Up to 15 of all COVID-19 deaths globally may be linked to long-term exposure to air pollution.br In addition, 18 of fatalities caused by the virus in the United States are linked to it as well.br This means that air pollution may have played a role in roughly 40,000 of the more than 220,000 deaths.br If both long-term exposure to air pollution and infection with the COVID-19 virus come together...br We have an additive adverse effect on health, particularly with respect to the heart and blood vessels.br This leads to greater vulnerability and less resilience to COVID-19, reports UPI.
