By establishing a simulation model of infectious disease transmission based on interpersonal relationship, this paper studied the process of infectious disease transmission and the trend of epidemic development under relevant prevention and control measures. Described the contact and interaction between individuals based on the interpersonal relationship, this paper established an agent-based simulation model. It adjusted the model parameters based on the initial data collected by the Wuhan COVID-19 epidemic platform of the Chinese Health Commission, estimated the basic reproduction number (R0), and simulated the scenarios of different epidemic prevention and control methods, explored the trend of epidemic spread under different intervention measures. The established model for the spread of infectious diseases based on interpersonal relationships first simulated the spreading process of the Wuhan epidemic in the early stage, and estimated the COVID-19 R0 before Wuhan was closed to the public. Subsequently, the model preliminarily predicted the development trend of the epidemic in Yangzhou and found that the epidemic had entered a controllable stage. By discussing the impact of different intervention measures on the development of the epidemic in densely populated places (in the case of schools), this paper put forward relevant prevention and control opinions for the current students starting in the fall. Finally, it discussed the effect of the social movement distance of individuals in social contact networks on the epidemics transmission, and it was found that an increase in the social movement distance of individuals increased the risk of transmission of infectious diseases.

In recent years, with the in-depth development of information technology, its role in people's production and life has become increasingly prominent, and it has played a significant role in improving work efficiency. At the beginning of the new year in 2020, the novel coronavirus pneumonia (COVID-19) outbreak broke out in Wuhan City, Hubei Province and spread rapidly across the country. The country attaches great importance to it, and the medical staff acted quickly and actively participated in this war against the virus without the smoke of gunpowder. After arduous efforts from all over the country, our country's COVID-19 epidemic prevention and control situation has been further consolidated, and the prevention and control work has changed from an emergency state to a normal state of prevention and control. Hospital informatization construction is an objective requirement for hospital modernization and the prevention and control of the COVID-19, and it is of great significance in the context of the normalization of the COVID-19 epidemic prevention and control. This paper elaborates on the four aspects of hospital information construction in the background of COVID-19, the existing problems in hospital information construction, the practice of hospital information construction and the exploration of hospital informatization construction, and is committed to exploring the overall thinking of hospital information construction in special period.
