As I have just said to Richard Leonard, the expert-driven nosocomial review group is examining that issue, and I hope that it will give us recommendations on it quickly. When it does, we will implement those recommendations.

It is right and proper, in my view, that we continue to take clinical advice about testing, for two reasons. First, as any clinician will tell you, there has to be a purpose to the tests that are carried out on people from an ethical point of view. Secondly—I have made this point repeatedly—while we still have concerns about what I stress is the relative reliability of the test for asymptomatic people, we do not want inadvertently to suggest that testing is the only thing that needs to be done to reduce the risk of transmission of the virus. That is particularly true in hospitals. With all infections, not just Covid-19, infection prevention and control measures are most important. They are taken extremely seriously by all health boards and in all hospitals.

The last point that I make to Alison Johnstone is the same, I think, as the last point that I made to Richard Leonard regarding the unvalidated statistics that have been reported about the possibility of hospital-acquired infection. We do not yet know whether those infections were acquired in hospitals—although I expect that there will be hospital-acquired infection—but it is really important that we recognise that that information has not been validated. Because of the incubation periods associated with the virus, some of the infections could have been acquired in the community. Let us be very careful when we are talking about these things so that we are dealing in facts, not in supposition. That is particularly important given the severity of the topic.
