My Wife is one of the Supervisors (20+ years) of a large group of Medical labs who sees hundreds of patients each day. Their sanitation and testing procedures haven't changed because they are more than adequate as they are.
The Lab Techs don't wear masks themselves, rather, the patients are given a mask if they are coughing or sneezing so as to prevent the droplets from being spread. The Techs, because they are working directly in the patients face, only wear a mask if the patient (such as a child) has difficulty keeping the mask on or in place or has a condition that prevents him from wearing one.
There's a lot of silliness and misinformation out there. Yesterday at Home Depot, the cashier was wearing purple Nitrile gloves. I asked her why and she said it was because of the Contra virus. I told her that the virus doesn't bore through the skin rather it is spread by the hands to the mucous membranes of the eyes nose and mouth. The virus could be on the glove just as easily as on her hands.
She looked surprised and said "Well everyone else is wearing them so I figured I better wear them too".
The gloves gave her a false sense of security which could lead to her not washing her hands as regularly and or exposing her hands to the virus because she wasn't trained to take the gloves off properly.
I wonder if she'll run to Costco to get a crate of toilet paper after work.
