A University of Minnesota study looks at how COVID-19 is being distributed indoors

A new study by researchers at the University of Minnesota College of Science and Engineering shows how the coronavirus moves indoors.

The research team modeled the transmission of COVID-19 through aerosols that are expelled from the mouth when people talk and breathe. The team models the flow in three different settings: classrooms, elevators and a supermarket.

In the classroom setting, for example, researchers studied individual learning without asymptomatic treatment in front of the room for 50 minutes. They found that only 10 percent of the virus particles were filtered with good ventilation, but found that it mattered where the air vent was placed. When the teacher spoke directly below him, the aerosols did not spread so much.

According to researchers, this can help arrange classrooms and businesses with fewer “hot spots” or areas where aerosols collect.

“Once our work is over, I think more people will ask for help, because I think a lot of businesses that are reopening will have that need – movie theaters, drama theaters, all kinds of big gatherings,” said Suo Yang. , one of the researchers of the study in a press release. “If you do a good job, if you have good ventilation in the right place, and if you scatter the audience places properly, it can be much safer.”

Researchers are also working with the Minnesota Orchestra to see how aerosols travel when instruments are played on stage, and hope this study will be completed in August.
