我们通过气候和空气污染指标（即平均温度、最低温度、最高温度、降雨量、平均相对湿度、风速以及空气污染指标 PM10、PM2.5 和 NO2）与 COVID-19 每日新增病例和死亡之间的相关性，评估了 SARS-CoV-2 在拉丁美洲和加勒比地区 (LAC) 的传播情况。该研究重点关注以下拉丁美洲和加勒比地区城市：墨西哥城（墨西哥）、圣多明各（多米尼加共和国）、圣胡安（波多黎各）、波哥大（哥伦比亚）、瓜亚基尔（厄瓜多尔）、马瑙斯（巴西）、利马（佩尔图）、圣地亚哥（智利）、圣保罗（巴西）和布宜诺斯艾利斯（阿根廷）。结果表明，平均气温、最低气温和空气质量与拉美和加勒比地区 COVID-19 的传播显着相关。此外，湿度、风速和降雨量与各个城市的每日病例数、总病例数和死亡率存在显着关系。收入不平等和贫困水平也被视为定性分析的变量。我们的研究结果表明，所分析城市的收入不平等和贫困水平分别与 COVID-19 阳性和阴性的传播有关。这些结果可能有助于决策者设计未来策略，以应对 COVID-19 在拉美和加勒比地区以及世界各地的传播。
We have evaluated the spread of SARS-CoV-2 through Latin America and the Caribbean (LAC) region by means of a correlation between climate and air pollution indicators, namely, average temperature, minimum temperature, maximum temperature, rainfall, average relative humidity, wind speed, and air pollution indicators PM10, PM2.5, and NO2 with the COVID-19 daily new cases and deaths. The study focuses in the following LAC cities: Mexico City (Mexico), Santo Domingo (Dominican Republic), San Juan (Puerto Rico), Bogota (Colombia), Guayaquil (Ecuador), Manaus (Brazil), Lima (Pertu), Santiago (Chile), Sao Paulo (Brazil) and Buenos Aires (Argentina). The results show that average temperature, minimum temperature, and air quality were significantly associated with the spread of COVID-19 in LAC. Additionally, humidity, wind speed and rainfall showed a significant relationship with daily cases, total cases and mortality for various cities. Income inequality and poverty levels were also considered as a variable for qualitative analysis. Our findings suggest that and income inequality and poverty levels in the cities analyzed were related to the spread of COVID-19 positive and negative, respectively. These results might help decision-makers to design future strategies to tackle the spread of COVID-19 in LAC and around the world.
