In June 2020, the U.S., unlike other regions of the world, faced a surge in cases of COVID-19. Immediately prior to this wave of cases, the largest mass protests in U.S. history took place. We show that when holding other factors constant, COVID-19 cases increased most in places where more demonstrations occurred. We exploit variation in rainfall during the protest period as an exogenous source of variation in attendance. We find that good weather coincides with both more people protesting and more subsequent COVID-19 cases and deaths. Mass gatherings during a pandemic thus lead to more contraction and fatalities of COVID-19, and we quantify these effects.
2020年6月，与世界其他地区不同，美国面临新冠疫情病例激增的情况。就在这波病例出现之前，美国历史上规模最大的民众抗议活动发生了。我们发现，在其他因素保持不变的情况下，新冠疫情病例在示威活动较多的地方增加最多。我们利用抗议期间降雨量的变化作为参与人数变化的外部来源。我们发现，天气好的时候，抗议的人更多，随后新冠疫情的病例和死亡人数也更多。因此，疫情期间的大规模集会导致了更多的新冠病毒感染和死亡，我们对这些影响进行了量化。
