Commence the insults, but.
Facts known by the medical profession and, hopefully by the politicians.
Pillar 2 testing has an inbuilt false positive rate of 0.8 %.
Not a lot, pretty good for any testing regime.
200.000 people tested 2000 come back as positive of these 1600 are known false positives.
IF and it is a very big IF, all 2000 are contacted and told to self isolate it appears only 18% will comply.
1,640 per 200.000 tested per day out and about in society.
11,480 per week, most of these "asymtomatic" or false positives.
However, as for as I can tell the app will flag up contact with these people, pub,shop, restaurant, etc.
Thus multiplying the figure by a factor not yet known (take up of the app and accuracy of same).
As the 0.8 is not in debate I would ask the question, what is the agenda?
