and propose an epidemic model
There are two types of nodes , individuals and public places ,
In this paper , we utilize a discrete - time Markov chain approach and propose an epidemic model to describe virus propagation in the heterogeneous graph , which is used to represent individuals with intra social connections and mobility between individuals and common locations .
There are two types of nodes , individuals and public places , and disease can spread by social contacts among individuals and people gathering in common areas .
