Mae'r canllawiau ynghylch hunanynysu yn newid. Bydd gofyn i oedolion sydd wedi'u brechu'n llawn a phlant a phobl ifanc rhwng 5 a 17 oed hunanynysu nes eu bod wedi cael prawf PCR negatif os bydd rhywun ar eu haelwyd yn arddangos symptomau neu’n cael prawf positif ar gyfer Covid-19.
The guidance around self-isolation is changing. Adults who are fully vaccinated and children and young people aged five to 17 will be asked to self-isolate until they have received a negative PCR test if someone in their household has symptoms or tests positive for Covid-19.
