As of June 25, 2020, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes the coronavirus disease 2019 (COVID-19) has infected 9,535,219 people across 216 countries, of which 485,187 have died and 5,180,287 have recovered. Being the largest pandemic of the modern world,[1] it has brought the world to a standstill and provoked the scientific community to develop ways and means to combat COVID-19.[2] As a result, as many as 25,957; 6,640,000,000; and 1,190,000 articles or search hits are available as on June 21, 2020, for “COVID-19” on PubMed,[3] in Google's search engine,[4] and Google Scholar,[5] respectively.

The various articles published on COVID-19 have covered multiple aspects of this disease, including its environmental/economic/social effects, molecular diagnostics,[6] RNA sequence of SARS-CoV-2, treatment schedule,[7],[8] drug repurposing,[9] ongoing trials,[10],[11] failure of specific medicines and vaccines against COVID-19, and finally, the correlation between COVID-19 and SARS and/or Middle East respiratory syndrome (MERS). This suggests that the effects of COVID-19 are very widespread, perhaps even more than those of the World Wars.[12] However, a comprehensive article or book or series discussing all the above aspects of COVID-19 is the need of the hour. For example, in the article by Pande et al.,[12] the etiology, epidemiology, pathophysiology, diagnosis, prognosis, clinical symptoms and complications, and the current management strategies for COVID-19 have been described. However, information pertaining to the environmental aspects of COVID-19 is lacking in this and other similar reviews.[13] The clinical aspects of a pandemic or an endemic disease always have an intricate relation with the environment when the pathogen is environmentally modulated, as is the case with SARS-CoV-2. It has a crisscross relation with the environmental factors, especially the temperature and air. Therefore, its airborne transmission, although disproved, is still debatable.[14],[15] COVID-19 is undoubtedly nurturing and healing Mother Nature[15] via the imposed lockdowns.[16] However, it has also been aggravated in terms of the severity of symptoms in the infected patients via air pollution (AP), one of the key environmental components.[16],[17] These intricacies have not been addressed in any of the clinical reviews that cover every other aspect of COVID-19.[13] Inclusion of this information would make the reviews more comprehensive.

Many countries had witnessed heavy AP, especially high levels of carbon dioxide and nitrogen dioxide (NO2) emissions and a high load of particulate matter (PM) during the pre-COVID-19 period. However, as a result of the lockdowns, several countries have experienced a reduction in fossil fuel combustion, thus becoming free from the clutches of AP. Nevertheless, the rate of infection and severity of the disease were found to be more in places where the AP was higher,[17] thus highlighting the association between AP and COVID-19. AP causes lung diseases such as the common cold; cough; sneezing; and breathing issues including bronchitis, asthma, and many other respiratory syndromes. COVID-19 also causes similar clinical symptoms and is primarily a respiratory disorder. This could probably be the reason for the intricate relationship between COVID-19 and AP.[18]

The molecular events leading to an AP-induced increase in the severity of COVID-19 have been extensively studied.[16],[17] Experimental approaches indicate that aerosols and PM, two of the important air pollutants, can carry SARS-CoV-2 with them for a certain period of time, but airborne transmission of the virus has not yet been reported. Moreover, the angiotensin-converting enzyme 2 (ACE2), which acts as the receptor for SARS-CoV-2 and is present primarily on the surface of the human respiratory epithelial cells, gets upregulated in the presence of NO2 emissions and PM2.5. Similar situations were also reported during the SARS and MERS epidemics. Therefore, a higher expression of ACE2 in the respiratory epithelial cells could be one of the potential reasons for the high severity of COVID-19 in places with increased AP. Hence, all the nations where the number of confirmed cases of COVID-19 is unexpectedly high could consider correlating the number of cases with the degree of AP. Moreover, if a positive correlation is observed between them, environmental interventions could help to reduce the risk of COVID-19. In conclusion, articles on COVID-19 should also highlight the impact of the environmental factors on the spread of the disease, as shown in [Figure 1].
