Summary
Air pollution, including carbon monoxide (CO), nitrogen oxides (NOx), ozone (O3), and particulate matter (PM10), is linked to higher COVID-19 cases and deaths in Mexico City. The cold-dry season showed the most significant impact.
Area of Science:
- Environmental Science
- Epidemiology
- Public Health
Background:
- Air pollution is a significant environmental concern in urban areas.
- COVID-19 has had a profound impact on global public health.
Purpose of the Study:
- To analyze the association between atmospheric pollutant concentrations and COVID-19 epidemiological indicators.
- To investigate these associations within the Metropolitan Valley of Mexico (ZMVM).
Main Methods:
- An ecological epidemiological study design was employed.
- Poisson regression models for count data and random-effects models for continuous data were used.
- Data spanned from February 28, 2020, to June 30, 2021, with pollutant exposure stratified by season.
Main Results:
- Carbon monoxide (CO), nitrogen oxides (NOx), ozone (O3), and particulate matter (PM10) showed significant associations with COVID-19 morbidity and mortality indicators.
- During the cold-dry season, CO and NOx affected daily confirmed cases and daily deaths.
- PM10 was associated with daily confirmed cases, daily incidence, hospitalization rates, and fatality rates.
Conclusions:
- A clear association exists between COVID-19 epidemiological trends and exposure to CO, NOx, O3, and PM10.
- The impact of these pollutants on COVID-19 was more pronounced during the cold-dry season in the ZMVM.
