The right hon. Gentleman is spot on about what has been happening in schools. Sadly, in many cases we have seen a rise in demand for tests because people are, reasonably, unable to distinguish between the symptoms of covid and a seasonal cough or cold. We are trying to address the situation as fast as possible. The one consolation we have is that children are much less likely to suffer seriously, if at all, from the disease, and it seems that they are much less capable of spreading it.
