High air pollution could be one of the most important factors in deaths from coronavirus disease. This is indicated by a new study that analyzes what happened in 66 administrative regions in Italy, Spain, France and Germany, and which concludes that 78.5% of deaths from this disease occurred in only five regions, precisely those with more polluted air.
This research examined the levels of nitrogen dioxide (NO2), a pollutant produced largely by diesel vehicles, as well as the climatic conditions of air dispersion in these areas, by using satellite images.
These results indicate that long-term exposure to high levels of NO2 may be one of the most important contributors to mortality caused by the COVID-19 virus in these regions and, perhaps worldwide, the study’s conclusions indicate.
However, the analysis shows an association but not a direct causal link. It is now necessary to examine whether the presence of an initial inflammatory condition is related to the immune system response to the coronavirus.
