Abstract
Major epidemics of infectious diseases will not only endanger people’s lives and property, but also cause panic and social unrest. Therefore, it is particularly important to establish an infectious disease early warning system and take effective measures in time to prevent infectious disease outbreaks. The article summarizes the relevant definitions of infectious disease early warning system, domestic and foreign development status, infectious disease early warning models and methods, and aims to provide references for the establishment of infectious disease early warning systems.

Summary
There have been numerous public health emergencies around the world. After the first outbreak of COVID-19 in Wuhan in 2019, it has spread to a global epidemic. According to statistics from the official website of China 's Health Commission, as of 24:00 on December 1, 31 provinces (autonomous regions, municipalities) and the Xinjiang Production and Construction Corps reported that a total of 81649 cured and discharged cases, a total of 4634 deaths, and a total of 86,551 confirmed cases have been reported,and a total of 881,135 close contacts have been tracked, and 6,753 close contacts are still under medical observation. Constructing an indicator system, collecting relevant data, and establishing predictive models for early detection of infectious disease outbreaks and timely warnings, so as to take countermeasures, are currently important means of infectious disease prevention and control. The author has formed the research foundation of this article by searching the "Infectious Disease Early Warning", "Infectious Disease Early Warning Model", and "Infectious Disease Early Warning Index" in databases such as CNKI, Wanfang, and Weipu
