Scientists from the University of Bristol have made a major breakthrough in understanding how certain viruses, including SARS-CoV-2, spread through the air. The findings show that carbon dioxide (CO2) levels play a critical role in the lifespan and transmission of airborne viruses.

CO2 increases the lifespan of the virus

Viruses are known to spread through small droplets that are released when you breathe, sneeze or cough. These droplets transmit viruses from one person to another through the air. However, recent research is investigating how the chemical composition of the droplets affects the lifespan of the virus. (Sanjana Gajbhiye, more at earth.com)
