2019年冠状病毒病大流行(新冠肺炎)正在造成大量感染者和死亡。当前的问题之一是气候因素和环境污染如何影响新冠肺炎在人类社会的扩散。这项研究试图解释风速、空气污染和新冠肺炎扩散之间的关系，为遏制和/或预防未来的大流行和流行病提供见解。本文以意大利为例进行统计分析，发现两个主要发现：1)风速高的城市新冠肺炎感染人数较少；2)地处内陆地区(主要是与大城市接壤的城市)，风速小、空气污染频繁的城市新冠肺炎感染人数较高。这里的结果表明，与低风速相关的高浓度空气污染物可能会促进病毒粒子在城市污染空气中持续更长时间，从而有利于新型冠状病毒(SARS-CoV-2)的间接传播方式，以及人与人传播动力学的直接传播。
The pandemic of coronavirus disease 2019 (COVID-19) is generating a high number of infected individuals and deaths. One of the current questions is how climatological factors and environmental pollution can affect the diffusion of COVID-19 in human society. This study endeavours to explain the relation between wind speed, air pollution and the diffusion of COVID-19 to provide insights to constrain and/or prevent future pandemics and epidemics. The statistical analysis here focuses on case study of Italy and reveals two main findings: 1) cities with high wind speed have lower numbers of COVID-19 related infected individuals; 2) cities located in hinterland zones (mostly those bordering large urban conurbations) with little wind speed and frequently high levels of air pollution had higher numbers of COVID-19 related infected individuals. Results here suggest that high concentrations of air pollutants, associated with low wind speeds, may promote a longer permanence of viral particles in polluted air of cities, thus favouring an indirect means of diffusion of the novel coronavirus (SARS-CoV-2), in addition to the direct diffusion with human-to-human transmission dynamics.
