This experience tells us that if you embark on a screening programme without having carefully evaluated it first, without proper quality assured pathway, without certainty of test performance in field settings, without full information for participants, and without the means to..
ensure intervention needed for those with positive results does indeed take place, then you will end up with an expensive mess causing more harm than good.
From what I can tell current proposals for screening City of Liverpool with SARS-CoV-2 rapid tests are not fit for purpose

1) It is called a ‘pilot’ yet there appears to be no research design.

...many people will be given false results.
5) Harm from false results includes unnecessary isolation (for false positives), and false reassurance with potentially riskier behavior (for false negatives).

that the proposed Liverpool screening will fail to realise any benefit, and will cause harm through diversion of resources. It will distract from solving the problems with the test and trace programme.
