Mae hyn yn golygu bod yn rhaid i bobl sydd wedi profi'n bositif am COVID-19 hunanynysu am saith diwrnod. Ar ddiwrnodau chwech a saith o'u cyfnod hunanynysu dylent gymryd profion llif unffordd ac os yw'r profion hyn – i’w cymryd 24 awr ar wahân – yn bositif dylent barhau i hunanynysu.
This means people who have tested positive for COVID-19 must self-isolate for seven days. On days six and seven of their self-isolation period they should take lateral flow tests and if these tests – taken 24 hours apart – are positive, they should continue to self-isolate.
