COVID-19 on Air Quality Index (AQI): A Necessary Evil?

, 2020
The disastrous effect of novel coronavirus has become a matter of concern for human health since December 2019. To counteract the spread of the disease, the many countries’ governments-imposed movement restrictions in different approaches. Retarding growth in various sectors had turned out to be a negative repercussion of the imposed lockdown.
