A study from one of America’s most polluted cities found that dirty air contributes to COVID-19 severity. The researchers who studied 2,038 hospitalized adults with COVID-19 in the Detroit area found those who needed intensive care and machines to help them breathe were more expected to live in neighborhoods with higher levels of air pollution and lead paint.
The worse the local air contamination, the higher the odds of needing intensive care and mechanical ventilation.
Long-term exposure to air pollution may damage the immune system and make it more vulnerable to viral infections, while fine particles in air pollution may also act as a carrier for the virus and help it spread, said Dr. Anita Shallal of Detroit’s Henry Ford Hospital.
The study “calls attention to the systemic inequalities that may have led to the stark differences in COVID-19 outcomes along racial and ethnic lines,” Shallal said in a statement from the European Congress of Clinical Microbiology and Infectious Diseases, where she presented the findings on Friday. “Communities of color are more likely to be located in areas closer to industrial pollution, and to work in businesses that expose them to air pollution.”
