The new coronavirus, called 2019-nCoV, is a new type of virus that was first identified in Wuhan, China, in December 2019. Environmental conditions necessary for survival and spread of 2019-nCoV are somewhat transparent but unlike animal coronaviruses. We are poorly aware of their survival in environment and precise factors of their transmission. Countries located in east and west of globe did not have a significant impact on prevalence of disease among communities, and on the other hand, north and south have provided a model for relative prediction of disease outbreaks. The 2019-nCoV can survive for up to 9 days at 25 °C, and if this temperature rises to 30 °C, its lifespan will be shorter. The 2019-nCoV is sensitive to humidity, and lifespan of viruses in 50% humidity is longer than that of 30%. Also, temperature and humidity are important factors influencing the COVID-19 mortality rate and may facilitate 2019-nCoV transmission. Thus, considering the available and recent evidence, it seems that low temperatures, as well as dry and unventilated air, may affect stability and transmissibility of 2019-nCoV.
新型冠状病毒（2019-nCoV）是一种新型病毒，于 2019 年 12 月在中国武汉首次被发现。2019-nCoV 的生存和传播所需的环境条件有些透明，但与动物冠状病毒不同。我们对其在环境中的生存以及确切的传播因素知之甚少。位于地球东西两侧的国家对社区疾病的流行没有显著影响，而南北则为疾病爆发的相对预测提供了一个模型。2019-nCoV 在 25°C 下可存活长达 9 天，如果温度升高到 30°C，其寿命将会缩短。2019-nCoV 对湿度敏感，50%湿度下病毒的寿命比 30%湿度下长。此外，温度和湿度是影响 COVID-19 死亡率的重要因素，并可能促进 2019-nCoV 的传播。因此，考虑到现有的和最近的证据，似乎低温以及干燥和不通风的空气可能会影响 2019-nCoV 的稳定性和传染性。
