在所有欧洲国家中，意大利是第一个受到由严重急性呼吸综合征冠状病毒2号(SARS-CoV-2)引起的新冠肺炎大流行严重影响的国家。该病毒被证明具有很强的传染性，在全球范围内感染了900多万人(2020年6月)。然而，目前尚不清楚空气污染和气象条件对病毒传播的影响。在这项研究中，我们定量评估了意大利北部两个大城市米兰和佛罗伦萨以及特伦托自治省的气象和空气质量参数与新冠肺炎传播的相关性。米兰是伦巴第大区的首府，被认为是意大利疫情的震中。我们的主要发现强调了与温度和湿度相关的变量与病毒传播呈负相关，而空气污染(PM2.5)则呈正相关(程度较小)。换句话说，新冠肺炎大流行传播更喜欢干燥凉爽的环境条件，以及污染的空气。出于这些原因，病毒可能更容易在未经过过滤的空调室内环境中传播。这些结果将支持决策者遏制新的可能爆发的疫情。
Italy was the first, among all the European countries, to be strongly hit by the COVID-19 pandemic outbreak caused by the severe acute respiratory syndrome coronavirus 2 (Sars-CoV-2). The virus, proven to be very contagious, infected more than 9 million people worldwide (in June 2020). Nevertheless, it is not clear the role of air pollution and meteorological conditions on virus transmission. In this study, we quantitatively assessed how the meteorological and air quality parameters are correlated to the COVID-19 transmission in two large metropolitan areas in Northern Italy as Milan and Florence and in the autonomous province of Trento. Milan, capital of Lombardy region, it is considered the epicenter of the virus outbreak in Italy. Our main findings highlight that temperature and humidity related variables are negatively correlated to the virus transmission, whereas air pollution (PM2.5) shows a positive correlation (at lesser degree). In other words, COVID-19 pandemic transmission prefers dry and cool environmental conditions, as well as polluted air. For those reasons, the virus might easier spread in unfiltered air-conditioned indoor environments. Those results will be supporting decision makers to contain new possible outbreaks.
