Or one might say it is an example of Duning Kruger. A person thinks he has it figured out because he can see the cloth masks don't stop all expired respiratory gases.
What, are we stupid? No one looked at that?
I repeat for some reason I'm not at all clear, the studies have looked at the transmission of the virus is actual situations. If both the infected person and the uninfected person have simple cloth masks, the infection rate is reduced by at least 85%. Both people need to be wearing masks because people are contagious before they know they have the infection.
The outbreak within the WH and surroundings is evidence that relying on less than accurate rapid tests was a big incompetent mistake. Trump has gone from "I don't need a mask because people around me have been tested" to a ridiculous (paraphrased) "I took one for the team".
