Question to the Department of Health and Social Care:

To ask Her Majesty's Government what assessment they have made of the effect of air quality on the exacerbation of COVID-19 symptoms.

There is no clear evidence yet to suggest that air pollution has a direct link to the spread or severity of COVID-19.

Public Health England and other Government departments are reviewing and considering factors such as air pollution which may influence the health impact of COVID-19. This includes assessing whether there is any evidence of an association between exposure of particulates and COVID-19 mortality in the United Kingdom. The Department for Environment, Food and Rural Affairs’ independent Air Quality Expert Group has launched a call for evidence to assess the impact of the pandemic on air quality issues.
