A comparison of lockdown measures and counts of COVID-19 cases across 9 countries using an SIR-based epidemic model found that lockdown policies were effective in reducing SARS CoV-2 infections. The models discerned two groups of countries. The first group included Sweden and the United States, which had either no lockdowns or abruptly ended lockdown policies and exhibited a prolonged plateau of new infections and higher values of R0. The second group of countries (New Zealand, France, Spain, Germany, the Netherlands, and Italy) had early-onset stay-at-home orders followed by gradual deconfinement associated with a rapid reduction in infected individuals and lower R0 during the study period of February 23, 2020 to June 14, 2020.
