Comparison of SARS-CoV-2 Exit Strategies Building Blocks



  • The authors compare various exit strategy building blocks and measures to mitigate the current SARS-CoV-2 pandemic based on computerized simulations, finding significant differences in suppression among strategies with seemingly similar cost.  
  • The most effective strategies found integrate several base strategies, and allow for the release of large portions of the population. Stratified population release to achieve herd immunity did not perform well compared with other strategies. This information may help optimize exit strategies to be more effective and suitable for a particular area or country while maximizing human life and economic value.
