Wrth inni gasglu rhagor o ddata am COVID-19 a dod i’w ddeall yn well, mae’n briodol y dylem ailystyried ein dulliau gweithredu mewn perthynas â’r cwestiynau allweddol hyn. Rydym wedi cael cyngor gan y Grŵp Cyngor Technegol ynglŷn â’r ddau bwnc hyn, ac rwy’n cyhoeddi’r cyngor hwnnw heddiw. Dyma sail y safbwyntiau a gyhoeddir heddiw ar brofion wrth ryddhau cleifion a hyd brigiadau o achosion.
As we gather more data on Covid and our understanding develops, it is right that we should revise our approaches to these key questions. We have advice from the Technical Advisory Group, which I am publishing today, around these two topics, and this underpins the positions on discharge testing and on duration of outbreaks which I am announcing today.
