People Exposed To Air Pollution Are Less Immune To COVID-19

Even after the pandemic, scientists are continuing their research against COVID-19 to their extreme potential. Recent research shows that people who are exposed to higher levels of air pollution may have greater chances of being diagnosed with COVID-19 than others.

This research was conducted in places having more air pollution pre-pandemic. As it allowed researchers to compare the chances of being affected with COVID-19 in such places than ever-green areas. The majority of data showed the experiment positive. Possibly, the air pollution favored transmission of COVID-19 in people or made the immune system less susceptible to diseases.

People Exposed To Air Pollution Are Less Immune To COVID-19

Manolis Kogevinas, a researcher from ISGlobal said that “The problem is that previous studies were based on reported cases, which had been diagnosed, but missed all the asymptomatic or undiagnosed cases.” Different scenarios are been testified before concluding anything.

Basically, during the initial stage of research, two groups were divided. People who had spent more time in places with a high level of air pollution and people with less exposure to the same.

Less Air Pollution During COVID-19

The scientists measured a series of virus-specific antibodies with more and less exposure to air pollutants. To be more specific NO2, PM2.5, black carbon, and ozone.

“This is the first study to perform mass screening of SARS-CoV-2 specific antibodies in an adult cohort to examine the association between their residential exposure to air pollution before the pandemic, SARS-CoV-2 infection, and disease,” was a comment given by Cathryn Tonne.

Apparently, the test size of participants been involved in the experiment was 9,605 people. Out of which only 5% showed positive results against the hypothesis. This was solely for the purpose to understand if air pollution was in fact an element affecting humans against COVID-19. At the initial stage IgM, IgA, and IgG antibodies were found in almost 4000 participants, but no one had any traces of infection relating to COVID.

Out of these 4000 participants, 18% may have shown some early signs of virus-specific antibodies generated in their body on its own. This study helped scientists realize the body reacting to various habitats, in this situation air pollution. In order to see our body’s extreme response against infections and diseases, the PM 2.5 levels were measured.

Rafael de CID from IGTP said that “The combination of individual genetic risks that we have previously identified in COVICAT individuals and this new data on environmental impact caused by air pollution exposure will contribute to understanding the complex interplay and mechanisms underlying the severity of COVID-19.”

The initial approach for this study was to understand what risks can be eliminated by reducing air pollution. In recent times, after the pandemic, a huge downtrend could be seen in pollution levels around the world. But looks like the world is coming back on track of not taking any precautionary measures against reducing air pollution.

Eventually, this study was published in Environment Health Perspectives Journal. Further information is yet to be revealed as scientists are conducting more experiments relating to health aspects against air pollution. We recommend every city to look at their precautions against this increasing air pollution.

It may not just help them avoid COVID-19, but also keep young life active. Making teens immune to various respiratory diseases could be approached by adopting less environmental pollution exposure.
