Thanks for the study. From 2009. Some of us learned this back during the Avian Flu scare. Along with how a virus is transmitted, etc. At this stage of the game it seems that the stage is pretty well set with the masks on one side and the no-masks on the other.
Thankfully for most of us, the play is mostly over, except for the governors droning on and on.
