This theme cropped up in the comments sections of newspapers and elsewhere .
"Surely people need to know if someone living in their area has coronavirus"?
Armed with that knowledge what is it that these people would do that they should already be doing anyway?
It will be a big problem for society. No official record system to demonstrate you have had the virus and prove it. There will be people who've had it who can't prove, people who think they've had it and have and can't, those that think they've had the virus and haven't and those that think they haven't but have. There'll be the odd very rare person immune (most people have none whatsoever).
