Mae’r Rheoliadau Teithio Rhyngwladol yn cael eu hadolygu’n gyson, ac ar 18 Ionawr cafodd y coridorau teithio eu hatal. Nid yw’r trefniadau presennol ar gyfer teithio o fewn yr Ardal Deithio Gyffredin (y Deyrnas Unedig, Iwerddon, Ynys Manaw ac Ynysoedd y Sianel) wedi newid felly caniateir teithio o fewn yr ardal hon heb orfod ynysu.
The International Travel Regulations are kept under review, and on 18 January the travel corridors were suspended. The current arrangements for travel within the Common Travel Area (CTA) (UK, Ireland, Isle of Man and the Channel Islands) are unchanged so travel without isolation is still permitted.
