摘要

2020 年 2 月 21 日，欧洲首个冠状病毒病例群在意大利北部被正式检测到，尽管最近的证据显示，自 2019 年底以来，欧洲出现了零星的首例病例。在本研究中，我们检测了冠状病毒在意大利的存在情况，更重要的是，我们评估了病毒是否已在 2 月 21 日之前传播。我们采用了一种反事实方法，并认证了市一级的每日死亡人数（任何原因造成的死亡，不仅与冠状病毒有关）数据。我们的估计结果证实，冠状病毒于 1 月中旬开始在意大利北部传播。

When did coronavirus arrive in Europe?

The first cluster of coronavirus cases in Europe was officially detected on 21st February 2020 in Northern Italy, even if recent evidence showed sporadic first cases in Europe since the end of 2019. In this study, we have tested the presence of coronavirus in Italy and, even more importantly, we have assessed whether the virus had already spread sooner than 21st February. We use a counterfactual approach and certified daily data on the number of deaths (deaths from any cause, not only related to coronavirus) at the municipality level. Our estimates confirm that coronavirus began spreading in Northern Italy in mid-January.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
