Bydd llythyrau newydd oddi wrth Brif Swyddog Meddygol Cymru yn dechrau cael eu hanfon cyn hir at y rhai sy'n gwarchod eu hunain, gan gadarnhau'r newidiadau a gyhoeddwyd ddydd Sul 31 Mai a hefyd yn gofyn i'r rhai sy'n gwarchod eu hunain barhau i wneud hynny am gyfnod pellach. Nid oes dim newidiadau eraill yn cael eu gwneud i'r Cyngor i'r rhai sy'n gwarchod eu hunain ar hyn o bryd. Dylai pobl sy'n gwarchod barhau i ddilyn yr holl gyngor arall a roddwyd yn flaenorol. Ni ddylent fynd i siopa na mynd i'r gwaith y tu allan i'w cartref. Dylent barhau â’r drefn o gael bwyd a meddyginiaeth wedi’u cyflenwi ar eu cyfer.
New letters from the Chief Medical Officer for Wales will start to issue shortly to those who are shielding, confirming the changes that were announced on Sunday 31May and also asking those who are shielding to continue to do so for a further period of time. There are no other changes being made to the advice for those who are shielding at this stage. People who are shielding should continue to follow all the other advice previously given. They should not go shopping or attend work outside of home. They should continue to have food and medicine delivered to them.
