Plastic shields, barriers for COVID-19 precaution not likely to help
Fox News
Plastic shields propped up in classrooms to reduce COVID-19 spread likely don’t offer much benefit, interrupting airflow and increase risk of exposure, according to a news report and emerging evidence.
Linsey Marr, professor of civil and environmental engineering at Virginia Tech, likened the phenomenon to cigarette smoke, telling the New York Times in part: "One way to think about plastic barriers is that they are good for blocking things like spitballs but ineffective for things like cigarette smoke...The smoke simply drifts around them…" Research published in the journal Science by Johns Hopkins indicated that desk shields increased the risk of COVID-19-related outcomes.More Related News
