A new nationwide study conducted by researchers at Harvard University ’ s T.H .
Chan School of Public Health is the first to show a statistical link between long-term exposure to pollution and COVID-19 death rates.1 The study , which has yet to be peer-reviewed , shows that coronavirus patients living in areas that had high levels of air pollution before the pandemic are more likely to die from the infection than patients living in parts of the country with less air pollution.1 In the analysis , data was collected for approximately 3,000 counties in the United States ( 98 @ @ @ @ @ @ @ Apr .
4 , 2020 .
The study revealed that higher levels of tiny , dangerous particles in air known as PM were associated with higher death rates from the COVID-19 infection .
PM is believed to be one of the world ’ s most dangerous air pollutants .
It is made up of tiny particles ( smaller than 2.5 micrometers ) that can seep into human lungs and bloodstreams.2 The source of PM is usually automobile exhaust and power plants , as well as toxic fine particle air pollution from burning wood @ @ @ @ @ @ @ high levels of PM to heart disease , chronic bronchitis and other respiratory illnesses .
It has been estimated that PM contributed to 4.2 million deaths worldwide in 2015 alone.2 The Harvard study reveals that even an increase in one microgram per cubic meter of air could potentially increase COVID-19 deaths by 15 percent even accounting for factors like smoking rates and population density.1 For example , the study found that an individual living in a county for decades with high levels of PM is 15 percent more likely to die from the @ @ @ @ @ @ @ one unit less of the fine particulate pollution.3 According to Francesca Dominici , PhD , a professor of biostatistics at Harvard University and a principal investigator on the study , “ This study provides evidence that counties that have more polluted air will experience higher risks of death for COVID-19.
” 3 The results of this study also underscore the importance of continuing to enforce existing air pollution regulations during the COVID-19 crisis .
Based on our result , we anticipate a failure to do so can potentially increase the COVID-19 death toll @ @ @ @ @ @ @ system and drawing resources away from COVID-19 patients.1
