这项研究旨在分析温度、湿度和降雨量等气象条件如何影响新冠肺炎在巴西五个城市(圣保罗、里约热内卢、巴西利亚、马瑙斯和福塔莱萨)的传播。考虑到4月13日的数据，选定的城市是确诊病例最多的城市。变量包括累计病例数、每日新增病例数和污染率。我们的结果显示，较高的平均气温和平均相对湿度有利于新冠肺炎的传播，这与最冷国家或气温较低的一段时间的报告不同。因此，考虑到所取得的成果，跨部门政策和行动是必要的，主要是在污染率迅速上升的城市。因此，应在这些城市采取预防和保护措施，以减少传播和卫生系统可能崩溃的情况。(C)2020爱思唯尔B.V.保留所有权利。
This study aimed to analyze howmeteorological conditions such as temperature, humidity and rainfall can affect the spread of COVID-19 in five Brazilian (Sao Paulo, Rio de Janeiro, Brasilia, Manaus and Fortaleza) cities. The cities selectedwere thosewith the largest number of confirmed cases considering data of April 13. Variables such as number of cumulative cases, new daily cases and contamination rate were employed for this study. Our results showed that higher mean temperatures and average relative humidity favored the COVID-19 transmission, differently from reports from coldest countries or periods of time under cool temperatures. Thus, considering the results obtained, intersectoral policies and actions are necessary, mainly in cities where the contamination rate is increasing rapidly. Thus, prevention and protection measures should be adopted in these cities aiming to reduce transmission and the possible collapse of the health system. (C) 2020 Elsevier B.V. All rights reserved.
