COVID-19 Study: School ventilation system may play a role in preventing coronovirus spread


MINNEAPOLIS – As more schools in the US choose to reopen or learn online in the midst of the COVID-19 epidemic, a new simulation shows how coronavirus can spread in the classroom and what you can do to prevent it.

Researchers at the University of Minnesota, which is studying the spread of coronaviruses, focused on ventilation units, desks and placements of people.

He performed two mock classes. The first one had teachers directly under the ventilation system. The second showed the ventilation system at the back of the room.

The scenario assumes that the teacher is an asymptomatic carrier of COVID-19.

As the simulation begins, the particles move around the classroom, with the virus spreading far less in the classroom where the teacher is directly below the vent. Red areas indicated warm areas where the virus could be collected. In the simulation, the classroom where the teacher and vent were in the opposite direction all appeared red.

According to the study, the virus was heavily contained in the simulation where the teacher was standing under the vent.

Associate Professor Jiarong Hong of the University of Minnesota said, “What we found is actually the design of ventilation, especially the ventilation conditions in relation to individuals who make a huge difference.”

But there are two important caveats, the study assumes that the teacher, not the student, is infected. It also does not take into account what happens when you wear a mask.

“If we think about best practices like wearing masks, social disturbances, proper ventilation, but also having a classroom layout in relation to that ventilation, I think we have the best chance of reducing transmission, “Dr. John Brownstein, an epidemiologist and an ABC News contributor, reported good Morning America.

Dr. Anthony Fauci is also tapping eye protection as another possible tool to fight the virus.

“If you have goggles or eye shield, you should use it,” ABC News’s chief medical correspondent Drs., Spoke on ABC News’ Instagram Live, the nation’s top infectious disease specialist. Jennifer Ashton told.

He said that goggles and eye or face shields are “not universally recommended” at the moment, but if you really want to be full, you should probably use it.
