  1. Most of these parameters are an estimation from various sources to reflect the US population pre-pandemic. The network size of 10,000, while clearly more representative of a small town than of a country, allows computationally efficient simulation and rich outcomes of the disease spread. The parameters can be changed in the code (see “Methods” section)
