I only know of people being tested who clearly have the virus, one guy who was already a very sickly person so I'd be surprised if he pulls through. I don't know anyone who has been tested who hasn't put themselves forward.
I think basically we're told to stay inside, and generally people are sticking to that, but I only think this week it has dawned on people that it's quite serious, from what I've seen when I've gone out. People cross the road when you walk toward them now. OK, they might have done that with me anyway...
As I mentioned before, the NHS was strained even before this so I see the lack of testing as a serious oversight misjudged as a cost saving exercise. I keep hearing how widespread testing is "a week away", but it always seems to be next week. Right now there is this idea that we do fairly well of just kind of getting on with it, as much as you can either not working or wfh. BoJo knows that British people in general will bunker in. To me it's buying time if nothing else, and obviously that will affect the economy quite seriously.
