Air pollution is the
most significant environmental risk factor for all-cause mortality, and it has
caused substantial disability-adjusted life-years and economic loss. If you
realise that exposure to air pollution will increase the risk of diseases of
the respiratory system – and the COVID-19 is mainly a disease of the
respiratory system – you will realise that we are increasing the
susceptibility, the vulnerability of people who are exposed to air pollution.
Long-term exposure to air pollution has been linked to an increased risk of
dying from COVID-19 and, for the first time, a study has estimated the
proportion of deaths from the coronavirus that could be attributed to the
exacerbating effects of air pollution for every country in the world.
