This article uses daily state information of the Social Isolation Index (SII) and recorded cases and deaths by COVID-19 for the period between March 13 and April 25, 2020 to estimate elasticities that relates these variables in Brazil. The results indicate that there was an adjustment period for social isolation to affect the number of cases and deaths in Brazil. From April, the estimated elasticity-isolation sat between -1.37 and -2.62 for COVID-19 cases, i.e., states that had a higher Social Isolation Index of 10% compared to others had on average 26.2% fewer COVID-19 cases. For deaths, the estimated elasticity-isolation is -1.79, i.e., states with a Social Isolation Index higher by 10% compared to another had on average 17.9% fewer deaths caused by COVID-19. Based on these results, the article concludes that measures that encourage voluntary social isolation are important to contain the spread of the virus, but that these measures should always be evaluated according to cost-benefit analysis.
