Abstract: Methods, systems, and computer programs are presented for estimating disease-spreading based on facility and behavioral parameters. One method includes an operation for causing presentation of a user interface (UI) for entering facility parameters. The method further includes an operation for calculating the number of infections at the facility for a predetermined time period. The calculation includes setting values for simulation parameters based on the facility parameters, modeling a contact network for people at the facility, and performing a plurality of simulations to determine the number of infections, the plurality of simulations based on the contact network and the facility simulation parameters. Further, the method includes an operation for causing presentation of the number of infections in the UI.
