Problems with test false positive rate during periods of low prevalence and hitting the BBC since the children are the victims. The government will be unable to duck and dive this time, since the parents realise their kids are being victimised due to test false positive rates . They don't know we've been hopping mad about this for a year, while they've been thumb in bum mind in neutral using up their Furlough money and guzzling cheap chardonnay, well they are not so laid back now!
The Royal Statistical Society believes more of the positive results produced this week could be wrong than right. Some parents are so number blind, they still insist "I support the idea of testing ..."

As it's sprayed all over the BBC, there's a chance these emotional stories about children might bring a Casedemic in schools to light, if it's real. And I hope people might put 2 and together about real case numbers.Anyway it'll keep Gavin Williamson busy.

Worth noting this is LFD related as opposed to PCR.

As a side note, so far this week the majority of tests in England have been LFD...

Basic maths, assuming an OFPR of 0.34%.
If an average school has 500 people and pupils are tested 3 times a week thats 1500 tests a week.
Even assuming 0% prevalence that's 5 pupils a week false positive.

Now assume each bubble as 10 or so people in it, thats up to 50 or so pupils and staff (and contacts) isolating without reason every week....

The switch to LFD without PCR for in-school results is going to cause huge issues.

PCR has severe issues but LFD is potentially worse due to the scale its rolled out.

Im fully expecting a pseudo increase in "cases" due to schools going back.

Ultimately, at the current low levels of SARs2 in the community the lack of accuracy of the tests is a major, major issue. Especially as we now seem focussed solely on cases as people aren't dying any more.

Well, well! Has the worm turned? How does this serve the government?
I just sent them the following question for them to ignore at their leisure:
What sources show that LFT tests produce more false positives than the PCR tests used for covid-19 throughout the pandemic?
