There are still many unknowns about COVID-19. We do not know its exact mortality rate nor the speed through which it spreads across communities. This lack of evidence complicates the design of appropriate response policies.
We source daily death registry data for 4100 municipalities in Italy's north and match them to Census data. We augment the dataset with municipality-level data on a host of co-factors of COVID-19 mortality, which we exploit in a differences-in-differences regression model to analyze COVID-19-induced mortality.
We find that COVID-19 killed more than 0.15% of the local population during the first wave of the epidemic. We also show that official statistics vastly underreport this death toll, by about 60%. Next, we uncover the dramatic effects of the epidemic on nursing home residents in the outbreak epicenter: in municipalities with a high share of the elderly living in nursing homes, COVID-19 mortality was about twice as high as in those with no nursing home intown.
A pro-active approach in managing the epidemic is key to reduce COVID-19 mortality. Authorities should ramp-up testing capacity and increase contact-tracing abilities. Adequate protective equipment should be provided to nursing home residents and staff.
关于 COVID-19,我们仍有许多未知之处。我们不知道其确切的死亡率,也不知道其在社区中传播的速度。这种证据的缺乏使制定适当的应对政策变得复杂。
我们从意大利北部 4100 个市镇的每日死亡登记处获取数据,并将其与人口普查数据相匹配。我们利用市镇一级的大量 COVID-19 死亡率的协变量数据来扩充数据集,并在差分模型中分析 COVID-19 引起的死亡率。
我们发现,在疫情的第一波中,COVID-19 导致当地超过 0.15%的人口死亡。我们还表明,官方统计数据大大低估了这一死亡人数,约为 60%。接下来,我们揭示了疫情对疫情中心的养老院居民的巨大影响:在养老院中老年人居住比例较高的市镇,COVID-19 死亡率是没有养老院的市镇的两倍。
积极主动地管理疫情是降低 COVID-19 死亡率的关键。当局应提高检测能力,并增强接触者追踪能力。应向养老院居民和工作人员提供足够的防护设备。
