[Research and reflection on the diversified method system of multi-stages and multi-scenarios surveillance and early warning of infectious diseases].

With the outbreak of infectious diseases, more and more attention has been paid to surveillance and early warning work. Timely and accurate monitoring data is the basis of infectious diseases prevention and control. Effective early warning methods for infectious diseases can improve the timeliness and sensitivity of early warning work. This paper briefly introduces the intelligent early warning model of infectious diseases, summarizes the emerging surveillance and early warning methods of infectious diseases, and seeks the possibility of diversified surveillance and early warning in different epidemic stages and different outbreak scenarios of infectious diseases. This paper puts forward the idea of constructing a diversified method system of infectious diseases surveillance and early warning based on multi-stages and multi-scenarios and discusses the future development trend of infectious diseases surveillance and early warning, in order to provide reference for improving the construction level of infectious diseases surveillance and early warning system in China.传染病的暴发流行让监测和预警工作受到越来越多的重视，及时、准确的监测数据是传染病防治工作的基础，有效的传染病预警方法能够提高预警工作及时性和灵敏度。本文简要介绍了传染病智能预警模型，总结了新兴的传染病监测预警方法，寻求在传染病不同流行阶段、不同暴发场景中开展多样化监测预警的可能性，提出构建传染病多阶段、多场景监测预警多样化方法体系的设想，探讨了传染病监测预警的未来发展趋势，为提升我国传染病监测预警体系建设水平提供参考。.
