Several epidemiological studies have suggested a link between air pollution and respiratory tract infections. The outbreak of coronavirus disease 2019 (COVID-19) poses a great threat to public health worldwide. However, some parts of the globe have been worse affected in terms of prevalence and deaths than others. The causes and conditions of such variations have yet to be explored. Although some studies indicated a possible correlation between air pollution and COVID-19 severity, there is yet insufficient data for a meaningful answer. This review summarizes the impact of air pollution on COVID-19 infections and severity and discusses the possible management strategies and challenges involved. The available literature investigating the correlation between air pollution and COVID-19 infections and mortality are included in the review. The studies reviewed here suggest that exposure to air pollution, particularly to PM2.5 and NO2, is positively correlated with COVID-19 infections and mortality. Some data indicate that air pollution can play an important role in the airborne transmission of SARS-CoV-2. A high percentage of COVID-19 incidences has been reported in the most polluted areas, where patients needed hospital admission. The available data also show that both short-term and long-term air pollution may enhance COVID-19 severity. However, most of the studies that showed a link between air pollution and COVID-19 infections and mortality did not consider potential confounders during the correlation analysis. Therefore, more specific studies need to be performed focusing on some additional confounders such as individual age, population density, and pre-existing comorbidities to determine the impact of air pollution on COVID-19 infections and deaths.

暴露于空气污染和 COVID-19 严重性:对当前见解、管理和挑战的回顾

几项流行病学研究表明,空气污染与呼吸道感染之间存在联系。2019 年冠状病毒病 (COVID-19) 的爆发对全球公共卫生构成了巨大威胁。然而,就流行和死亡而言,全球某些地区受到的影响比其他地区更严重。这种变化的原因和条件还有待探索。尽管一些研究表明空气污染与 COVID-19 严重程度之间可能存在相关性,但仍然没有足够的数据来给出有意义的答案。本综述总结了空气污染对 COVID-19 感染和严重程度的影响,并讨论了可能的管理策略和所涉及的挑战。该评价纳入了调查空气污染与 COVID-19 感染和死亡率之间相关性的现有文献。2.5和 NO 2,与 COVID-19 感染和死亡率呈正相关。一些数据表明,空气污染可以在 SARS-CoV-2 的空气传播中发挥重要作用。据报道,在患者需要住院的污染最严重的地区,COVID-19 的发病率很高。现有数据还表明,短期和长期的空气污染都可能提高 COVID-19 的严重性。然而,大多数表明空气污染与 COVID-19 感染和死亡率之间存在联系的研究在相关性分析中并未考虑潜在的混杂因素。因此,需要进行更具体的研究,重点关注一些额外的混杂因素,如个体年龄、人口密度和先前存在的合并症,以确定空气污染对 COVID-19 感染和死亡的影响。2021 年整合环境评估管理;17:1114–1122。© 2021 SETAC
