Rydym yn parhau i argymell bod pawb sy’n cael ei nodi fel cyswllt agos, boed wedi eu brechu neu beidio, yn cymryd prawf PCR ar yr ail ddiwrnod a’r wythfed diwrnod ar ôl iddynt ddod i gysylltiad ag achos positif.
We continue to recommend everyone identified as a close contact, whether they have been vaccinated or not, undertakes a PCR test on day two and day eight following their exposure to a positive case.
