Transmission risk

Caption

A new study looks at how airflow patterns inside the passenger cabin of a car might affect the transmission of SARS-CoV-2 and other airborne pathogens. Using computer simulations, the study looked at the risk of aerosol particles being shared between a driver and a passenger in different window configurations. Redder shades indicate more particles. Risk was shown to be higher with windows closed (top left), and decreasing with each window opened. The best case was having all windows open (bottom right).
