Abstract: To exchange information, recurrent mobility of population occurs among different communities in the network. Many researches have shown that spreading process of diseases is affected by the mobility dynamics of population. In this paper, we use the discrete-time Markov-chain approach to study the spreading process of diseases with recurrent population mobility. The epidemic threshold is given. We analyze some factors that affect the spreading of infectious diseases, including community size, mobility ratio, and the number of communities. The results show that a small-scale community structure, high mobility ratio of community population and a large number of temporal communities are conducive to preventing infectious diseases. As the infectious rate is close to 1, the fraction of infected individuals is only determined by the recovery rate. The numerical simulations further support our conclusions.
