A small rise in people's long-term exposure to air pollution is associated with an 11% increase in deaths from Covid-19, research has found. Another recent study suggests that 15% of all Covid-19 deaths around the world are attributable to dirty air.

The available data only allows correlations to be established and further work is needed to confirm the connections, but the researchers said the evidence was now strong enough that levels of dirty air must be considered a key factor in handling coronavirus outbreaks.
