Air pollution aggravating COVID-19 lethality? Exploration in Asian cities using statistical models

Area of Science:

• Environmental Health
• Epidemiology
• Public Health

Background:

• The COVID-19 pandemic has caused significant global mortality.
• Air pollution is a widespread environmental exposure with known health impacts.

Purpose of the Study:

• To investigate the correlation between air pollution levels and COVID-19 mortality rates.
• To identify specific particulate matter (PM) sizes associated with increased COVID-19 lethality.

Main Methods:

• Statistical analysis of data from nine Asian cities.
• Utilized analysis of variance and regression models.
• Examined the relationship between Particulate Matter (PM10 and PM2.5) and COVID-19 mortality.

Main Results:

• A significant positive correlation was found between air pollution levels and COVID-19 lethality.
• Long-term exposure to PM2.5 showed a significant correlation with COVID-19 mortality per case (p < 0.05).
• PM10 exposure did not show a significant correlation with COVID-19 mortality per case (p = 0.118).

Conclusions:

• Air pollution is an elemental factor exacerbating COVID-19 mortality.
• High PM2.5 exposure is a significant risk factor for severe COVID-19 outcomes.
• Public health interventions should consider air quality in highly polluted areas.
