Ddoe, derbyniais lythyr gan Grant Schapps, Ysgrifennydd Gwladol dros Drafnidiaeth Llywodraeth y DU, yn rhoi gwybod i mi am adroddiadau gan awdurdodau iechyd Denmarc ynghylch achosion eang o SARS-CoV-2 ar ffermydd minc, a bod amrywiolyn minc o’r feirws wedi lledaenu i'r gymuned leol. Nodwyd o leiaf saith mwtaniad unigryw i’r feirws mewn minc. Mae un o'r amrywiolion firysau hyn, gyda phedwar newid yn y protein sbigyn, wedi'i ganfod ar bum fferm minc ac mewn 12 o bobl yn y gymuned gyfagos.
Yesterday I received a letter from Grant Schapps Secretary of State for Transport informing me that Health authorities in Denmark had reported widespread outbreaks of SARS-CoV-2 in mink farms, with subsequent spread of a mink-variant virus to the local community. At least seven unique mutations have been identified in the virus in mink. One of these virus variants, with four changes in the spike protein, has been found on five mink farms and in 12 people in the surrounding community.
