Coronavirus loses most of its ability to infect shortly after being exhaled and is less likely to be contagious at longer distances, a study from the University of Bristol’s Aerosol Research Centre showed.

Researchers found that the virus loses 90% of its contagion capacity 20 minutes after becoming airborne and that most of that loss happens in the first five minutes of it reaching the air, according to the study, that simulates how the virus behaves after exhaling.
