We simulate the spread of disease within and between the 100 largest metropolitan areas in the United States. Disease is transmitted within cities according to a deterministic compartmental SEIR model (city model). Disease moves stochastically between cities via infected travelers (network model). In each simulation run we alternately simulate a week (i. e., 7 days) of disease transmission with...
