Bluetooth
Of all the fancy-dan things on my phone, bluetooth is probably the least reliable!
Anyone remember those radio-controlled cars you might have had as a kid? I went to a Radio Controlled Car themed birthday party aged about 12 in someone's back garden. About 20 of us trying to race our cars, all working off similar radio frequencies... absolute chaos, cars everywhere.... my car won because it was so old that it had an actual wire connecting the car to the controller, thus didn't use radio!
This is rather an alarming statement from TheGump's link posted above...
If the NHS later discovers that your diagnosis was wrong (and your reported symptoms are not coronavirus), the other users will receive another alert, letting them know if they can stop self-isolating.
Which would seem to indicate that the NHS are not exactly awash with confidence over test results...!
We could start with the majority of BBC presenters/reporters.
And no, I shan't be downloading the app. I don't usually run with my phone and most of the time it sits in my car. I'm certainly not going to put myself in the position where I have to self isolate for 14 days due to a notification that my phone might have been in close contact with a carrier that has walked past my car!
Visibility good except in Hill Fog
Understood... which is why i said it would "seem" to indicate that there is a margin for error there... perhaps i should have said in testing OR diagnosis. I mentioned unreliable testing as i have a distant family member who sadly passed away, who was tested negative in hospital for Corona, but the doctors said no it is definitely Corona.... it now turns out it may not have been Corona after all and a series of mistakes were made with regard to several elements of his testing/diagnosis/treatment, but i'd rather not go too far into that...
In a way that is similarly, if not more, alarming, if we are expecting unqualified members of public to report themselves as having Corona symptoms, and then asking everybody they have been in contact with to isolate themselves based on their say so...
I cannot find it now, but I can remember commenting to my partner about a report on NHS staff who were self isolating as they thought they had, or might have, Covid. When tested, only a tiny proportion actually had it, less than 20%. I know some tests have a significant false negative rate, but even so. And if you look at the overall number of tests, and the number of cases, the same applies. Most who are tested have not got it.

As she says at the end:
“Fifty per cent of the people I speak to think they have had Covid-19. This is a cautionary tale.”
