A new study explains how coronavirus hinders a trip on the droplets released when you cough, sneeze, speak or speak and walk around the room.

University of Minnesota scientists hope their work will help schools and businesses take steps to reduce the chances of transmitting COVID-19 when they reopen.

In the study, they created a model of how these aerosols move through indoor spaces like rooms, elevators and supermarkets. They also compared the way the virus caused in different types of ventilation and with the distance between different people in a room.

Jiarong Hong, associate professor of mechanical engineering, said: "You see a lot of people talking about the risks of being in confined spaces, but no one gave a quantitative number."

"I think the main contribution we have made is to combine very precise measurements and simulate computational fluid dynamics to make quantitative estimates of risk," he said in a statement. Press of the university.

The researchers found that good ventilation can filter some viruses, but can leave it on the surface.

In a classroom, they run a simulation in which a teacher with no symptoms talks for 50 minutes continuously. It found that only 10% of aerosols are filtered out. Most particles remain on the walls.

"Because this is a very strong ventilation system, we think it will clear a lot of aerosols. But …
