Reduce the risk of Covid-19 transmission in a vehicle

A new study of airflow patterns inside a car’s passenger cabin has offered suggestions that will potentially reduce the risk of Covid-19 transmission while sharing rides with others.

A team of Brown University researchers used computer models to simulate the airflow inside a compact car with various combinations of windows open or closed. Results showed that opening windows created airflow patterns that dramatically reduced the concentration of airborne particles exchanged between a driver and a single passenger.
