An Epidemic Model with Isolated Intervention Based on Cellular Automata

Abstract

This paper presents a simulation modeling of epidemic with the isolated intervention based on the theory of Cellular Automata, which is considering the heterogeneity and mobility of the individuals. An idea of the random walk Cellular Automata is used to reflecting the characteristics of the mobility of individuals, by defining the proportion and the largest step of individuals’ movement. What’s more, the model simulates the impact of the disease duration and the isolated intensity on the spreading of epidemic, and the simulation result is coincidence with the macroscopic characteristics of epidemic controlled by isolation intervention. It offers powerful theoretical support for the government to prevent and control the spread of epidemic.
