Estimating the Risk of Infectious Disease Transmission

Minimizing the risk of importing and exporting infectious diseases like COVID-19 is a vital concern for public health. Risk assessment is essential for cities to establish effective border control measures. By utilizing passenger travel information from transportation network data, we employ stochastic metapopulation models, parameterized with infectious disease model characteristics, to estimate the risks of importation and exportation.
