The plastic barriers that shot up at sales counters and order windows across America during the COVID-19 pandemic may actually be facilitating the spread of the virus, not protecting people from it.
“If you have a forest of barriers in a classroom, it’s going to interfere with proper ventilation of that room,” Linsey Marr, professor of civil and environmental engineering at Virginia Tech, told the NYT. “Everybody’s aerosols are going to be trapped and stuck there and building up, and they will end up spreading beyond your own desk.”
A June study led by researchers from Johns Hopkins University found that plastic screens around desks in classrooms were correlated with increased transmission of COVID-19. Another study of a Massachusetts school district found that the barriers impeded air flow. Scientists say that under normal ventilation circumstances, exhaled virus particles are dispersed and replaced by fresh air every 15 to 30 minutes. With barriers in place that change air flow, dead zones can be created where the fresh air doesn’t travel and the virus particles concentrate.

It will be interesting to see if Dr. Zelenko’s as well as many other experts in the field of virology predictions will materialize and what the reaction will be?
"But we have to do something!!!"
Those plastic barriers combined with a mask make it harder to hear what is being said. People have to speak louder and when they do, more air is forced out of their lungs and more spittle is discharged into the air. Great job, captain obvious, for pointing this out through a study.
Once again another study that will be sidelined like the laytest mask study showing cotton cloth masks don’t work. They may delay the spread by five or so minutes but when you are in a room (e.g. school children) for hours upon hours, a five minute delay doesn’t mean squat. Cotton cloth masks are ineffective and never should they be worn or sold as such. Interesting note here those blue masks every one likes to buy and wear have a warning label that says will not prevent the spread of the Communist Chinese Flu.
Yet another reason to trust the CDC and Herr Fauci...NOT
Everything they have mandated has actually worked to spread the disease more and infect more people.
It’s like it was all intentional.
