  新冠病毒是很多学子关注的事情,那么天气会影响新冠病毒传播吗?一起和天道小编看看约翰霍普金斯大学科学家的看法。

  天气会影响新冠病毒的传播吗?JHU气候科学家说现在下结论还为时过早

  Ben Zaitchik领导的一个国际工作组正在为研究气候、环境和气象因素如何影响疾病传播制定最佳标准

  约翰霍普金斯大学的地球和行星科学教授Ben Zaitchik正在领导世界气象组织的一个国际工作组,以开发最佳实践,以便对天气对新型冠状病毒的潜在影响进行准确评估。他说,仍然需要进行积极的研究,以确定气候、环境和气象因素是否以及如何影响新冠病毒传播。

  他还在美国国家航空航天局(NASA)的一个应用科学项目中工作,以调查可能的联系。

  “追踪和描述疾病传播对背景气候条件和季节性因素的敏感性既是一种迫切的需要,也是一种独特的机会,”Zaitchik在NASA工作的总结中说。关于季节性变异性和跨气候区传播差异的问题“已经被广泛讨论,而且高度不确定。”

  尽管缺乏足够的数据和同行评议的确认,但认为寒冷天气将在今年冬天引发另一波COVID-19大流行的研究已经开始影响世界各国政府的大流行应对政策。这个问题已经变得如此令人担忧,以至于世界气象组织就这个话题举行了为期三天的研讨会,并发布了一份声明,其中包括向世界领导人发出警告,称气候和COVID-19之间存在联系的明确声明还为时过早。

  该声明称:“目前同行评议的有关SARS-CoV-2病毒和COVID-19疾病的出版物没有显示出对温度、湿度、风、太阳辐射以及其他拟议的气象和环境驱动因素的强有力和一致的反应。”决策者应该注意不要依赖于预先审查的论文或单个研究的发现。所有的研究都应在上下文中仔细交流,以避免误解和误用信息。”

  Zaitchik补充说:“有理由预计,在寒冷干燥的冬季条件下,像COVID-19这样的呼吸道病毒性疾病的传播可能会增加,但在目前阶段,这一点的证据是复杂的。”

  Zaitchik说,世界气象组织的工作组正在努力为研究人员衡量气候、天气和环境因素对COVID-19的复杂影响的最佳方式制定标准。该工作组还将致力于建立伙伴关系,分享和讨论基于科学的见解,并相应地将它们分发给世界各地的政策制定者。

  他说:“我们要做的第一件事就是发表一份声明,说明如何做好研究。”

  Can weather affect spread of coronavirus? JHU climate scientist says too soon to tell

  Ben Zaitchik is leading an international task force developing best standards for researching how climate, environmental, and meteorological factors affect disease transmission

  Doug Donovan / Published 3 days ago

  Ben Zaitchik, a professor of Earth and planetary sciences at Johns Hopkins University, is leading an international task force of the World Meteorological Organization to develop best practices for producing accurate assessments on the potential impact of weather on the novel coronavirus. He says vigorous research is still needed to definitively determine if and how climate, environmental, and meteorological elements influence the spread of COVID-19.

  He is also working on a NASA applied sciences project to investigate the possible link.

  "There is both an urgent need and a unique opportunity to track and characterize the sensitivity of disease transmission to background climate conditions and to seasonal factors," states a summary of Zaitchik's NASA efforts. Questions about seasonal variability and transmission differences across climate zones are "already much debated and are highly uncertain."

  Studies that concluded cold weather will spur another major wave of COVID-19 this winter have begun to influence pandemic response policies by governments around the world, despite the lack of sufficient data and peer-reviewed confirmation. The issue has grown so worrisome that the WMO held a three-day symposium about the topic and released a statement that included a warning to world leaders that such definitive declarations of a link between climate and COVID-19 are premature.

  "Current peer-reviewed publications on the SARS-CoV-2 virus and the COVID-19 disease do not show a robust and consistent response to temperature, humidity, wind, solar radiation, nor other proposed meteorological and environmental drivers," the statement said. "Decision-makers should be attentive to not depend on pre-reviewed papers or findings of single studies. All studies should be communicated carefully and in context, to avoid misinterpretation and misuse of information."

  Added Zaitchik: "There are reasons to expect that transmission of a respiratory viral disease like COVID-19 might increase under the colder, drier conditions of winter, but at this stage evidence on this point is mixed."

  Zaitchik said the WMO task force is working to develop standards for the best ways researchers should measure the complex influences of climate, weather, and environmental factors on COVID-19. The task force will also work to form partnerships to share and discuss science-based insights and distribute them accordingly to policy makers around the world.

  "One of the first things we will do is release a statement about what it takes to do a good study," he said.
