominant strains were of type H3 （52%） and B （45%）. Conclusion It is required to strengthen the flu surveillance and research on the antigen variation of influenza viruses. Meanwhile, considerations should be given to epidemic surveillance in countryside elementary and middle schools.
