Abstract

Considering that the contacts between travelers promote the epidemic spreading, this study constructed a spreading model with non-Markovian travel process and used computer simulation technology to simulate the epidemic spreading, where the time delay travel process and the infection and recovery during travel were considered on the metapopulation network. Based on the microscopic Markovian chain approach(MMCA), this paper developed a theoretical framework to predict the epidemic threshold. Simulation results indicate that the travel infection promotes the infection in travel but inhibits the infection within the subpopulations, and the travel time and the travel contact rate may change the time evolution of prevalence. These results help to understand the influence of travel infection on epidemic spreading.
