As anticipated, this affected the testing data flows from the WLIMS, therefore there was no update of the Public Health Wales (PHW) dashboard figures on Sunday 13 December 2020.
Fel y disgwyliwyd, mae hyn wedi effeithio ar lif data profion o’r WLIMS, felly ni chafodd ffigurau dangosfwrdd Iechyd Cyhoeddus Cymru eu diweddaru ddydd Sul 13 Rhagfyr 2020.
