I posted a lengthy account from an ER doctor this morning
Only a few of his staff have gotten the virus. He has treated over 500 patients. He said masks work.
I know a guy whose 91 year old aunt died of COVID in a nursing home.
She shared the room with her 94 year old husband. Despite sharing a room with a woman who died of COVID he did not become ill.
He did not even test positive.
And no, he was not wearing a mask.
Your doctor is full of shit.
The virus can enter through the eyes. A mask is not for the user’s protection.
A mask minimizes the dispersion of particles if the user sneezes/coughs.
Of course, that user is now walking around with an infected mask.
You can minimize the dispersion of particles by sneezing/coughing into your hands or elbow, like we were all taught as children. Wash your hands afterward and you are not walking around with a piece of cloth loaded with contagious material.
