  • Results from an agent-based simulation model parametrized with data on Georgia population interactions and demographics over 7.5 months suggests that shelter-in-place followed by voluntary quarantine substantially reduced COVID-19 infections, resource needs, and severe outcomes. The combination reduced peak infections from approximately 180,000 under no intervention to below 53,000, and delayed the peak from April to July or later. Increasing voluntary quarantine compliance decreased daily new infections from almost 53,000 to 25,000, and decreased cumulative infections by about 50%.
