Mae hefyd yn bwysig iawn lleihau cyswllt cymdeithasol ar ôl gweld eich swigen Nadolig, er mwyn lleihau'r risg o gadwyni trosglwyddo. Mae hyn yn cynnwys peidio â chwrdd â ffrindiau neu deulu y tu allan i'ch cartref ar gyfer Nos Galan. Bydd y rheolau haen neu lefel ar waith ar Nos Galan / Hogmanay ac mae'n hanfodol, fel isafswm, bod pawb yn cadw at y rhain.
It is also really important to cut down on social contact after seeing your Christmas bubble, to reduce the risk of chains of transmission. This includes not meeting up with friends or family outside your household for New Year’s Eve. The tier or level rules will be in place on New Year’s Eve / Hogmanay and it is essential, as the minimum, that these are followed by everyone.
