The National Institute of Health and University of Pennsylvania show in a demonstration with laser light-scattering how a mask can help someone prevent the spread the new coronavirus. Droplets that can harbor infectious particles are released when someone speaks. The laser light-scattering helped to visualize these particles as someone spoke (with increasing volume), with and without a mask. Scientists involved in the study noted that the amount of droplets produced while coughing were similar to the amount produced while speaking.
