Hace 4 días · CO2 increases virus lifespan. Viruses are known to spread through tiny droplets expelled when we breathe, sneeze, or cough. These droplets carry viruses from one person to another through the air. However, recent research explores how the chemical makeup of droplets influences the lifespan of a virus. Under normal circumstances, the fluid in ...

Hace 1 día · High pH drives the loss of viral infectivity in aerosols. Discussing the link between CO2 levels and infection risk, Dr. Allen Haddrell, senior research associate in aerosol science at the University of Bristol, said: “The high pH of exhaled droplets containing the SARS-CoV-2 virus is likely a major driver of the loss of infectiousness.
