abstract={The present study involves the investigation of air quality of Dhaka city, Bangladesh, before and during the periods of lockdown imposed to reduce the spread of a novel coronavirus (<i>COVID-19</i>) and comparison of data in corresponding periods of two previous years. Further, the consequences of <i>COVID-19</i> in terms of economic disruptions were also studied. The accelerated and vast diffusion of <i>COVID-19</i> in Dhaka has a high association with air pollution compared to the other cities of Bangladesh. Air pollution can be considered as an important determinant in the <i>COVID-19</i> crisis. It was found that the mean air quality index (AQI) in Dhaka before lockdown in March in 2020 was found to be 4.82% and 5.30% lower compared to the corresponding period in 2018 and 2019, respectively. On the other hand, the average AQI during the lockdown in 2020 was found to be 9.57% and 16.74% lower respectively compared to the same period in 2018 and 2019. A significant negative correlation was found between AQI and rainfall (p&lt;0.01) during the period of lockdown. Indeed, Dhaka city had better air quality during the lockdown but it was prognosticated that the remittance would fall by about 22% and GDP would plunge to a range between 2% and 3% in 2020 due to <i>COVID-19</i>.},
