流行性感冒(流感)是由于人类感染流感病毒而发生的一种急性呼吸道传染病,具有发病率高和迅速蔓延的特点。因此,运用预警方法识别早期流感疫情的异常升高以及流行迹象,使公共卫生部门尽早采取预防措施减少流感暴发或流行显得尤为重要。本研究就近年来常用流感预警方法进行归纳,综述各类预警方法基本原理、优缺点和应用状况,为流感预警方法的应用提供参考。
Influenza (influenza) is an acute respiratory infection that occurs as a result of human infection with the influenza virus, with a high prevalence and rapid spread. Therefore, the use of early warning methods to identify the anomalous rise of the early flu epidemic and the signs of the epidemic make it particularly important that public health authorities take early preventive measures to reduce the outbreak or outbreak of influenza. This study summarizes the early warning methods of influenza in recent years, summarizes the basic principles, advantages, disadvantages and application status of all kinds of early warning methods, and provides reference for the application of influenza early warning methods.
