COVID-19大流行正在地球仪造成现代社会从未见过的浩劫。尽管SARS-Cov-2的传播途径至关重要，但各部门仍在争论。这里收集的证据强烈表明，COVID-19可以在通风不足的环境中通过空气传播。现有的实验数据表明，臭氧、高温和低湿度会对冠状病毒的存活产生负面影响。在这里，回归分析表明，随着环境臭氧浓度水平从48.83 μ g/m3增加到94.67 μ g/m3，SARS-Cov-2的传播减少（p值= 0.039）和相对湿度从23.33%降至82.67%（p值= 0.002）和温度为-13.17至19摄氏度）（p值= 0.003）。除了利用这些环境影响外，强烈鼓励保持社交距离和佩戴口罩，以最大限度地对抗COVID 19的空气传播。现在正是社会迫切需要世界各地各学科科学家共同应对这一灾难性流行病的时候。(C)2020爱思唯尔B.

The COVID-19 pandemic is creating a havoc situation across the globe that modern society has ever seen. Despite of their paramount importance, the transmission routes of SARS-Cov-2 still remain debated among various sectors. Evidences compiled here strongly suggest that the COVID-19 could be transmitted via air in inadequately ventilated environments. Existing experimental data showed that coronavirus survival was negatively impacted by ozone, high temperature and low humidity. Here, regression analysis showed that the spread of SARS-Cov-2 was reduced by increasing ambient ozone concentration level from 48.83 to 94.67 mu g/m(3) (p-value= 0.039) and decreasing relative humidity from 23.33 to 82.67% (p-value= 0.002) and temperature from-13.17 to 19 degrees C) (p-value = 0.003) observed for Chinese cities during Jan-March 2020. Besides using these environmental implications, social distancing and wearing a mask are strongly encouraged to maximize the fight against the COVID19 airborne transmission. At no other time than now are the scientists in various disciplines around the world badly needed by the society to collectively confront this disastrous pandemic. (C) 2020 Elsevier B.V.
