How Can a Restaurant’s Airflow Patterns Affect Transmission Rates of Airborne Virus Particles?

Researchers from UC Davis and the University of Oregon have created a 3D model of how airflow in a restaurant dining room might influence the transmission of COVID-19 among patrons. The modeling was created in response to a recent study in China that analyzed a cluster of infections traced back to a restaurant in Guangzhou. These data suggest that reopening of restaurants, and other businesses where patrons may linger in the same location for extended periods, should take into account airflow and ventilation considerations.
