Could I make it absolutely clear that the information that I have to date regarding COVID-positive cases in school at this stage relates to the infection being acquired outside of the school premises? I think that's really important to state. Where we've had children testing positive for COVID, that is usually part of a family grouping and, where we have had adults testing positive for COVID at this stage, the data I have would suggest that, again, the virus has been acquired outside of school. And that's why it is really, really important—if we are to do what we all want to do in this Chamber, to keep our schools open, then all of us have a responsibility to do what we can to keep community transmission rates of the virus really low. Where we're seeing the biggest disruption to education at the moment, it mirrors where we're seeing the virus in the community, in Caerphilly, in Rhondda Cynon Taf, in Newport—not exclusively, of course, because there are schools in other parts of Wales that are affected, but we have to keep transmission rates down and it's really important.
