> The preponderance of evidence indicates that mask wearing reduces the transmissibility per contact by reducing transmission of infected droplets in both laboratory and clinical contexts. [1] When the primary vector of spread is through water droplets expelled while talking, coughing, or sneezing, I would think the importance of reducing the travel distance of those droplets would be self evident.
