Ar 22 Chwefror, ysgrifennodd Andrew Goodall, y Cyfarwyddwr Cyffredinol Iechyd a Gwasanaethau Cymdeithasol a Phrif Weithredwr GIG Cymru at Brif Weithredwyr y Byrddau Iechyd, ynglŷn â Llwybr Cymunedol Cymru Gyfan ar gyfer COVID hir. Mae’r llwybr hwn yn ategu canllawiau clinigol NICE ar gyfer COVID hir, a gyhoeddwyd ym mis Rhagfyr 2020, ac mae’r Byrddau Iechyd yn defnyddio’r ddau hyn fel sail ar gyfer eu llwybrau lleol, gan sicrhau cysondeb o ran yr ymateb ar draws Cymru.
On 22 February, Andrew Goodall, Director General for Health and Social Services and the NHS Wales Chief Executive, wrote to Health Board Chief Executives with the All Wales Community Pathway for Long COVID. This Pathway complements the NICE clinical guideline for Long COVID, published in December 2020, both of which health boards are using to underpin their local pathways. This ensures a consistent response across Wales.
