[Newsphopick=Gyubin Lee] Without a mask, droplets produced during coughing can travel up to 12 feet. With a mask, this distance is reduced to just a few inches. Without a mask, droplets produced during coughing can travel up to 12 feet (3.7 meters), the visualization revealed, but with a mask, this distance is reduced to just a few inches in the best cases.
A dramatic new visualization shows exactly why it's a good idea to wear a face mask to prevent the spread of the new coronavirus. The simulation, which was described today (June 30) in the journal Physics of Fluids, also reveals that some cloth masks work better than others at stopping the spread of potentially infectious droplets.
"The visuals used in our study can help convey to the general public the rationale behind social-distancing guidelines and recommendations for using face masks," study lead author Siddhartha Verma, an assistant professor at Florida Atlantic University's College of Engineering and Computer Science, said in a statement.
