Professor Philip Nolan:

It is the same answer, I am afraid, on that one.

I want to make a quick comment on face masks and testing and tracing. They are really important parts of the strategy. What worries me a little is the narrative that they can replace other elements of the strategy. It has been suggested that if only we had testing and tracing in a couple of hours and everybody wore face masks, we could do all the things we used to do. Unfortunately, that is not the case. The evidence remains that reducing contacts, being very careful with handwashing and maintaining some distance, simply not being as intimate as we used to be in our normal ways of going about business, are essential.
