Face Shields No Match for Sneeze Vortex Rings

Do face shields provide enough protection to the wearers against COVID-19 if they don’t also wear a mask? No. But researchers in Japan are working to create face shields safe enough to be worn alone. In Physics of Fluids, Fujio Akagi and colleagues describe their work to gain a better understanding of what happens to the airflow around a face shield when someone nearby sneezes.

Face Mask Construction, Materials Matter for Containing Coughing, Sneezing Droplets

While the use of face masks in public has been widely recommended by health officials during the current COVID-19 pandemic, there are relatively few specific guidelines pertaining to mask materials and designs. A study in Physics of Fluids looks to better understand which types are best for controlling respiratory droplets that could contain viruses. The team experimented with different choices in material and design to determine how well face masks block droplets as they exit the mouth.
