面对世界卫生组织 (WHO) 于 2020 年 3 月 11 日宣布的新冠肺炎 (COVID-19) 全球大流行，以及更好地了解该病毒的季节性行为的需要，我们的团队进行了这项系统回顾，以描述目前对该病毒的出现和复制性及其与温度和相对湿度等不同天气因素的关系的了解。该评论已在 PROSPERO 数据库中注册。对电子数据库 PubMed、Scopus、Web of Science、Cochrane Library、LILACS、OpenGrey 和 Google Scholar 进行了检查，搜索仅限于 2019 年和 2020 年。使用乔安娜·布里格斯研究所 (JBI) 关键评估清单工具进行偏倚风险评估。 GRADE 工具用于评估证据的确定性。初步筛选确定了 517 篇文章。全文审查后，十七项研究符合审查的资格标准。关于温度和湿度对 COVID-19 季节性活力和传播性影响的研究结果存在很大的同质性。寒冷和干燥的条件是病毒传播的增强因素。经过质量评估，两项研究具有高偏倚风险，十一项研究被评为中等偏倚风险，四项研究被列为低偏倚风险。评估的两种结果的证据质量均被评为低。考虑到现有的科学证据，温暖潮湿的气候似乎会减少 COVID-19 的传播。然而，仅这些变量无法解释疾病传播的大部分变异性。因此，受该疾病影响最严重的国家应该关注卫生政策，即使气候不利于该病毒。尽管所产生的证据的确定性被归类为低，但纳入的研究报告的结果之间存在同质性。
Faced with the global pandemic of COVID-19, declared by World Health Organization (WHO) on March 11th 2020, and the need to better understand the seasonal behavior of the virus, our team conducted this systematic review to describe current knowledge about the emergence and replicability of the virus and its connection with different weather factors such as temperature and relative humidity. The review was registered with the PROSPERO database. The electronic databases PubMed, Scopus, Web of Science, Cochrane Library, LILACS, OpenGrey and Google Scholar were examined with the searches restricted to the years 2019 and 2020. Risk of bias assessment was performed using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist tool. The GRADE tool was used to assess the certainty of the evidence. The initial screening identified 517 articles. After examination of the full texts, seventeen studies met the review's eligibility criteria. Great homogeneity was observed in the findings regarding the effect of temperature and humidity on the seasonal viability and transmissibility of COVID-19. Cold and dry conditions were potentiating factors on the spread of the virus. After quality assessment, two studies had a high risk of bias, eleven studies were scored as moderate risk of bias, and four studies were classified as low risk of bias. The certainty of evidence was graded as low for both outcomes evaluated. Considering the existing scientific evidence, warm and wet climates seem to reduce the spread of COVID-19. However, these variables alone could not explain most of the variability in disease transmission. Therefore, the countries most affected by the disease should focus on health policies, even with climates less favorable to the virus. Although the certainty of the evidence generated was classified as low, there was homogeneity between the results reported by the included studies.
