Cyngor Grŵp Cynghori Gwyddonol y DU ar Argyfyngau (SAGE) a'n Cell Cyngor Technegol (TAC) yw mai rhoi ymyriadau ar waith yn gynharach a chyn i’r cyfraddau dyfu fwyfwy yw'r ffordd fwyaf effeithiol o reoli'r pandemig. Mae'n ymddangos bod system lefel 3 yr Alban a chyfyngiadau haen 3 Lloegr yn cael effaith gadarnhaol ar leihau lledaeniad y coronafeirws. Rwyf felly'n cefnogi'r diwygiadau arfaethedig i reoliadau Cymru er mwyn gwahardd gwerthu alcohol a lleihau’r oriau agor mewn tafarndai, bariau, bwytai a chaffis, ac er mwyn cau lleoliadau ac atyniadau adloniant o dan do.
Advice from UK Scientific Advisory Group on Emergencies (SAGE) and our Technical Advisory Cell (TAC) is that implementing interventions earlier and before exponential growth is the most effective way of  controlling the pandemic. The Scottish level three system and the English tier three restrictions appear to be having a positive impact on reducing the spread of the Coronavirus. I therefore support the proposed amendments to the Welsh regulations to prohibit the sale of alcohol in and reduce the opening hours for pubs, bars, restaurants and cafes, and to close indoor entertainment venues and attractions.
