No but I'll tell you, In Taiwan they will check your temperature whenever you go into a restaurant/Tea house, grocery store or mall. If you pass you get in. If you don't, You stay outside for a few minutes and they try again. It's amazing to me as to why we can't do that here.
It's really scary because we really don't know when this is going to end. I guarantee you we'll lose someone well known soon too.
Well allegedly people are most contagious before they even show symptoms, so I doubt that would help anything. Also, who feeds the people who don’t pass the “temp test” after they are kicked out of the grocery store?
You can't say that it won't help anything. You can say that a lot will get through but it will certainly catch some.
