Recent reports highlight that the transparent partitions installed to combat the spread of COVID-19 may actually do more harm than good. As the world attempts to adapt to life amid ongoing health challenges, many institutions are implementing these barriers in hopes of curbing transmission, particularly with the Delta variant on the rise. However, research indicates that these barriers can disrupt proper airflow.
Experts studying aerosols and ventilation have found that these plastic dividers may not provide the protection people assume they do. In fact, they can create a false sense of security, and at times, they might even exacerbate the problem. The New York Times notes that these barriers can redirect germs towards other individuals in the vicinity, including employees and customers.
In spaces without barriers, respiratory particles are typically diluted by fresh air every 15 to 30 minutes. Introducing barriers alters the airflow, leading to areas known as ‘dead zones,’ where harmful particles can accumulate. Linsey Marr, a civil and environmental engineering professor at Virginia Tech, explains that having numerous barriers in a classroom can significantly hinder ventilation, trapping aerosols and heightening the risk of spread beyond individual desks.
While these barriers may effectively block larger droplets from sneezes or coughs, COVID-19 predominantly spreads through smaller, less visible aerosol particles. Studies from Johns Hopkins and various research in the UK reveal alarming findings. For instance, classroom desk screens have been linked to increased infection risks, and barriers with sidewalls in offices can obstruct airflow. Furthermore, a study examining schools in Georgia concluded that desk dividers had minimal impact compared to improvements in ventilation and mask-wearing.
One particularly concerning study from 2014 indicated that cubicle dividers may have contributed to a tuberculosis outbreak in Australia. Another British study demonstrated that while barriers might catch larger particles from a cough, they do little to contain smaller particles released during speech, allowing them to circulate in the air and still pose a risk.

In summary, while the intention behind using plastic barriers is to reduce the transmission of COVID-19, recent studies suggest they may inadvertently hinder ventilation and increase infection risks. As organizations reassess their safety measures, the emphasis should be on improving airflow and utilizing effective protective strategies.
