New York: Increased level of pollution can have detrimental effects on people affected by SARS-CoV-2, the virus that causes Covid-19, revealed a review of multiple studies.
Exposure to every small (1 gram per cubic meter) increase in long-term fine inhalable particle (PM2.5) was related to an 8 percent increase in mortality during the pandemic, said researchers within the commentary, published online within the journal Annals of the American Thoracic Society.
The team, led by Stephen Andrew Mein, from the Department of drugs at Beth Israel Deaconess Medical Centre in Boston, US, examined published research that discussed whether pollution could also be linked to worse Covid-19 outcomes, also the connection between pollution, respiratory viruses, and health disparities.
They found that pollution contributed to fifteen percent of Covid-19 mortality worldwide.
Similar findings by researchers at the Harvard University also noted that even alittle increase in long-term exposure to PM2.5, or particulate with a diameter of two .5 micrometers or less, can cause an outsized increase within the death rate from Covid-19.
While the precise mechanisms aren't fully known, scientists suggest that long-term exposure to pollution may impair the system , resulting in both increased susceptibility to viruses and more severe viral infections.
