“What does a mask do? Blocks respiratory droplets coming from your mouth and throat. Two simple demos: First, I sneezed, sang, talked & coughed toward an agar culture plate with or without a mask. Bacteria colonies show where droplets landed. A mask blocks virtually all of them.” -Dr. Richard Davis, Clinical Microbiology Lab Director, from sister organization, Providence Sacred Heart Medical Center in Spokane, Washington.
