Exposure to air pollutants has been associated with respiratory viral infections. Epidemiological studies have shown that air pollution exposure is related to increased cases of SARS-COV-2 infection and COVID-19-associated mortality. In addition, the changes of meteorological parameters have also been implicated in the occurrence and development of COVID-19. However, the molecular mechanisms by which pollutant exposure and changes of meteorological parameters affects COVID-19 remains unknown. This review summarizes the biology of COVID-19 and the route of viral transmission, and elaborates on the relationship between air pollution and climate indicators and COVID-19. Finally, we envisaged the potential roles of air pollution and meteorological parameters in COVID-19.

空气污染和气象参数在 COVID-19 中的新作用

接触空气污染物与呼吸道病毒感染有关。流行病学研究表明，空气污染暴露与 SARS-COV-2 感染病例和 COVID-19 相关死亡率的增加有关。此外，气象参数的变化也与COVID-19的发生和发展有关。然而，污染物暴露和气象参数变化影响COVID-19的分子机制仍不清楚。这篇综述总结了COVID-19的生物学和病毒传播途径，并详细阐述了空气污染和气候指标与COVID-19之间的关系。最后，我们设想了空气污染和气象参数在 COVID-19 中的潜在作用。
