“The Coronavirus Disease 2019 Simulator (COVID-19 Simulator) is a tool to help policy makers decide how to respond to the novel coronavirus pandemic. The tool evaluates the impact of different social-distancing interventions (by varying their intensity and timing) on reduction in the spread of coronavirus in 50 states and District of Columbia. The information presented can help policymakers understand consequences such as the rate of new cases, potential strain on the healthcare system, and projected deaths. The COVID-19 Simulator combines infectious disease modeling and statistical modeling to simulate the trajectory of COVID-19 at the state level from March 15, 2020 to August 31, 2020 in the United States. Utilizing the most recent reported data for each state, the COVID-19 Simulator considers state-specific disease spread dynamics…”
