Abstract:
The recent pandemic caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has increased the global concern over its transmission and prevention. Since there was an incontrovertible perception that environmental conditions might affect the spread of SARS-CoV-2, we analyzed the environmental variables impact on SARS-CoV-2 transmission in Pakistan. Our analytical study revealed that when the temperature remained high for consecutive 10 to 15 days, a significant decrease is witnessed in the forthcoming week in the COVID-19 cases. We found that a persistent high ambient temperature of 36 °C and above is detrimental to SARS-CoV-2 transmission and has paused the community spread of COVID-19 in Pakistan. Importantly, during the fall period of SARS-CoV-2, a high relative humidity of 63-72% was noted that showed a positive role in COVID-19 inhibition. Hence, the community spread of SARS-CoV-2 was paused by the warm humid climate and the ambient temperature was the yardstick in turning down the epidemic in Pakistan.
摘要:
最近由严重急性呼吸道综合症冠状病毒-2(SARS-CoV-2)引起的大流行增加了全球对其传播和预防的关注。由于人们无可争议地认为环境条件可能会影响SARS-CoV-2的传播,因此我们分析了环境变量对巴基斯坦SARS-CoV-2传播的影响。我们的分析研究表明,当温度连续10到15天保持高温时,未来一周,COVID-19病例显著减少。我们发现,36°C及以上的持续高环境温度不利于SARS-CoV-2的传播,并暂停了COVID-19在巴基斯坦的社区传播。重要的是,在SARS-CoV-2下降期间,观察到63-72%的高相对湿度在COVID-19抑制中显示出积极作用。因此,SARS-CoV-2的社区传播因温暖潮湿的气候而暂停,环境温度是减少巴基斯坦流行的标准。
