A room, a bar and a classroom: how the coronavirus is spread through the air

The risk of contagion is highest in indoor spaces but can be reduced by applying all available measures to combat infection via aerosols. Here is an overview of the likelihood of infection in three everyday scenarios, based on the safety measures used and the length of exposure

To calculate the likelihood of transmission between people in “at-risk” situations, we used the Covid Airborne Transmission Estimator developed by a group of scientists led by Professor José Luis Jiménez from the University of Colorado. This tool is aimed at highlighting the importance of measures that hinder aerosol transmission. The calculation is not exhaustive nor does it cover all the innumerable variables that can affect transmission, but it serves to illustrate how the risk of contagion can be lowered by changing conditions we do have control over.
