English: Thank you. On your final question, I have to say I'll happily take that and have a further discussion with the chief medical officer's department about shielding and families and advice that we should give to people about how to best protect themselves and their loved ones. I recognise there are genuine concerns that people have. On the move to level 4 before Christmas, I do believe that we've been vindicated in the move that we took. I think it was absolutely the right thing to do. I've yet to see the measures that are being taken in England, and I completely expect that there will be more communities moving into higher levels of restriction because of the reality of the spread of the virus, and the reality that, without additional action being taken, parts of our healthcare system could otherwise face being overwhelmed. We can't expect our staff to run through brick walls on our behalf for another three months. We all need to be part of doing the right thing. That includes the Government, but it includes the public as well. On the new variant and the school return, I have commissioned some further work from the technical advice group to understand not just the impact on transmission and children, but to understand what it means for how safe the school environment is, because whilst teenagers in particular are able to not just get the virus but pass it on to others, actually, they themselves are very unlikely to suffer harm. Conversely, though, I know that there are concerns for people who work in schools, but, actually, we don't have any real evidence of there being any kind of significant level of pupil-to-staff-member transmission, and that, I think, does show how successful our schools have been, and it's a real positive for them, about having a COVID-secure learning environment. What we do see, though, is some staff-to-staff transmission, and that's about people following the requirements in their own workplace to keep themselves and colleagues safe, and it's also about making sure that the mixing outside school doesn't take place as well, and that's why the stay-at-home period is so important for us as well. What's different about the last week before Christmas, where we moved all high schools to distanced learning, is that non-essential retail was open for a period of time in that week. It's also the case that we didn't have a stay-at-home requirement, for people to only leave home for essential purposes. So, we're operating in a very different context moving into the new year, with the phased return that's been agreed, compared to that last week in December. But I do think that the research that I've commissioned from TAG, which I'd like to publish as soon as possible, will help to give more confidence not just to staff, because I am concerned that staff have confidence to return to school, but confidence to parents and learners as well that they will be able to receive some face-to-face teaching and learning, because we know that's vitally important not just for a general sense of well-being and mental health, but actually to get good qualifications at the end of this year as well, and I would not want to see that compromised, if at all possible. As ever, if the evidence changes, we'll need to consider what they means for us and the decisions we make. I want to assure the Member that I do have regular conversations not just with our chief medical officer and scientific advisers, but also regular conversations with the education Minister as well, to make sure that we understand how our plans are moving, including of course the plans for serial testing for secondary school aged children going back to school from January next year.
