How The Spread of COVID-19 May Correlate with Air Pollution

Last updated: 31st August 2021

New research suggests that there may be a possible link between the rate of spread of the coronavirus and areas with higher levels of air pollution.

A preliminary study by Italian scientists detected the coronavirus on particles of air pollution which many suggest that the virus could be transported over distances. However, this is just a preliminary study so it is still unknown if the coronavirus is able to cause disease through particulate matter.

Particulate matter (PM 2.5 and PM 10) are tiny solid particles and liquid droplets that can be very harmful to health with continued exposure at high volumes. They are produced in a variety of ways, such as fires, smoke stacks, and car exhausts. With PM 2.5, these particles are so small that they can get deep into our lungs and this can lead to respiratory and cardiovascular problems.

The Preliminary Study

Italy is known to have issues with air pollution and air quality, particularly in Northern Italy. In an annual report that showed air pollution figures for 2018, most of the highly affected cities were in Northern Italy.

The Italian scientists collected air samples from two sites in the Bergamo province in Northern Italy, one from an urban area and the other from an industrial area. The samples tested had found a gene that was specific to COVID-19 and this was detected by blind testing at an independent laboratory.

Statistical analysis by the research team suggests that higher levels of air pollution could correlate with higher infection rates of the coronavirus in Northern Italy.

The study was led by Leonardo Setti at the University of Bologna in Italy and whilst detections have been made, the study has not been peer reviewed and will need further investigations before a conclusion can be reached. However, experts to agree that this may be plausible.

Coughing and sneezing are the common forms of transmission of the virus. Whilst the larger fluid droplets might fall-off within a metre or two, the finer particles could travel much further and they may remain viable in the air for some time. It could be possible that the virus is carried through air pollution and particulate matter which could increase the rate of spread.
