A new study conducted by researchers at the T.H. of the University of Harvard Chan School of Public Health is the first to show a statistical link between long-term exposure to pollution and COVID-19 mortality rates. The study, which has yet to be peer reviewed, shows that coronavirus patients living in areas with pre-pandemic air pollution levels are more likely to die from the infection than patients living in parts of the country with less air pollution. In the analysis, data was collected for about 3,000 counties in the United States (98 percent of the population) until April 4, 2020. The study revealed that higher levels of tiny and dangerous particles in the air known as PM2.5 were associated with higher mortality rates for COVID-19 infection.
