This study by Allen Haddrell, Henry Oswin, Mara Otero-Fernandez, Joshua F. Robinson, Tristan Cogan, Robert Alexander, Jamie F. S. Mann, Darryl Hill, Adam Finn, Andrew D. Davidson, and Jonathan P. Reid reveals how rising levels of CO2 not only enhance the aerosolability of SARS-CoV-2 but also significantly elevate the risk of COVID-19 transmission. Their findings emphasize the urgent need for improved indoor ventilation to combat viral spread.

Abstract

This study investigates the impact of ambient carbon dioxide (CO2) concentration on SARS-CoV-2 aerosolability and infection risk. The researchers found that a moderate increase in CO2 concentration significantly increases SARS-CoV-2 aerosolability, more so than changes in relative humidity. Modeling suggests this CO2 increase leads to a substantial rise in COVID-19 transmission risk. The findings highlight the importance of ventilation and low CO2 levels indoors to mitigate disease transmission and emphasize the need for further research on the effects of rising atmospheric CO2 levels.
