But most people have stopped doing that because the consensus is you can't get it from touching mail or packages.
Would it be too much to ask for a link to something supporting this conclusion?
My own opinion, completely unsupported by any evidence, is that a lot of people never did it in the first place, or if they did, they quit after a while because it was too big a hassle. My further opinion, also unsupported by any evidence, is that most people are not checking the WHO website every day to see if there are any changes to their guidance on handling the mail, and then comparing it to the guidance from the CDC and other experts, to determine if there is a developing consensus on what to do with tomorrow's mail. I suspect most people go to sleep dead tired at night having left things undone, and don't have time to keep up with this stuff. I am not endorsing that, just expressing my opinion about what is going on in the real world.
As a side note, why do you believe any of this stuff about germs on surface transmission? Have you vetted all the scientists? They could be radical left wing climate change scientists moonlighting at the COVID related grant gravy train.
