English: Thank you. What I will do, perhaps, is to first of all provide the context, so that you can understand where the idea emerged from, and why it came into existence. Then I will ask Barry to focus on the protocols followed. The drivers that led us to look at such a system was when we heard about the possible numbers of individuals who may be infected with this terrible virus, and what the forecast numbers of deaths within Ceredigion were. At the very outset, it was noted that if nothing at all happened, there was a possibility of 80 per cent of the population being infected and 1 per cent of those losing their lives. In terms of Ceredigion, that meant we were facing losing 600 residents by the end of June, and we decided that simply wasn't an option that could be considered. We moved very swiftly through a number of processes, very similar to other counties, in terms of lockdown, and having done that we reviewed the modelling. The forecasts even then were predicting some 200 deaths in the county, so we then asked the question, and I'm going back some nine or 10 weeks in the process, 'Well, what else can we do, because we have to get that number down? The loss of life is not an option within the county.' Barry recommended the development of our own track and trace system and that we should run with that. From that moment on, we decided to create a sub-committee within the council, and we drew in expertise from across the whole range of council staff. Barry chaired the panel, and we received excellent support from Hywel Dda health board; I do have to recognise the support we received from the health board. They were with us along the journey, then, in developing the model. So, if I can transfer to Barry, he can then explain to you how we developed the model.
Welsh: Diolch. Rwy'n credu beth wnaf i ydy rhoi'r cyd-destun yn gyntaf i chi gael deall o ble daeth y syniad, a pham daeth y syniad i fodolaeth. Wedyn gwnaf ofyn i Barry ymhelaethu ar y protocolau y gwnaethon ni eu dilyn. Yr ysgogyddion a wnaeth inni edrych ar system o'r math yma oedd pan glywon ni beth oedd y niferoedd posibl o unigolion a fyddai'n cael eu heintio â'r clefyd yma, a beth fyddai'r rhagamcaniadau ar gyfer nifer y marwolaethau o fewn Ceredigion. Reit ar y cychwyn, fe nodwyd, os na fyddai unrhyw beth yn digwydd o gwbl, y byddai posibilrwydd o 80 y cant o'r boblogaeth yn cael eu heintio ac 1 y cant o'r rheini o bosibl yn colli eu bywydau. Wel, i drosi hwnna i mewn i ffigurau Ceredigion, roedd hwnna yn golygu ein bod ni'n wynebu colli 600 o drigolion y sir erbyn diwedd Mehefin. Penderfynon ni nad oedd hwnna'n opsiwn i ni ei ystyried o gwbl. Fe symudon ni'n gyflym iawn trwy nifer o brosesau, yn debyg iawn i bob sir arall, a hynny yw, cloi'r sir lawr, ac ar ôl gwneud hynny i gyd, ailadolygu'r modelu, a hyd yn oed wedyn byddai'r rhagamcaniadau dal yn darogan tua 200 o achosion o farwolaethau o hyd yn y sir. Felly, mi ofynnon ni'r cwestiwn, wedyn - a dwi'n mynd nôl nawr obeutu naw, 10 wythnos yn y broses - fe ofynnon ni'r cwestiwn wedyn, 'Wel, beth arall fedrwn ni ei wneud, achos mae'n rhaid cael y rhif yna lawr? Dyw colli bywydau ddim yn opsiwn gyda ni yn y sir.' Ar yr adeg honno, fe wnaeth Barry argymell, 'Beth obeutu datblygu system olrhain ein hunain a rhedeg ag e?' O'r eiliad yna ymlaen, fe benderfynon ni greu is-bwyllgor o fewn y cyngor, ac fe dynnon ni arbenigeddau reit ar draws rhychwant eang o staff cyngor. Barry oedd yn cadeirio'r panel, ac fe gawson ni gefnogaeth ardderchog gan fwrdd iechyd Hywel Dda; mae'n rhaid cydnabod y gefnogaeth gawson ni gan y bwrdd iechyd. Buon nhw gyda ni ar hyd y daith, wedyn, yn datblygu'r model. Felly, os gwnaf i drosglwyddo i Barry, fe gaiff e esbonio ichi, wedyn, sut wnaethon ni greu'r model.
