Aiming at the problem of the spread of infectious diseases in a closed system, this paper uses the Runge-Kutta method to construct a prediction model based on improved SIR infectious disease infection and a SEIRD model based on causality, and comprehensively use MATLAB and other software programming to solve the problem. The number of people infected with infectious diseases increased first and then decreased and eventually tended to zero, and the number of people infected with infectious diseases was related to the daily contact rate between the latent and the population. After the staff took preventive and control measures, the rate of transmission of infectious diseases decreased and the number of people transmitted decreased.
