Yn anffodus, o ganlyniad i benderfyniadau a wnaed gan Lywodraeth y DU, bydd casglu data o dan gam presennol yr Arolwg Heintiadau Covid-19 nawr yn cael ei atal tra bydd penderfyniadau’n cael eu gwneud am fodelau gwyliadwriaeth yn y dyfodol. Rwyf wedi ysgrifennu at yr Ysgrifennydd Gwladol dros Iechyd i fynegi fy siom dwys a’m pryder ynghylch colli’r darn pwysig hwn o wyliadwriaeth.
Unfortunately, as a result of decisions made by the UK Government, data collection under the current phase of the Covid-19 Infection Survey will now be paused while decisions are made about future surveillance models. I have written to the Secretary of State for Health to express my deep disappointment and concern about the loss of this important piece of surveillance.
