Emerg Infect Dis. 2020 Dec;26(12):3066-3068. doi: 10.3201/eid2612.201930. Epub 2020 Sep 21.


As coronavirus disease spreads throughout the United States, policymakers are contemplating reinstatement and relaxation of shelter-in-place orders. By using a model capturing high-risk populations and transmission rates estimated from hospitalization data, we found that postponing relaxation will only delay future disease waves. Cocooning vulnerable populations can prevent overwhelming medical surges.
