On April 7, 2020, Wisconsin held its presidential primary election, and news reports showed long lines of voters due to fewer polling locations. We use county-level variation in voting patterns and weekly county-level COVID test data to examine whether in-person voting increased COVID-19 cases. We find a statistically significant association between in-person voting density and the spread of COVID-19 2-3 weeks after the election. In our main results, a 10% increase in in-person voters per polling location is associated with an 18.4% increase in the COVID-19 positive test rate 2-3 weeks later.
2020年4月7日,威斯康星州举行了总统初选,新闻报道显示,由于投票地点减少,选民排起了长队。我们利用县级投票模式的差异和每周县级新冠病毒检测数据,来研究亲自投票是否增加了新冠病毒病例。我们发现,亲自投票密度与选举后2至3周新冠病毒的传播之间存在统计学上的显著关联。在我们的主要研究结果中,每个投票地点亲自投票的选民增加10%,与2至3周后新冠病毒检测阳性率增加18.4%相关。
