This completely undermines the point of contact tracing.

The idea of the 14 day isolation is that contacts can take up to 14 days to show symptoms.
IF a negative test worked to assure us they won& #39;t, the guidance would make sense.

But the test is only 70% sensitive when done when people have Covid-19 and are unwell. When they haven& #39;t yet developed symptoms it will almost invariably be negative.

I called out some bad advice yesterday.

Extremely irresponsible.

No wonder @ChrisCEOHopson said in @BBCNewsnight delays in testing will cause problems. He& #39;s been led to believe there& #39;s a test that can rule out infection.
