A new online tool, COVID-19 Simulator, developed by researchers at Massachusetts General Hospital (MGH) and Georgia Tech can help policy makers see how lifting or extending different social-distancing measures at various times can impact each state in terms of COVID-19 cases, hospitalizations, and deaths. The tool uses most recent data for each state and infectious disease modeling, as recommended by expert epidemiologists.


The tool offers different scenarios for the following interventions with varying lengths: lifting restrictions, extending a stay-at-home order (where people are advised to stay at home except for essential needs), and implementing a lockdown (as observed in countries like China, Italy, and India)—with consequences such as the rate of new cases, potential strain on the healthcare system, and projected deaths for each intervention.

A state-level analysis provides a view of trends in one state under different intervention policies; a state-by-state comparison provides a view of trends for multiple states at the same time, under different intervention policies; and a national-level analysis provides a view of trends for the United States as a whole under different intervention policies.
