The COVID-19 pandemic was a serious global health emergency in 2020 and 2021. This study analyzed the seasonal association of weekly averages of meteorological parameters, such as wind speed, solar radiation, temperature, relative humidity, and air pollutant PM2.5, with confirmed COVID-19 cases and deaths in Baghdad, Iraq, a major megacity of the Middle East, for the period June 2020 to August 2021. Spearman and Kendall correlation coefficients were used to investigate the association. The results showed that wind speed, air temperature, and solar radiation have positive and strong correlations with the confirmed cases and deaths in the cold season (autumn and winter 2020-2021). The total COVID-19 cases negatively correlated with relative humidity but were not significant in all seasons. Besides, PM2.5 strongly correlated with COVID-19 confirmed cases for the summer of 2020. The death distribution by age group showed the highest deaths for those aged 60-69. The highest number of deaths was 41% in the summer of 2020. The study provided useful information about the COVID-19 health emergency and meteorological parameters, which can be used for future health disaster planning, adopting prevention strategies and providing healthcare procedures to protect against future infraction transmission.
2020年和2021年，新冠疫情是一场严重的全球卫生突发事件。本研究分析了2020年6月至2021年8月期间，伊拉克首都巴格达（中东的一个主要大城市）风速、太阳辐射、温度、相对湿度和空气污染物PM2.5等气象参数的周平均值与确诊的新冠病例及死亡病例之间的季节性关联。采用斯皮尔曼和肯德尔相关系数来研究这种关联。结果表明，风速、气温和太阳辐射与寒冷季节（2020 - 2021年秋冬）的确诊病例及死亡病例呈正相关且相关性较强。新冠确诊病例总数与相对湿度呈负相关，但在所有季节中均不显著。此外，2020年夏季，PM2.5与新冠确诊病例密切相关。按年龄组划分的死亡分布显示，60 - 69岁人群的死亡人数最多。2020年夏季的死亡人数占比最高，为41%。该研究提供了有关新冠卫生突发事件和气象参数的有用信息，可用于未来的卫生灾难规划、采取预防策略以及提供医疗保健程序，以防范未来的感染传播。
