The estimation results indicate that a 1 percent increase in long-term exposure to particulate matter 2.5 leads to an increase in COVID-19 deaths by 5.7 percentage points and an increase in the COVID-19 fatality rate by 0.027 percentage point, but this exposure is not necessarily correlated with COVID-19 cases. People with underlying health conditions such as respiratory illness caused by exposure to air pollution might have a higher risk of death following SARS-CoV-2 infection. This finding might also apply to other countries where high levels of air pollution are a critical issue for development and public health.CC BY 3.0 IGOCORONAVIRUSCOVID-19PANDEMIC IMPACTAMBIENT AIR POLLUTIONINSTRUMENTAL VARIABLESTHERMAL INVERSIONPARTICULATE MATTERWorking PaperWorld Bankhttps://doi.org/10.1596/1813-9450-9543
