Covid-19 Update

Lord Willis of Knaresborough Excerpts

Thursday 12th November 2020 Lords Chamber

[Lord Bethell (Con)]

My Lords, the capacity that we have in track and trace is growing dramatically; the number of tests we have taken is going up. It is true that testing demand does fluctuate. There was a moment when universities had a very large outbreak and there was a huge amount of demand from universities, and there may well be other reasons why testing demand goes up in the future. But I reassure the noble Lord that the capacity, speed and accuracy of testing in this country are making huge progress on a day-by-day basis, and I pay tribute to those involved in the project.

[Lord Willis of Knaresborough (LD) [V]]

My Lords, a key factor in controlling Covid-19, with or without a vaccine, is test, trace and isolation, and I fully support that. Yet the recent survey indicated that some 20% of those asked to isolate actually failed to do so, rendering the system far less effective than it should be. What is the reasoning behind the reluctance of the Government to move from PCR to lateral flow testing for the test and trace programme, following the extensive clinical evaluations by PHE and Oxford University, which found 99.6% accuracy, including on the key criterion for track and trace of detecting asymptomatic carriers? Surely, accurate 48-hour testing would enable virus-free contacts to return to normal activity quickly, rather than sitting at home for 14 days.

[Lord Bethell (Con)]

My Lords, the noble Lord is entirely right on two things, and wrong on another. He is entirely right that isolation is absolutely key—without isolation, there is no point in testing or tracing. It is true that not everyone who is asked to isolate does isolate, but we have a programme in place to try to encourage, inform and inspire people to isolate. He is entirely right that lateral flow tests offer huge advantages, in terms of the speed at which they can be used, their cost and their flexibility. But we have bought tens of millions, maybe even hundreds of millions, of these tests in recent weeks. We are deploying them in mass testing, and we have completely followed the advice and inspiration of the noble Lord in this matter in a massive way.