Welsh: Diolch. Ar eich cwestiwn olaf, mae'n rhaid i mi ddweud y byddaf yn hapus i wneud hynny a chael trafodaeth bellach gydag adran y prif swyddog meddygol ynghylch gwarchod a theuluoedd a chyngor y dylem ei roi i bobl ynglŷn â'r ffordd orau o ddiogelu eu hunain a'u hanwyliaid. Rwy'n cydnabod bod pryderon gwirioneddol gan bobl. Wrth symud i lefel 4 cyn y Nadolig, rwy'n credu bod y newid a wnaethom wedi'i gyfiawnhau. Rwy'n credu'n bendant mai dyna'r peth iawn i'w wneud. Nid wyf eto wedi gweld y mesurau sy'n cael eu rhoi ar waith yn Lloegr, ac rwy'n llwyr ddisgwyl y bydd mwy o gymunedau'n symud i gyfyngiadau ar lefelau uwch oherwydd realiti lledaeniad y feirws, a'r realiti y gallai rhannau o'n system gofal iechyd gael eu gorlethu oni bai ein bod yn rhoi camau ychwanegol ar waith. Ni allwn ddisgwyl i'n staff redeg drwy waliau brics ar ein rhan am dri mis arall. Mae angen i bob un ohonom fod yn rhan o wneud y peth iawn. Mae hynny'n cynnwys y Llywodraeth, ond mae'n cynnwys y cyhoedd hefyd. Ar yr amrywiolyn newydd a dychwelyd i'r ysgol, rwyf wedi comisiynu gwaith pellach gan y grŵp cyngor technegol i ddeall nid yn unig yr effaith ar drosglwyddiad a phlant, ond i ddeall beth y mae'n ei olygu o ran pa mor ddiogel yw amgylchedd yr ysgol, oherwydd er bod pobl ifanc yn eu harddegau yn enwedig yn gallu dal y feirws a'i drosglwyddo i eraill, maent hwy eu hunain yn annhebygol iawn o ddioddef niwed mewn gwirionedd. Fodd bynnag, gwn fod pryderon i bobl sy'n gweithio mewn ysgolion, ond nid oes gennym unrhyw dystiolaeth wirioneddol fod unrhyw fath o lefel sylweddol o drosglwyddo gan ddisgyblion i staff, ac rwy'n credu bod hynny'n dangos pa mor llwyddiannus y bu ein hysgolion, ac mae'n gadarnhaol iawn iddynt hwy, o ran cael amgylchedd dysgu sy'n ddiogel rhag COVID. Yr hyn a welwn, serch hynny, yw rhywfaint o drosglwyddo rhwng aelodau staff a'i gilydd, ac mae hynny'n ymwneud â phobl yn dilyn y gofynion yn eu gweithle eu hunain i gadw eu hunain a chydweithwyr yn ddiogel, ac mae hefyd yn ymwneud â sicrhau nad oes cymysgu y tu allan i'r ysgol yn digwydd hefyd, a dyna pam y mae'r cyfnod aros gartref mor bwysig i ni. Yr hyn sy'n wahanol am yr wythnos olaf cyn y Nadolig, pan wnaethom symud pob ysgol uwchradd i ddysgu o bell, yw bod manwerthu nad yw'n hanfodol ar agor am gyfnod o amser yn yr wythnos honno. Mae'n wir hefyd nad oedd gennym ofyniad i aros gartref, i bobl adael eu cartrefi at ddibenion hanfodol yn unig. Felly, rydym yn gweithredu mewn cyd-destun gwahanol iawn wrth symud i mewn i'r flwyddyn newydd, gyda'r dychweliad graddol y cytunwyd arno, o'i gymharu â'r wythnos olaf ym mis Rhagfyr. Ond rwy'n credu y bydd yr ymchwil rwyf wedi'i chomisiynu gan y grŵp cyngor technegol, yr hoffwn ei chyhoeddi cyn gynted â phosibl, yn helpu i roi mwy o hyder nid yn unig i staff, oherwydd rwy'n awyddus i staff gael hyder i ddychwelyd i'r ysgol, ond hyder i rieni a dysgwyr hefyd y byddant yn gallu cael addysg a dysgu wyneb yn wyneb, oherwydd gwyddom fod hynny'n hanfodol bwysig nid yn unig er mwyn cael ymdeimlad cyffredinol o les ac iechyd meddwl, ond i gael cymwysterau da ar ddiwedd y flwyddyn hon hefyd, ac ni fyddwn am weld hynny'n cael ei beryglu, os yw'n bosibl o gwbl. Fel erioed, os bydd y dystiolaeth yn newid, bydd angen inni ystyried beth y mae hynny'n ei olygu i ni a'r penderfyniadau a wnawn. Rwyf eisiau sicrhau'r Aelod fy mod yn cael sgyrsiau rheolaidd nid yn unig gyda'n prif swyddog meddygol a'n cynghorwyr gwyddonol, ond sgyrsiau rheolaidd hefyd gyda'r Gweinidog addysg, i sicrhau ein bod yn deall sut y mae ein cynlluniau'n symud, gan gynnwys y cynlluniau ar gyfer cynnal profion cyfresol ar blant oedran ysgol uwchradd sy'n mynd yn ôl i'r ysgol o fis Ionawr y flwyddyn nesaf.
