This study investigated the effect of wind speed and air pollution on COVID-19 from March 10, 2020, to October 04, 2020, in Pakistan. Wind speed and COVID-19 had positive correlation in Pakistan and its provinces. The inverted U-shaped dose–response curve was found for wind speed and COVID-19 in Punjab. Initially, the dose–response curve showed a positive link between wind speed and COVID-19 in Pakistan, Sindh, Khyber Pakhtunkhwa, and Islamabad Capital Territory. Later, it becomes downward sloped in Sindh, Khyber Pakhtunkhwa, and Islamabad Capital Territory. The expected log count of COVID-19 was increased by 0.113 times (Pakistan), 0.074 times (Punjab), 0.042 times (Sindh), and 0.082 times (Khyber Pakhtunkhwa) for a 1 km/h increase in the wind speed. The correlation between particulate matter and COVID-19 was positive (Pakistan, Punjab, and Islamabad Capital Territory) and negative (Sindh). The dose–response curve for particulate matter and COVID-19 had inverted U-shaped (Pakistan, Punjab, and Khyber Pakhtunkhwa) positively sloped (Islamabad Capital Territory), and negatively sloped (Sindh). The inverted U-shaped association shows that the COVID-19 initially increased due to a rise in the particulate matter but reduced when the particulate matter was above the threshold level. The particulate matter was also responsible to wear face masks and restricted mobility. The expected log count of COVID-19 cases was reduced by 0.005 times in Sindh for 1 unit increase in particulate matter. It is recommended to reduce particulate matter to control respiratory problems. The government should use media (print, electronic, social) and educational syllabus to create awareness about precautionary measures.

本研究调查了巴基斯坦 2020 年 3 月 10 日至 2020 年 10 月 4 日期间风速和空气污染对 COVID-19 的影响。在巴基斯坦及其省份，风速与 COVID-19 呈正相关。在旁遮普邦发现了风速和 COVID-19 的倒 U 形剂量反应曲线。最初，剂量反应曲线显示巴基斯坦、信德省、开伯尔-普赫图赫瓦省和伊斯兰堡首都特区的风速与 COVID-19 之间存在正相关关系。后来，在信德省、开伯尔-普赫图赫瓦省和伊斯兰堡首都特区，它变得向下倾斜。风速每增加 1 公里/小时，预计 COVID-19 的对数计数将增加 0.113 倍（巴基斯坦）、0.074 倍（旁遮普邦）、0.042 倍（信德省）和 0.082 倍（开伯尔普赫图赫瓦省）。颗粒物与 COVID-19 之间的相关性为正相关（巴基斯坦、旁遮普邦和伊斯兰堡首都特区）和负相关（信德省）。颗粒物和 COVID-19 的剂量反应曲线呈倒 U 形（巴基斯坦、旁遮普邦和开伯尔-普赫图赫瓦省），正斜率（伊斯兰堡首都特区）和负斜率（信德省）。倒 U 形关联表明，COVID-19 最初由于颗粒物增加而增加，但当颗粒物高于阈值水平时减少。颗粒物也是戴口罩和限制行动的原因。在信德省，颗粒物每增加 1 个单位，预计的 COVID-19 病例数就会减少 0.005 倍。建议减少颗粒物以控制呼吸系统问题。政府应利用媒体（印刷媒体、电子媒体、社交媒体）和教育大纲来提高人们对预防措施的认识。
