This study aims to explore the relationship between ambient NO 2 levels and the transmission ability (basic reproductive number, R 0 ) of COVID-19 in 63 Chinese cities. After adjustment for temperature and relative humidity, R 0 was positively associated with NO 2 concentration at city level. The temporal analysis within Hubei province indicated that all the 11 Hubei cities (except Xianning City) had significant positive correlations between NO 2 concentration (with 12-day time lag) and R 0 (r > 0.51, p < 0.005). Since the association between ambient NO 2 and R 0 indicated NO 2 may increase underlying risk of infection in the transmission process of COVID-19. In addition, NO 2 is also an indicator of traffic-related air pollution, the association between NO 2 and COVID-19′s spreadability suggest that reduced population movement may have reduced the spread of the SARS-CoV-2.
