Covid-19 Update

Baroness Noakes Excerpts

Thursday 12th November 2020 Lords Chamber

[Lord Bethell (Con)]

I thank the noble Lord for his characteristically detailed and forensic question. The lateral flow test, as I am sure he knows, has the terrific advantage of giving very few false positives, but we do not pretend that it gives a clinical-level analysis of all the negatives. We therefore do not use it in a clinical setting as a symptomatic test; we use it as a screening test for asymptomatic cases. That is why it has been so valuable in a mass testing environment such as Liverpool. We can back up the tests of those who are positive with a double test, either with another lateral flow test or with a PCR test, to ensure that we do not create a problem with too many false positives. We are working on the protocols now to figure out exactly what kind of rate of second testing we need to get a fair analysis.

The noble Lord is entirely right that the vaccine will be a game-changer, but not everyone will take it immediately and we are not sure how long each vaccine will last for, so there will be a role for testing even after the vaccine has been deployed. In the meantime, testing is very much focused on social care, clinical workers, schools and universities. Those are the four areas where we are focused at the moment, but we hope it can be used further to enable the opening of the economy, as he alluded to.

[Baroness Noakes (Con) [V]]

My Lords, there have been estimates that hospital-acquired Covid infections are as high as one-quarter of all hospitalised Covid patients, which seems pretty shameful and is likely to be a major contributor to the Covid death statistics. What do the Government currently estimate the impact of hospital-acquired Covid infections to be, and what action are they taking to deal with it?

[Lord Bethell (Con)]

My noble friend is entirely right; in any epidemic, nosocomial infection is one of the greatest challenges faced. If you want to find a recent infection of Covid, the best place to find it is where there is someone already with the disease, because that is the way that epidemics work. Hospitals necessarily have a high concentration of those with the disease. It is true that during the early months of the epidemic, when there were challenges with PPE and when practices within hospitals were not as disciplined as we would have liked, nosocomial infection, as it often is in epidemics around the world and throughout history, was a big challenge in hospital care and social care. That has been extremely well documented. However, I pay tribute to colleagues in the NHS who have come a very long way in the administration of PPE, confinement practices and infection control. The nosocomial infection that we are seeing is at dramatically lower rates than it was in the past, and that is due to the hard work and science of those in the healthcare sector.
